    Do you have a 18203 model ? ? ?

    quote BillW:

    I thought there was a pretty good size air intake hole right under the carb, just above the shift cable attachment bracket…?

    I see that now. Thanks for clearing that up. I’ll feel better now about closing up some of the gaps I have around the choke knob, mixture knob, etc.

    My needle valve kit/bowl came in the mail today. It’s in A LOT better shape than the other bowl I tested last week. I didn’t realize how badly corroded the one I tested last week was until I saw a brand new one (NOS) today. There is quite a bit of aluminum missing (corroded away) in the high speed orifice area of the one I ran last week.
