New guy engine problems?

[Doug Ashby]

Hello all:

I was bench testing one of my 1/8th scales and could not get it to start.

What I ended up with was a pipe full of nitro and a puddle under the engine.

I'm probably overlooking the obvious, but go ahead and tell me what you think is wrong.

It's a CMB, had a new plug that was warmed up. When I took it apart to clean up I noticed the low idle screw was all the way down, and the remote needle was open about 4 turns.

Is it possible to over-fill the tank?

Wow, sounds like she's really rich & just flooded out big time. Stock carb??

Yes. It is a stock carb. So how do I lean it out?

bring your HSN to about 2 1/2 turns.

I did that one time. Reassembled the motor with the piston in backwards (the cut out in the piston skirt facing the exhaust port.
