How have the plugs been looking?
I believe that in one of your earlier replies you had checked for leaks. Did you spray around the carb base and the intake with WD-40 or brake cleaner or even water ?
I checked the plugs a couple times and they were really clean.
I checked for vac leaks by spraying wd-40 all around the carb and intake while it was running, and it made no difference (except made things messy). Then I also tried spraying starter fluid all around and the only time the rpm increased was when I got some in the carb.
But I know what your sayin Harvenator - it sounds like a vac leak or a lean condition. Thanks for your input. I'm still placing my bet on carb problem. Will let you know in a week or so when I get my new carb from DemonSizzler...
