Can anyone with a black engine Beamish please tell me the size of the pilot jet

they are running in both the 250 and the 325?

The manual suggests that the 325 should have a pilot jet of 20 and the 250 a

pilot jet of 27.5 - that doesn't make any sense to me if the larger number denotes a larger jet - would you have the smaller jet in the larger engine? I have a 250 and have just

stripped the carb, the jet number is too faint to read.

I also have a 325 that was originally a 250 and that has a 20 pilot jet and it is not

running correstly.

I would also like to know the needle clup position as counted down from the top

of the needle.

A concensus of what people are actually running might tell us the correct

answer and prove the manual right or wrong!

Merry Christmas to you all!
