gamefisher throttle and other questions

[callmecrazy]

Hi,

Just acquired an 80's gamefisher 1.2 (tanaka TOB-120) and I have a few questions.

The motor runs with the throttle lever in the 'start' position with the prop spinning. But when i push it to 'stop' the motor shuts down. So there's no way to run it at idle without the prop spinning. So, is this normal? is it an idle adjustment, throttle adjustment, etc..?

Second, The carb float keeps getting stuck. It happens usually within a minute or two after starting the motor. I've taken the carb apart and cleaned it well several times now. There is a little spring thingy shaped like a C that pushes a needle valve. the needle is apparently not seated on the C-spring thingy (whats it called?) correctly. I've messed with it a bit, and every time I think its working, it happens again.

Third, I want to get a spare prop and shear pin, just wondering if it would make any difference to put a 3.0hp prop on the 1.2?

Thanks

Re: gamefisher throttle and other questions

That little screw on the side of the carb is the idle control screw, and all it does is hold the carb slide up enough for the motor to idle without the centrifugal clutches engaging and turning the prop. You may not even need a spare prop, since the motor hardly has enough power to damage the prop that's on the motor. About a 1/8" or 3/16" diameter piece of brass rod or screw can make you a great shear pin. The float needle valve may have some gunk of varnish in it and need cleaning. Good Luck!

That little screw on the side of the carb is the idle control screw, ] Lol,I was about to post about throttle control too,"just to add",on my 1.75 ,.I found you can adjust the iddle on the throttle cable, unscrewing makes the iddle go up,and viseversa its like the brakes on the handle bars of a bike.I used to use the screw adjustment on the carb,but after I added an air filter to the intake it was very difficult to get in there ,.I was forced to find another way,since I was so proud of my latest mod,so I did it,Paul pro prevailed, its even easier than adjusting it at the carb,take it from me,Paulpro knows boating like Bo knows baseball..:facepalm:O, about the prop,just get a spare,I would try one from my motor 1.75.I would only go bigger if you decide to run dual motors,or twinns which is what I,m about to do each motor has "same model#",Also first check if it would even fit,you may have to grind,the 3.0 prop will be a close fit even for my moto,.only difference is the length of each blade,same width thoughhere is my motor and the one I just won,delivered Dec 1st.,Lets hope she runs as good as she looks.P.S I lost bidding wars on this prop,did anyone here get it,damn,I fell asleep[video]twin outboards[/video],copy this link for youtube,check under boater 305,scroll down a bit,new vid youtube MrHukaspukas under that channel you can find the twin motors running

hmm,I believe the prop on the 3 is "opposite pitch" so no,,but I'm not sure its the same on all 3's,just make sure of this. The powerhead on the 3hp is reversed with the piston and cylider facing the front of the motor,and they didn't use a reverse set up in the lower unit to compensate lolI also need to find bigger props so I can run duals and keep the rpm 's down on my solo trips,pleas help,I'm gonna check with my buddies prop to see if their the same set up ,my blade pushes counter clockwise I hope Noel's 3 is the same,check ebay,I just got a spare prop,the bidder canceled his bid so I was able to buy it after all,33.00 plus $6 shipping ,search under Tanaka,my prop comes with a shear pin.

Re: gamefisher throttle and other questions

thanks for the info.

about the throttle/idle, am I correct the 'stop' position should stop the prop from spinning and the motor continues idling? or is it 'stop' as in turn off the motor?

thanks

WEll after meditating on it,I finally searched the archives.YEs you shut it off from the throttle on the handle,lol you can get it to iddle down way low ,if you continue to throttle down it will shut off,have fun but steer clear from rough seas

Re: gamefisher throttle and other questions

Thanks again.

I did search the archive a few times, but didn't come up with anything. Appreciate the help.

Remember,you have to meditate on it first before searching the archives,,,Also remember "Paulpro knows boating like Bo knows baseball"I have two none working 1.75's at the present time I need carb cleaning help lol.Though,I did get to run them both on my 10' jonboat,also made by sears,any tips for carb cleaning,I've never felt so helpless in my life,its a feeling of despair,on the positive side I am loosing weight over the matter,and not to mention sleep,but who needs sleep these days

Re: gamefisher throttle and other questions

Did you get all the kinks out of your 1.2?I got both my motors running, it where the plugs fouled up.One day I did a trip with both motors ,one would'nt start back ,and the other shut off while running,and would'nt start back either,I got a couple of ngk plugs, the original plugs.Botjh motors are running strong,I'm using echo,oil mix and reg gas,and am running sea foam 2 ounce per gal,in one and 1 ounce for the newer motor,motors scream and plane my boat ok,seems like I'm going more than twice as fast as one,I just dowloaded a new vid 3 hours ago of my twinn 1.75's,no direct link yet.Youtube boater 305,from there click boater 305 underneath any of his videoes,in his channel will pop up the vid with twin motors starting from a cold start,enjoy and thanks,more vids soon,but on payper view,I'm close to living my dream and running tripples,I may have to have costum props made if I can't find bigger props,motors rev higher running together ,but its good for them,these motors are recommended to mostly be ran at full throttle,just don't exceeed those max 8000 rpm's,I later mounted them higher with each on a block of wood I mounted for running my one in shallow water.

