Hi Tyler and Norm,
Max, I thought that removing the brass jet was to make them leaner for high altitude operation
I thought it works the opposite way Tyler , the bigger the air jet the more air pressure makes it's way down to the main jet which along with the vacuum acting on the main jet this helps to drag more fuel from the main jet , the air bleeder jet will mix air with the fuel but I thought it's main purpose is to help the fuel to be drawn up the main jet.
At high altitude I would have thought you would go to a smaller jet.
Max, I probably have about 10 here now all doing the same but I am not game enough to pull the one working carby I have. And this is a carby I have not put a kit in. I guess I could go to the local mower shop and get a kit from them to see if there is any difference in the ones they have
There could be a problem Norm with the kits if they have shrunk or are cut wrong ,maybe worth getting a kit at the
local mower shop just to check.
Cheers
Max.
