If the carb was real dirty you might have missed the low speed jet.It's usually a VERY small hole in the main jet.If you don't get this clean it won't run right.The air screw should be turned in till it just stops then out 1 turn then adjust as needed.J

i cleaned that jet but set it back to 7/8 open because thats the way it was. but i will try it at one full turn.
thanks bob,


hi i just bought a 55 hp chrysler 1973 outboard on a 1971 bass bomber and it was running but sputtering at idle. cant seem to get it running and stay running so i rebuilt the fuel pump and then tried to start it. it started and stayed running for about 7 minutes. Then it shut off and i could not get it started again. I also rebuilt the carb. i set the air jet to one full turn out. i am getting spark from the spark plugs but it will not fire. i put in new champion L82c plugs and replaced the fuel lines. now i cannot seem to get it to fire at all. i also took off the fly wheel, regapped the points, and still cannot get it to start. i'm not sure these are the right plugs maybe i should use L20v?
is there any ignition switches, breakers, condensors, or solenoids that may be weak or stopping the motor from running? if so, how can i check it?
Any suggestions, would help greatly. We are leaving Thursday to go to Canada fishing and really need to get this motor fixed.
Thank you for your time.
Duane

Thanks for all of your input. We checked the coils and found they were extremely hot and cracked, replaced them, put in hotter plugs (L86c). Smokes alot but maybe running to rich of fuel (50:1)? Should I run 40:1 through it? Anyways starts up everytime thats the main thing. Thanks again, everybody was helpful and now were off to Cananda Friday morning.

Re: 55 hp chrysler 1973 starting problems

50-1 is the way.Too little and it could sieze,too much and it will carbon up and ruin the cylinders.Take along another set of plugs when you go to Canada.
They would probbaly cost $10 each up there.J
