Thanks for pic WayneJ.
If this is the tube that sticks up in the carb, the nozzle, that that main jet screws in to, mine is broke.
On your pic, there is a hole at top. Mine looks like it has broken off at the hole. Half is there and half is broke off, I guess.
When I tried to take main out BOTH brass pieces turned and did not come out. Will try harder tonight. That means something else will break.
Thanks again for pic.
Worlds worst mechanic
