Oh no, I wasn't gonna crack the crank case! I can tell that's fine. I'm talking about rebuilding the carb, rewind, magneto, cutout switch,lower unit & gearcase. Right now I can't seem to figure out how to get the magneto open! Been at it for an hour!!!

Are you trying to pull the flywheel off so you can get to the points and coils?
To get it off you need a flywheel puller (harmonic balancer puller OK) with 1/4-20 grade 8 bolts.

PULLING FLYWHEEL

you need a harmonic balancer puller, you need 3 - #8 harden bolts, that fit the 3 holes in your flywheel. standard hardware store bolts will strip out, causing more problems. loosen the flywheel nut, leaving it on so it protects the thread. thread the bolts in 7/16 of an inch. then tighten the puller, adjust so it has a straight pull. now tighten the puller, rap the center bolt with a hammer, then tighten some more. you may have to let it sit over nite, and repeat in the morning. this is a compression fitting, it will eventually POP!!. do not loose the woodruff key that goes in the groove of the flywheel and the crank shaft. then installing the flywheel, it has to be totally clean, no oil, woodruff key in place. then torque the nut to the specifications for your particular motor. if you do not do this, the woodruff key with shear, and you will be repeating these steps.

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

about everything make sur eu change the water pump too. u have the right idea of over haulign everything. but u ahve to check compressio first please. if ur coimpression aint good then all the other stuff will be worthless.

little tip on the water impeller u have to taske the back cover off to see the hidden bolt. make sure u diengage the shift rod before u dorp the lowerunit. and when it does come off it will come off pretty hard to be careful.

for the carb u need to take the electric start off first ok. and if u cant pull the fuel line off just snip it off and replace all the fuel and air lines with 1/4" acholhol restitant line

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

Yeah, I started taking off the carb & figured out quick that it wasnt going anywhere till the starter was off, which required the rewind to come off ... HA!! I got it all off though, just got stuck on the magneto ... shoulda known I'd need some fancy gizmo to get it off! UUGGHH!!! I'll track one down asap I guess. On hold for now. Was trying to do the stuff that didn't cost $ right now! Never fails! Takes $ to breathe it seems sometimes!LOL! Since the carbs off, can I still check the compression or is that hole gonna have to be plugged? Oh, and is there a fitting that I can just hook up to my air pump that has a pressure gauge?

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

To check the compression, you screw a compression gauge into the spark plug holes and crank the engine over to see what pressure the pistons produce.

An auto parts store may lend you the compression gauge and harmonic balancer puller for free.

You need to get some sort of repair manual for this motor; the main library branch may have one. This isn't hard, but the first time through takes a bit of patience. Don't try to do everything at once.

It's best to go about getting the motor running systematically. Here's the order I do things:
Check the compression. The readings should be within 10 percent of one another.
Check the spark. If it's not good on one or both cylinders, then I put in new coils, points and condensers.
Change the water pump impeller if I don't know how old it is.
Change out the lower unit gear lube and make sure it shifts in and out of gear.
THEN, I try to start it in a barrel of water. If it doesn't run, then I know I have good compression, good spark, and all that's left is the fuel system.
If there is a problem with the fuel system, then I get a carb kit, disassemble and thoroughly clean the carb, and re-assemble with the new parts from the carb kit.

I can usually do all of this easily in a weekend, probably a grand total of 6 hours of leisurely paced work if I have to change the ignition parts, replace the impeller, and rebuild the carb. Broken bolts, now that's another story.....

Check with Autozone. They have stores in the Memphis and Little Rock area. I know they will loan you a compression tester for free. Keep it as long as you want. They will refund your deposit when you return it.

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

OK folks, good news & bad news .... compression's good at 120 both cylinders ..... top cylinder plug has a great spark ... bottom plug, nada BUT it may just be the plug wire, cause it has a bad crack in the wire just behind the terminal cover. Any way to see without pulling the magneto?

 

[lonewolf8814]

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

oh yeah, and now I know the starter works good too!

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

Great compression. Now you know you have a good motor.

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

OK guys, I got my magneto cap off & checked my coils with a multimeter. They seem to be fine! Moreover, all the parts inside look brand new!! Thing is, the point to the coil that wasn't firing was quite a bit further away from the so I just turned the eccentric screw & moved the point in closer. Plus, the points were also a bit gunked up, so I hit them up with some pipe flux & a toothbrush. Gonna see in a sec if it works or not. Question= is a square with an "M" inside mean it's a mallory part? If so, this motor is loaded with new mallory parts!!!!

 

[lonewolf8814]

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

MORE GREAT NEWS!!! Got some new spark plugs & set the points at 020 like the flywheel said ... PRESTO! She's firing like a champ on both lines now!!

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

Great job!
Now you got compression and spark.
Only thing left is fuel.
Make sure to torque the flywheel down properly.
I don't know the correct value for your engine, but it's important.

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

GREAT NEWS!! I got my carb & fuel pump rebuild kits!! And my new impeller too! http://s101.photobucket.com/albums/m76/lonewolf8814/lonestar/
Found out why my high speed needle valve was froze up ... There's a TON of old hardened fuel in the bottom of the float chamber!!! Has the valve glued solid! I'm soaking it in paint thinner right now, trying to break down the gunk.

 

[tashasdaddy]

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

this is what you are dealing with. build up on the exposed part of the needle. could be a few threads also. if the paint thinner does not cut it. put some carb cleaner in there. if that does not do it try boiling it in a pot of water.

 

[lonewolf8814]

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

Well, the paint thinner didn't do jack, so I tried some acetone! Voila, that gunk's melting away faster than a corner girls makeup in the rain!!LOL!

 

[coolguy147]

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

make sure u only ur fingers to pry to needle out and by the way take out the nut that holds ain the packing and get a smalle item to try to pry the old oens out. get some carb cleaner and spray it everywhere and keep working it back and forth

 

[lonewolf8814]

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

OK guys, for future reference, when it comes to cleaning a fouled up carb, tell everyone to put the carb in a coffee can (one of the plastic ones with the built in handle is great!) & bathe it with acetone. It's got my carb looking like it's brand new!! Forget the carb cleaner spraying & all that! LOL! All that gunk came off like magick!!

 

[tx1961whaler]

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

Make sure to blow out all of the passages in the carb with compressed air, if you can.

Re: HELP!!!! 1966 johnson super sea-horse 33 electric

Hey I just came into a 1966 40 HP Super Sea Horse, where do I get some exploded views? All the boat part websites stop at 1968? I have a book on hold for me at the pubic library that may help, but not much else to go on. Please point me in the right direction.
