REFLECTOR: Exhaust systems

[steve korney]

John...

In that case your running way to rich...You should see temps of about 1250 
to 1300 (f) on take-off...
Maybe that's the reason it stumbles so much on run-up...Lean it out...Keep 
the temps above 1150 on the ground or you won't vaporize the lead in the 
fuel and it will foul your plugs...



Best... Steve
