Ok i just replaced my air filter, spark plug and fuel filter and now it seems like it will run on full throttle but stalls on idle or low. Any thoughts………thanks

your low speed circuit is restricted , spray some carb cleaner into it . Always add fuel cleaner into your fuel routinely !

Thx for reply. i do use sea foam. i ended up buying new carb because i got frustrated with old one. i claened the old one to no avail.

new carb does same thing. it will only run on high. as soon as i release trigger to idle it stalls

Your low speed jet controls off idle performance . Ensure it is set 1-1/4 to 1-1/2 out from gently seated . Another possibility is that you have an air leak . Carb flange loose or gasket cracked , gas line cracked or crank seals worn . Inspect to determine !
