Help! I am sick of this high idle.

I had to adjust the idle screw to get it to idle down. Under normal condition, where I turned the screw to, it would idle too low, and die.3 things quickly come to mind:
Idle speed screw turned in too far?
Throttle cable adjusted too tight?
Air leak?
it's possible that you have the carb slide installed backwards (or 180 degrees off). the slide has 2 slots in it, a short slot and a long slot.
the long slot goes to the right side of tyhe engine and lines up with a pin that's cast into the carb body. the short slot lines up with the idle screw on the lefdt side.
if you have it in backwards, the long slot will line up with the idle screw and make the idle screw do absolutly nothing.
the short slot will line up with the pin in the carb and the slide will not be able to go all the way down to the bottom of the carb.
this is such a common thing because people just think that the slide can go into the carb anyway.
it can go into the carb 2 different ways, but only one way is correct. long slot to the right, short slot to the left while looking at the engine from above.
soapy water isn't the best way to find an air leak. starting fluid is the best way because it will make the engine rev up when you hit an air leak with it.
I'm an electrician for an oil company. I know not to use silicone. I asked our mechanics for some shìt to use on my carburetor, this is the stuff they gave me. We use it on our natural gas compressors that are making somewhere around 1000 psi. It can be put back in service immediately as well.well, silicone is NOT the best idea to seal up a carb. silicone will dissolve when in contact with gasoline.
using silicine on the intake to cylinder gasket won't last very long.
the best way is to make your own gasket out of some rubber-like gasket paterial.
sealing the carb to the intake, you need an o-ring to go inside the carb throat to sit where the intake seats against the carb throat.
it sure sounds like you have a massive air leak, or, your cable is binding causing the slide not to go all the way down.
