Hi I'm Wayne

I will help you with this

with the motor warm and at idle

turn the screw inwards until the engine starts to slow down

then back out the screw about 1 1/8 turn , until it runs smooth

if this does not help,you will need to rebuild the carb

or add 2-3 oz of a product called SEAFOAM, works very well

run that in the gas it takes about 15-20 min to clean it out

you can get it at any auto parts store
