[NSRCA-discussion] OS 140RX Need Help

[Lisa n Larry]

When I get it lean by pinching the fuel tube it will transition ok until it
loads up again.

 

Is this consistent with the main bearing. I have a set of bearings to
install if needed.Would rather not, unless this is the cause.

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.???
