Serial C187V13827S

This is a strange problem to understand.

Have been working on electrics for the past 6 years, so learning Internal Cumbustion again.

After 5 minutes of run time, engine won't rev up when the gas pedal is down to the floorplate.

It starts fine and idles good.

I adjusted the Air-Fuel mixture the way that is described in the Maintenance Section, Power Mixture adjustment did not make a difference.

Removed cover from the Vaporizer, very little tar build up and the components look good too.
