Re: Carburator replacement 81'gas
For carb, just do normal fuel and air mix adjustments after it is installed. check carb base gasket for leaks after it is running, with some wd40 or carb cleaner or something to see if the motor rev's up- which means it is leaking.
also, be sure to adjust timing as well.
Just buy something like a 30 dollar electric tach on ebay.
If you go and buy a low pressure electric fuel pump from the parts house - a generic one - you can put it inline in the fuel line, and when your mechanical one goes bad, or you want to pump gas to the carb while checking it, you just turn on the electric one. They usually cost less than $30, and ya gotta wire in a switch or have it hooked it ig on position. I imagine the bus takes a 8-10 lb one or so... dont buy or use something like a 40-60 or so lb one which is made for fuel injection systems.
An aftermarket air cleaner will work fine, and be less bulky than the stock one.
just my two cents worth.
