Fresh rebuild on jlo 295. Now have fuel coming from exhaust while cranking. I am getting spark but not sure if it's enough. I know I don't have the correct plug(ordered). Is there anything else I should check or can it be as easy as a new spark plug?
Check your timing. When you are cranking the engine hold your hand over the intake and see if the engine pops. I have had this happen plenty of times and timing has always been the problem. These things are tough to time sometimes. Check the gap on the points too.

Points gap is fine. Unsure of the timing. I haven't found an easy way to check it. Even if the timing was off I would expect it to try to run. This one doesn't. I assume since fuel is running out the exhaust that the carb is doing it's job. I'll try to find a way to check timing. I have a JLO engine manual but I don't have that kind of timing light. Only one I have is automotive type.
Did you try holding your hand over the intake while cranking it?

lots of plug fouling issue's with these motors,try a new plug. not sure why but the ignition system on these are fickle.(even when they were new they fouled lots plugs)
if the electrical worked before the rebuild and an new plug don't do the trick, it could be timing.
mine will not run at all when its flooded make sure the crank case is not full of gas.

My new beer holder spilled some on the trails - in it's hair and down it's throat.
Joe Camel never does that.
Advice is free, it's the application that costs.
Held my hand over intake. Did not pop. Should have new spark plug to try tomorrow
Here is how to make a timing light, they are really simple and only cost about $10.00 to make. Just make sure you buy a light with a bulb in it, no LED. You can get a dial indicator cheap at Harbor Freight.

I did make a timing light from a 12v battery, some wires, and a light bulb. Seems to work fine. Just need to find a sial indicator. It appears to fire just before TDC just not sure of the exacts.
Yea, you are kind of in the dark without the dial indicator. They are cheap though.
