Try that out

I would make sure that you have the proper gas/oil ratio mixed first. If that is ok then I would have the filter changed. If that doesn't solve the problem then you should take it in to have the carburetor serviced.

How old is it? Does it show a spark when you remove plug an hold against engine while pulling cord? Did you replace plug? It is the most common problem. Remove the stop wire an try to start, if it does or you see spark the switch is bad. I would check put these things before replacing module.

After removing the 4 screws and clutch cover you should be able to pull the clutch assembly off with a gear puller.

I have the exact same problem, new carb, new coil, new gas. I think it is not building enough compression to support combustion.
Won't even pop starting fluid !!

clean the screen inside the muffler

Spray starter fluid in the air filter. This should work.

I have the same model, I inserted a large screwdriver on the inside to stop the rotor assembly from spinning, then I used a pipe wrench (but channel lock pliers would probably work better) and then w/o much effort, I easily turned the wrench counter clockwise to loosen.

Hi and welcome to Fixya. The symptoms your describing are typical of what happens when the engine experiences fuel starvation.

It can be caused by a clogged fuel filter screen located at inside the attachment point of the fuel line manifold on the carb. Turn off the fuel and remove the mounting bolt for the fuel mainfold. Very carefully remove the plastic screen inside the manifold and clean off the debris that has built up on the screen.
If the screen was visibly clogged you probably have solved your problem. Just make sure you re-install the screen when re-connecting the fuel line manifold.

If the screen was not clogged then check your fuel lines for cracks. Air being introduced into the system will cause the same symptoms you describe.

If the problem persists then there is the possiblility that the needle and seat are partially blocked inside the carb itself on the bottom of the carb body after you remove the bowl. (Usually not the problem) However the bolt that holds the bowl on has 1 or 2 holes in it that can also clog and they must be clear.

And finally there is a BRASS jet that unscrews with a screwdriver in the bottom of the long draft tube (way below the throttle slider / needle) that gets clogged. Unscrew the brass jet and force air from the threaded end to clear the orifice.

By this time you probably figured out the float comes off with the bowl. note which side is UP! Also DO NOT adjust the float level it is preset. u|Unless you bent the float control arms it does not need adjusting.

Turn on the fuel... and start the unit after re-assy and it should run just fine. You should be tilling real soon!
