Made me say hmmm too... because this is part of the problem I am having....I noticed last night a nice cloud of smoke at part throttle....not off idle, not at WOT...but....right where I said it was bogging and running funny.
If I run the screws in it barely runs but will not die....
Going to nurse it till payday. Then I will go buy a new valve...see if that helps...if not I am going to attempt to rebuild it.
If you can leave two black stripes from the exit of one corner to the braking zone of the next, you have enough horsepower. - Mark Donohue
