Re: 120 evinrude still acting up

I think your okay, but I'd check #3 again to make sure it flows to the cylinder. Pul a suction on the hose with your syringe.

Re: 120 evinrude still acting up

OK I just went out and tried the syringe and I found a hose that was cracked. it was where the line that comes from #3 to a tee from the tee to the crankcase a piece about 1 inch long was busted. Could this be a potintial culprit of my problem?

Re: 120 evinrude still acting up

I got the tubing fixed this morning and pulled all four recirculation fittings. The screen was a little black so I cleaned and blew air through them and everything is clear. I ran it and #1 is spitting a little bit of fuel and #3 isnt. It is pulsing a little bit of air though. This is the one that ties into the larger tube that goes from top to bottom so it may be going that way. I dont know. I couldnt get to the # 2 & 4 while running. I ran it for about five minutes and pulled the plugs out and it was very wet. Just looks like excess fuel. ones these plugs are saturated like that could that cause weak fire when under compression?

Re: 120 evinrude still acting up

I was reading the FAQ on decarb does it sound like I might need to do that? I noticed when I pulled the plugs out, the top of the piston is very black.

Re: 120 evinrude still acting up

Sorry again it is a check valve. Im doing a decarb per the post in the FAQ and sure is a lot of black oil dripping out of the exaust .
Thanks

Re: 120 evinrude still acting up

Nothing is working . Even though I did find a hose problem it still want run right . Heres the latest.
I ran it today after decarb and new plugs.
Take off it gets to about 2700 RPM and want break over. No missing or spudering if I lean foward It gets to about 2900 RPM and gets on top of it. Then top end gets to 5200 and nothing more. Motor sounds good but no ump. I come back to idle and does OK until Im tring to load and putting in gear at Idle and I get a puff here and there and it dies on and off while trying to load up.
Makes you want to chew nails@#%@#&*
What realy messes with me is after I had the new pack and timmerbase put on it ran great for 6 or 7 runs got out of the hole great and on top 5800 RPM or more. And then Bam its Back. I Just dont understand
what should I do next?

Re: 120 evinrude still acting up

After just slowing down a minute Im starting to see the engine be the engine. I rember when I had her apart and rebuilding the carbs I didnt soak the throttle body. Or remove the core plugs. My kit didnt have those plugs. Im relooking at the manual and I see where they are removing the core plugs Is this possibly where I missed the mark. The carbs are plastic so I didnt soak those just disasembled the parts cleand with carb cleaner and put new parts back in. Could I have made a rookie mistake here ?
Thanks
Im so low a snake could poot and it would blow sand in my eyes

Re: 120 evinrude still acting up

I soak those plastic carbs in Berryman Chemtool all the time and have never damaged a carb body with the stuff.
Your carbs don't have core plugs.

Your carbs don't have core plugs.
I soak those plastice carbs in Berryman Chemtool all the time and have never damaged a carb with the stuff.
Don't get Chemtool or any other carb cleaner near the oring gaskets though. They will grow like Stretch Armstrong.

 

[hookedonjc]

Re: 120 evinrude still acting up

The core plugs are on the throttle body. I just got done pulling them out. I dont see any pluggage but Im going to soak them and the carb body like you said. On the carb floats the manual calls for floats to be level with gasket surface when chamber is inverted. how critical is this could this give the symptoms im having if its out of calibration ?

Re: 120 evinrude still acting up

Test the spark with the spark plugs removed. The spark should jump that 7/16" gap with a strong blue lightning like flame... a real SNAP! Does it?

Recheck the compression which should be approximately 100 psi and even on all cylinders. Is It?

Spark plugs should be Champion QL77JC4 plugs, and gapped at .040 (I know the book says .030). Are they?

If the area above are as they should be, and assuming that you haven't retarded the timing, and taking into consideration the fact that according to you, after having the timer base and powerpack replaced the engine ran fine for three (3) trips before reverting back to the same problem...... I would suspect a possibly intermitent short at ther ignition switch which would cause a slight amount of voltage to be applied to the black/yellow wire (kill circuit) of the powerpack.

Check that possibility by removing the black/yellow wire from the back of the powerpack. If the problem ceases to exist, replace the ignition switch. Note that it will be impossible to kill the engine via the ignition switch with that wire removed.

Note.... If the carburetors were at fault, replacing the timer base and powerpack previously would have had no effect on the problem.

Re: 120 evinrude still acting up

Thanks Joe
I have checked spark and it a good 7/16 on all four. The compression is
#1 - 130 psi #2- 115 psi #3- 125 psi #4-120 psi
I do have the QL77JC4 plugs but they are gapped at .030 I will change that to .040
I will try pulling the Black/Yellow off the pack that I havent tried yet.
I Had aready pulled the carbs back off so Im going to clean every thing again, like you stated I dont see any plugage in the carbs or the throttle base.
While I got them apart is there any thing I should look for that is critical?
Thanks for helping

Re: 120 evinrude still acting up

Make sure none of the emullsion tubes are cranked and make sure the little clips that hold the float needles don't get in a bind when you put the floats back on.

 

[hookedonjc]

Re: 120 evinrude still acting up

Ok I will check that also. where can I get the Berryman Chemtool ?

 

[hookedonjc]

Re: 120 evinrude still acting up

IS the Berryman Chem Dip the same as Berryman Chem tool. I bought the Chem Dip and it says no plastic so I just wanted to make sure I got the right stuff.

 

[Walker]

Re: 120 evinrude still acting up

yep, Berryman dip. Soak them about 30 minutes then rinse them with an aerosol carb cleaner with the little straw. Blow the stuff thru every orifice and jet you can find. Make sure the stuff sprays out somewhere else so you are sure jets are clear.

Joe - What is the reason for the .040 gap? My OMC books says .030 also.

Thanks.
