Im still thinking carb issues, just cause I triple checked everything several times on mine and had my carb apart a dozen times before the gunk worked out of one of the passages. When you had it apart did you blow all the passages out with compressed air?
I melted a coil by not having the resistor on it once, Oops...
Now a question for the carb gurus, I thought a rochester would be to small to run a 270??? :confused:
