I did the torch test,and came up zilch-no increase in engine speed,although I found that carb. base vacuum fitting,(brass nut),split. I held the torch to it,and it didn't make a difference. The carb.base has indents for the vacuum port,and they are lined-up."I'm crossing my T's and dotting my I's on this one"! "One thing at -a time' is very good advice,and can save a guy a bunch of time and headaches! Progress is being made,but to work it into my schedule...
