Frank:

Pardon the delay in this reploy - I was down with a virus. Had an email come from a known correspondent, but it wasn't really him. THe virus was PE_BAGLE.N and I'm finally up again. Have you ever attempted data recovery from a 150 gigabyte system? Or worse, had to pay for it? Ouch!

The bit on overbore of the carb is when the hole is bigger than the remaining land on the barrel, there's not enough barrel left to close the throttle all the way. If you can shut off with the trim, you aren't there so don't worry about it.

Your idle is still rich, leading to the loading up you're getting. This is shown by the rpm rising when you pinch the line. If you were at optimum, the rpm would hold for a cecond or three, then fall. Or if the rpm falls immediately you are on the lean sode. and you can then turn the screw back in to richen it a bit.

Bill.

PS: Short, I know. I have 97 RCU emails piled up. Sorry. wr.
