well if your going to scrap the carb, go with the kehihn pwk39. i am in the market to get a new carb and from the suggestions i have gotten on here, thats what everyone is recommending to me. just over 300 thru dennis kirk. the intake boot might be a bit harder to come by, look around on ebay or post a want to buy ad in the classifieds, maybe some one on here can help you out. i had the same problem with my intake boot be dry rotted, alls i did was went to the autoparts store and got a can of the stuff you dip your metal plyers in to give them grip, i used a small paint brush and coated the entire outer part of the boot. worked awesome, no more leaks, and it still looks stock.

Life's journey is not to arrive at the grave safely in a well preserved body, but rather to skid in sideways, totally worn out, shouting "HOLY SH-T, what a ride!"
