hercalmighty Posted February 17, 2009 Report Share Posted February 17, 2009 Try dropping down to a 25 pilot and see if that clears things up. Quote Link to comment Share on other sites More sharing options...
mesa banshee Posted February 17, 2009 Author Report Share Posted February 17, 2009 even with 350 mains Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted February 17, 2009 Report Share Posted February 17, 2009 Acutal your main seems a little high too. I would maybe drop down down to about 320. How does it run up top? If it starts hard change the pilot. Pilots control idle to 1/4 throttle. Quote Link to comment Share on other sites More sharing options...
mesa banshee Posted February 17, 2009 Author Report Share Posted February 17, 2009 runs great up top Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted February 17, 2009 Report Share Posted February 17, 2009 if it runs good then just try popping in the 25 pilot and see how it goes Quote Link to comment Share on other sites More sharing options...
01banch Posted February 17, 2009 Report Share Posted February 17, 2009 (edited) being rich on your mains usually makes it start easier when it is cold then harder as it heats up. Edited February 17, 2009 by 01banch Quote Link to comment Share on other sites More sharing options...

screamin_banshee_2003 Posted February 19, 2009 Report Share Posted February 19, 2009 for the main thats way high I was running 350 jets witha 4mil ported eng on the stock carbs If u are running the pods filter that hook up to the carb u should be around 300-320 Just removed the cover of the airbox I would say 290 or 300 The elevation and temp also plays a roll in jetting For temp. When it is cold u go up a size on the main jet ... Warmer down a size Goin 2 higher elev. Drop a size.. Goin to lower elev go up one size If it is hard 2 start change your ngk plugs. Ibet they are blacked out and soaked with the fuel mixture Quote Link to comment Share on other sites More sharing options...
