I rebuilt the top end on my 1980 Yamaha LC50 Champ with a brand new PW50 60cc big bore top end kit and a new PW50 carb .
I used the PW50 top end to get rid of all the crazy vacuum auto choke BS.
It also has a new magneto and ignition coil and tested my CDI on a friends running Champ . . so it is not a spark issue.
It also has 120 psi compression with the new top end kit.
It seems to be wet fouling the plug after several kicks to get the fuel to the cylinder.
I reopened the top end .
Drained the small amount of fuel out of the case .
Dried it all out. Put it back together.
After many kicks I get it to start and run for about 10 seconds.
Then it dies and won't start again.
Pull the plug and its wet .
The knock off PW50 carb I bought off EBAY doesn't have any markings on the jets so hard to tell what size they are.
Any jetting/ carb tuning suggestions ?
