[NSRCA-discussion] OS 140RX Need Help

[Chris Moon]

Main bearing.  No acceleration and loading up are classic signs.

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…???
