my new project is having spark issues.
 

got an 1983 ezgo marathon I'm working on with a rebuilt motor., stock carb getting gas out of the exhaust tried putting in a new coil/ ignitor and a new solenoid and key switch... have tried starting it with a spark plug see thru tester on it to check the spark going to the plug, glows lighter orange but won't pop..any :angry2:ideas to get a good spark to it so it will start???

Look through the exhaust and move the piston up and down. If you see a square hole in the side of the piston, it's in backwards.

I had that happen to a Harley cart brand new piston and jug trash because of that mistake so be careful when turning it over

Check the read plate and make sure it is not damage and that it is not just letting it dump gas in the motor that’s probably not the problem but check because they are fragile and can bend easy

Any More Ideas?????:thumbup:

Check the fuel pump for a ripped lower diaphragm. Did you check the piston? What is your compression?

New fuel pump...:thumbup: will check the piston this weekend.:mrgreen:

I wouldn’t crank it anymore than you have until you can verify it’s installed correctly. If it’s backwards it’ll wreck the cylinder, rings, and piston in a hurry.

piston is in correct..kinda figured out that the contacts on the direction shifter is not making a good clean connection so not much battery voltage getting to the engine/spark system..:wink:

:? still having issues new contact board and cam....same not not enough spark to start it. the only time it will pop is when you wiggle the Fwd/Rev. switch/ contacts..this weekend have to check and see what the pulsar ohm's at...?????????:cry:
