Champion RJ19LM. Just remeoved it from my snowblower. Measured gap as .030"
if its a snow thrower, when you are in operator position, it's right in front of you down left.
It should have a remote primer attached to the blower housing. in most cases it is held in place by three head bolts at the top and two bolts on the bottom of the sides. Remove it taking care since the hose from it to the carb is there also. The hose is worked loose and then there is probably a nut holding it in place.
