Yes I noticed that noise and the unhealthy looking dribble of fuel that flows from the front bearing when the engine is too wet. It doesn't seem to adversely affect the engine's performance. The Moki is one of the best (ease of starting, power, idle, transition) engines I have ever had the pleasure of using. I guess that we just put up with a little mess and that sucking sound from the front bearing.

On a different topic, are people using the Moki gold plug that comes with the motor? I found that it requires a lot of current (4amps) to get the engine to fire - not a bad thing just an observation. Probably because the actual element is quite a bit thicker than my usual OS#8. The Moki plug is giving me very reliable long idle periods (tested to 5 mins) with instant transition to full throttle, plus good RPMs (over 8400 on Bolly 19x8) on 0% nitro. I hear so many people prefer the OS FS plug - why?
