I don't know where they come up with it???
Everyone has their own ideas.
Has anyone seen where you can buy a main jet for one of these carbs in assorted sizes???
I think I'll just drill them, its been working for me. I think I'll go to the shop and abuse a few main jets
solder them then drill them bad ol main jets.
soldering them and redrilling to a different size IS trying to upset the mixture either more or less fuel.Right???
Just how does that hole get there in the first place. magic? do they buy a box of assorted holes?
