[NSRCA-discussion] OS 140RX Need Help

[Lisa n Larry]

I'm trying to get a plane going to make the Quincy, OH contest next weekend.

 

When running at idle or the engine isn't running, fuel leaks out of the
carb. I can get it started, but loads up in about ten seconds and bogs down
and dies when increasing the throttle.

 

If I pinch the fuel line, it leans out and recovers. As long as I stay near
full throttle it's fine.When at half throttle and lower it will bog down..

 

HS needle is at about 1-3/4 out leaned from about 2 turns out. I don't know
the pump settings.

 

This is a used engine already installed in a plane.

 

Is it just a matter of the pump pressure being too high or do I have other
problems to deal with.???
