89 marathon won't turn over

[Bradcfromnc]

ok as a newb im about to pull my hair out. 89 marathon with 3pg engine new wiring battery solinoid and verified accelerator switch works bypassed neutral safety and reverse switch. I push gas solinoid clicks but starter generator won't spin i bench tested starter solinoid and it worked also has new bushings. Need ideas and help

Have a multimeter? Check to see if you are getting 12 volts at the starter, then check to see if you have ground at starter. You must have both for it to work.

Got it running in forward and reverse just not in neutral guessing thats just how they are

[newtjl]

Yes, the two strokes are just forward and reverse. The switch actually changes the direction of the engine.

Another question the carb has a small shaft with a small hole sticking up near the throttle lever how do i plug it jb weld? Its spitting out of that hole when I'm running it now

That indicates a problem with the carb. If you plug that, it will either flood the engine or the bowl on the carb wont fill. It is a vent. Does it run well otherwise? Sounds kind of like the needle isnt seating in the carb. A simple float adjustment may be what it wants. That shaft is actually is a nipple for a small rubber hose. Just putting a small hose on it, about three inches long may take care of the problem.

Is there a specific measurement for the float level? I just ordered a new carb also any info on tuning one of these cabs would be great

[newtjl]

The new carb will be factory set. They are usually plug and play.

You are better off using parts from a new carb to rebuild the original miking.
As for float adjustment you just hold the carb upside down with the bowl off and the float should sit level. If it doesn't adjust the tab that sets aganist the needle.
After that's done make sure the throttle plate shuts fully and adjust the air screw all the way in and a turn and half back out. Adjust from there.

I had this issue, it means your jets are clogged. Fully disassemble and clean, took me three tries getting it cleaned fully.
