Hey Gang,
I know there are so many threads out there for troubleshooting and it typically boils down to the big 3.
However, I have all 3 and still won't even get a pop.

This is actually an old redcat atv, 3 speed, estart. It ran before putting it away for the winter. The wiring was a hack job before and I couldn't get it to fire when I pulled it out of storage so I replaced all the electrical.
I've got the E-start turning, switches all working, getting spark when I ground the plug against the case, checked the ensure the mortison key is in-tact and TDC lines up for timing, checked compression and got 110 psi regularly.
I have tried getting it to even pop through the carb and with starter fluid through the carb, in the spark plug port, and straight into the manifold with no luck.

In digging through some archived posts, there was brief mention of getting spark on the case but not once it was threaded into the port but I never really found good reason for this.

Any thoughts?

 

"there was brief mention of getting spark on the case but not once it was threaded into the port"

I'm deeply suspicious of anyone who claims this as, how do they know? Briggs & Stratton made a tester so you can check how good a spark is, but I have been amazed at how some engines run with the freeblest spark, Suzuki LT50s never seem to have a very bright spark, but run fine. Others, despite sparking at the plug OK, won't start, but will if you change the plug. You may have seen my reference to using LPG from an unlit gas blowlamp, in other posts. This doesn't "wet the plug" like starting fluid or choke does.

 

Wow. I've never had an engine with spark not respond to starter fluid before. I have a propane torch ... I might need to do some googling before I start blowing gas around there haha.
I pulled carb and checked all the jets and all is clean as a whistle. I haven't worried much about supplying just standard gas to the process as opposed to starter fluid so I'll tinker with that and roll it over a bit.
I took a little video of the spark. It is medium strong I would say and pretty fast though. I figure these just let it spark at each rotation than compensating for just the ignition cycle. Sound right?

 

"I figure these just let it spark at each rotation"

Yes, they are so called "dead spark" engines. Regarding safety, squirting gas into the air intake or carb is just like squirting starter fluid in, don't overdo the amount, the blowlamp will have a control valve on it.