Re: gamefisher throttle and other questions

I was able to get it running. The carb float still sticks occasionally, and I stripped the tiny little flathead screw that holds the float spring-thing in place. So I'll never be able to fix it agan But its working fine right now.

I'll eventually get a new carb for it... I'm using sta-bil and regular gas. It pushes my little 8'8" Achilles pretty well. Much better than rowing

I'm still a little surprised I can't get it to idle low enough to stop the prop. So I have to cut the motor off as I come up to the dock or boat. But it's ok, I can always row a few feet if I need to.

Re: gamefisher throttle and other questions

did you ever mess with the idle adjuster thingamajigger on the side of carb,,or do you have an idle adjuster on the handle ,anything on the throttle cable where you can adjust?,as long as your happy

 

[callmecrazy]

Re: gamefisher throttle and other questions

The screw on the inside of the carb seems to be in a fixed position. It doesn't tighten down much more than it already is, and when I try to loosen it (even just a tiny, tiny, bit) it becomes much too loose. As if it would fall out... I haven't completely disassembled it yet though, but since I'm planning on buying a new carb anyway, i'm not too worried about it.

I looked at the throttle cable at the handle and couldn't see where it could be tightened. But I only looked for a minute... I'll try again in the spring

Re: gamefisher throttle and other questions

buying a new carb

what wrong with the old carb besides needing a rebuild?Oh and P>P if you do a litle more searching you would find that used prop you payed $33 for is like $24 from hitatchi main office is in Atlanta....I have seen those little buggers sell for $50 on ebay while the new set there all ready to go cheap....I guess those 1.75 are hard to tear up a prop unless you drop the engine...and by the way don't put a 3hp prop on you 1.75, the pitch change will eat that engine and you will learn fast what wasted money is....mrcrabs knows wasted money like PP knows???

best regards,

[up a QUOTE=mrcrabs;3572801] the pitch change will eat that engine and you will learn fast what wasted money is..The powerhead on the 3hp is reversed with the piston and cylider facing the front of the motor..with a 3 prop you will go backwards on a 1.75 ,so far there is no prop that I know of to go bigger,Paulpro knows just like Bo knows,to see my motors running check youtube for [video]identical outboard twins[/video],also see[video]twin outboards[/video],also [video]boating in bay [/video],enjoy,here are my identical twins I've been wanting to share,its my first time ever running duals ,we do what we must to be happy,just wait till I make a solo run vid,the two motors plane my boat ok,I'm using the # 4 whole on the tilt,I'm gonna try the 5th to see if it pushes the bow down,no gps reading yet but soon.Whack my vids, it'll be fun,you'll feel just as if your ridding alongOne mans boat is another mans dream,Sincerely,PP,P.S,I only wanted bigger props since I run duals now,the rpm's are up there,I've been messing with different hights for the motors,I had raised them for going extra shallow,but I just lowered them a bit to avoid cavitation ,motors scream with me alone

I can't ,my solo run is on payper view only,but if you copy boating in bay then paste to youtube it should pop up,scroll down a bit,you'll see the screen shot. identical twin outboards should pop up as the first vid up topalso twin ouboards should pop up at top,"running together out of water",they sound great,thanks.I hope you enjoy watching,and I new you'd love the screen shot from the actual vidP.S. One motor shuts off sooner after closing pepcock valve,also it revs up as it runs out of gas,although they are twins ,they sure act diff,even sound diff too? but together,they sure run fast

Re: gamefisher throttle and other questions

I like to cut them off early so they can cool down,I got my motors running like a top,have a good year,and enjoy my vid,I want to share my joy

Re: gamefisher throttle and other questions

The 1.2 hp gamefisher / tanaka carb is not adjustable. It is factory set. Also the motor is direct drive no clutch, so when the motor is running, even at low speed, the prop will be turning.

Dont worry about the screw that holds the float arm in, unless it is dirty or stuck in the float arm and restricts the arms movement. Be sure to seal the outside of hole where the screw is.

 

[callmecrazy]

Re: gamefisher throttle and other questions

Thanks for the clarification. You are correct, the carb wasn't adjustable and the prop keeps spinning no matter what

The screw that holds the float arm is the only problem left. It is definitely restricting the arms movement. I can't unscrew it because it's completely stripped.
cleaning it helped and got it loose enough to work for now. but it still sticks occasinoally, and I'm betting it will get stuck at the worst possible moment. So, I'll probably just spend the $80 on a new carb... But then again, a gamefisher 3.0 just showed up on CL today for $130, and a really nice nissan 3.5 for $200... anyone want to buy a 1.2?
