Yes I went with my 67 muscle car to Lucky 11 Hot Rods Nick Nichols the mechanic Does not even know how to tune a carburetor Why even attempt this stuff if you don't know how to do it.. I hate putting people down but just about not having someone else go through the same thing..I Didn't know if it was just me having these experiences but now im starting to read these posts and it makes sense..just be careful we all make investments in are classic cars and it gets expensive last thing if i was a mechanic is take a risk on someones classic vehicle just beware and be careful ..
