Hey all, just finished working out a weird problem with the throttle acting really erratic. Pretty much rebuilt the clutch stack and the problem went away. However, now, even with the engine tuned perfectly, there's a considerable amount of fuel dripping out of the pipe, especially on spool up and idle. The low end does not seem too rich. Here's my setup

OS 50 Hyper
Wilcat 30
Bobby Watt's Pipe
1.25 turns out on high end

Any advice on this would be appreciated.

Thanks.

Check carb is seated correctly and the O ring is in good nik. Also check for anything else leaky, head bolts and so on.

i've seen this happen in colder weather(less than 40F) on the first start of the day. goes away on subsequent starts after the engine was warmed up.

the other time this happens is when i overfill the tank and it spills into the muffler through the backpressure line.
