EXH/EVG Family KE8XS 0775CF (Not sure if this is helpful)
Serial: 54894800121119
Another number on the machine is: 9999450128
76.5cc
This runs well 90% of the time. The owner reports this procedure:
Prime, choke, pull twice and it starts for a second then stops. Choke off, pull and he's off to the races.
Occasionally, it's prime, choke, pull twice, start for a second, choke off but then nothing. It won't start no matter what he does at that point.
The last time he brought it to me, I was unable to replicate. It started and ran fine for me every time.
Came back again after the same symptoms and I'm now experiencing the same thing.
The compression is 120. No carbon buildup. It just pretty much floods. The plug comes out wet.
This machine is less than a few months old. He purchased new and uses it commercially. Not sure where to start. I inspected the cylinder through the exhaust and with a scope. Everything looks ok.
I checked the spark and it looks pretty weak to me. Almost intermittent. But I'm not sure what it's supposed to look like. Is that a common failure on something so new? Every time I go chasing spark on one of these 2 strokes I'm talked out of it. Plus, it's almost brand new. But it certainly feels like a spark issue to me. But I'm no pro. Any guidance is appreciated.
