TimJ Posted May 19, 2011 Report Share Posted May 19, 2011 Just done a fresh rebuild. Mods are:Play port, v force 3 reeds, stock carbs with 360 main 27.5 pilots, noss head , 20cc domes, bills pipes, no lid on air box with k&n filter. I am at 750 ft above sea level. It idles fine and when you bring the pipes on it will scream but at low rpms both cylinders gargle. I am running 32:1 100 octane. My air screw started at 1 and a 1/2 turns I am sitting at 1/4 turn and its better but still doing it . My needle is on the next to the top knotch. Do I need to move down on the needle it was ion the middle and was doing the same. Please help? Quote Link to comment Share on other sites More sharing options...

I had almost the same mods, except t5s and open pod filters and i had 310 mains at 1500 feet. Im thinking you should be like a 320. Just my 2 cents Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted May 19, 2011 Report Share Posted May 19, 2011 A play port can mean diffrent things,certain builders play ports can be jetted as high as 340-360,if your 1 turn out an it runs better,try a 30 pilot,but b4 i would do that I would try richining the needle up all the way(all the way to the pionty side) Quote Link to comment Share on other sites More sharing options...
