RE: bme 110 and carb problem

A pinch test on a gas engine should not give any information that I am aware of.
You need to lean the engine so that there isn't a hesitation from idle to mid-throttle.
Just keep leaning until you get the hesitation then back off.
With my BME 100, I close the throttle and adjust the needle to get a reliable idle, good transistion, and no real issues on extended down lines.

Note: I do have mine set rich right now. I changed oils and will be leaning my engine as time permits.

I have a carb that runs rich on the low end. I can get the needle into 1/8 of a turn out and it will still climb 500 -600 rpm when pinching the fuel line closed.
I think it is the pop off pressure but not sure.

I was told it should pop at 10-12 and reseat at 5-6 psi.

any help?

Jim
