How do I adjust a Mikuni roundslide carb. Thanks

A model number is useful or even the 'friendly' name 'Fat Boy' 'Sportster', 'Street Glide' etc.

No it will not work.

Each carb has a small vacuum port on the side above the float bowl, you adjust the idle stop screw to set the tune and sync the carbs. Leave the air fuel mixture screws alone.

Why did you need to clean the carb? Routine servicing of the aircleaner would keep the carb clean for life. The pilot screw should be 1.5 turns out approx. with a small adjustment either way. Idle speed is set to a smooth low idle.If this doesn't fix it have you got something in the carb not replaced correctly? The float needle/float assy? How did you clean it? Have you introduced fluff/dirt into the carb and did you blow it clean with an airline?

My pw80 03 won’t turn on with Choke off or stay on with choke off

1 1/4 turn out from fully in

should be a mixer screw on carb.

Stens is an aftermarket company. might be able to get an aftermarket carb or kit there.

get the bike started, hold the engine at a high idle. while holding the idle high, adjust the air fuel mixture screw until it sounds smooth. rev it up a few times and see if the engine is "snappier". let it return to an idle, then adjust the idle screw. it may take a few tries to get it right, just listen to the engine.. if this dont work, you may consider re-jetting the carb. hope this helps...
