black sunshine Posted September 28, 2009 Report Posted September 28, 2009 it also has a 270 main jet but i am unshore about the pilot i have to buy a screw driver tomorrow Sorry to laugh, but the scewdriver part cracked me up! Sounds like you may have an airleak. Do a leakdown test when you gett'er back together, then run some plug chops to dial in your main jet. Quote
