Fine tuning old and irrelevant carburetors that no one makes parts for anymore and having to ream little holes in brass tubes to get the mixture I want at different loads. I don't know why I put myself through this, but I can say I'm one of the best Solex carburetor tuners in my area. I don't even have a shop, or work in the field at all.
