How do you find and clen the idel jets in carb on a poulan 2150 2.1C.I

Spray a little carb cleaner or brakeclean into carb w/air cleaner removed. If starts, check fuel supply to carb. If ok, clen carb and jet with spray carb cleaner and try again.

No idle jets. this is a diaphragm carburetor

Hi dennis
Sounds like to me that you have a problem with the high speed circuit of the carb...could be some trash in the jet or the jet may be out of adjustment...try adjusting the jet and try to go to full throttle after your adjustment

clean the jets in the carb

I expect you have blocked jets in the carb.
Strip down the carb and clean the jets then reassemble and tune.
Hope that helps.

You can try draining the carb and cleaning the main jet first?

If the carb is a bowl type also check the float to see if enough gas is flowing when the float hangs free. The carb should stop flowing then the float is lifted up and is sitting parallel to the carb body.

If you dont have a float type carb you can remove the carb body and check for dirt in the pickup tube as well as the main jet.

You probably have a partially blocked main jet inside your carb!

You need to pull the bowl of your carb and snake the main jet with a fine piece of wire *( a stripped twist tie is usually enough).

You might not have the type of carb that has the main jet underneath.
You need to run the model number on this unit and find the parts breakdown for the carb it has to locate the main jet.

Good luck and be careful.

Sounds like a problem with the main jet. Make sure the carb is cleaned of all the gunk from old fuel. Idle jet ok but if throttle opens too much air will kill engine if the main jet is blocked.

Either the spark arresting screen is clogged with carbon, or the carb is out of adjustment on the high speed jet.

hi jay,,if u r having to use the choke to keep it go ideling , then either u the idel jet is blocked and will give u fuel starvation ,so usin the choke the main jet has to force fuel in 2 the float chambers,, at the bottom of the carb,, so firstly remove bottoms of carbs and one jet at time take the needle jet and main out , u will see little holes on the needle jet.or needle guide jet if u like, poke a pin in the holes ,and blow threw till u see light threw them, give every thing in the bottom carb a clean while u r there, then replace that jet and everything else ,,then move to the next carb and repeat the process,,put carbs back on the bike, then air boxmake sure theres no air leaks between air box and carbs ,, try that matey,, hope it helped,,
