You using low octane fuel? The VTX was designed to run on the lowest octane and using premium is known to foul the plugs

Maybe the float valve is not shutting off the fuel flow.
Could be trash.
Could be incorrect jet.. What size main jet?
Could be over oiled air filter.

You could be getting more spam mail by having your email shown.
See if the ADMINs could change that.

Always start with the easy, inexpensive fixes first.



Check that the choke (Enricher) is fully closed.
They've been known to work themselves open after a time.
