ive got a new tilly 304wx on alcohol on the engine, its got three weekends on it, i'm still having trouble getting it to take off on starts, still wants to stumble, low side is about 2 3/4 out, high at 1 out, how much more out can I safely go on the low side before I run out of threads? ive bumped the idle rpm to about 3100 which helps on the starts, except when everyone gets jumbled up and I have to slow down/hit the brakes momentarily...im gonna say after the build was all said and done, the motor is probably something a little more than a typical "limited mod", but not necessarily a flown blown open, is maybe the 304wx not enough carb? is there a model of tilly that might be better for my motor in anyones opinion? THX!
