Answer 1

Best check the exhaust as the jet will flow plenty of fuel> Pull the plug an see what it looks like> If black on the outside ring running rich>If gray on the outside it fine>Most time the exhaust is restricting the flow>

Answer 2

just take the carb off and soak it overnight in berryman's chemtool b-12 & put it back on.

jets don't wear out, but they get gummed up after awhile cause gas turns to varnish as it evaporates.
