Carb Idle change in hot weather
I noticed my carb idle has decreased about 250 to 300 RPM since the weather has gotten hotter. Its a throttle stop carb and im wondering if I should just adjust the idle or mess with jets and bleeds, or adjust 4 corner idle screws. Dont wanna open up a can of worms though.

4 corner idle screws seems appropriate. Need to lean it down a little bit to counter act the hotter/thinner air. Then the idle adj. as needed. Just do one thing at a time and know where you started.

if the idle was fine previously, then turn the idle mixture screws in 1/4 to 1/2 turn.
