adjusting propane mixture

[mckeddie]

How do I go about adjusting the mixture on my Propane setup?I think its running rich. Im going through 20 lbs. In just 2hours of run time on a 22r with no real obstacles to speak of, just putting around main trail mostly. I want to try leaning it out. Its a gotpropane set up id that matters.

I know nothing about Propane.

This link talks you through the main steps.

The main mixture valve should have markings that say R and L (Rich, Lean). Adjust as necessary.

Don't go to lean though. I was a bit lean one run and the exhaust got so hot that it turned a red cherry bomb half brown:eek::rolleyes:

Pretty much all of the gotpropane stuff is impco brand
