your high idle may be caused by a vac. leak?

Charlie, I have looked and changed and tightened everything I know to do. However the new carb does have several vacum ports that I had to block off because of not needing them so it's gonna take someone with the ability to find it cause I have looked.

thanks,
Em

"Look" with a can of carb cleaner! Spray carb cleaner around all the intake mating surfaces, carb fittings, etc, etc and if the rpm goes up you've found the area of the leak. Then some selective spraying can isolate it to a specific item leaking. Just a thought....

thanks Roger, that will be my next move but it may be Tuesday before that happens - - - - grocery day tomorrow - - - YUCK !

I hope it doesn't turn out your vacuum leak is at the carb base/intake manifold where I suggested Permatex (Form-A-Gasket #3).

Not more than 2 minutes ago my wife said something poignant about the fact that "we" haven't done the food shopping yet this weekend so my first reply was "we don't need no stinkin' shopping" but I don't think she liked that one.

Got it cranked - - - idling at 1400 rpms - - - let it run until choke opened and then sprayed starting fluid around the base gasket - - - "voila" it sped up so I've got a leak there for sure - - - - next move is to NAPA for new gaskets and maybe some "stickem"????

Em,
You really don't want any type of "stickum" on a carb base. If everything is flat and clean the gasket will seal. If it's not clean, clean it and scrape gently with a single edge razor blade being careful not to gouge the surfaces. If it's not flat you need to fix that by surfacing the faulty part. A good surfacing block is a piece of glass with some fine sandpaper on top. If you research the carb to intake joint you'll find that clean and dry is the way to go.
