stihl 441 floods will not start

Is it possible the ignition can spark but not be hot enough or defective

spark must tested inside the cylinder not outside

Cant you take it out of the housing wind it in your hands and put a needle nose vice grip on it?

The carb needle valve stuck this is why the saw flooded

The saw has so much compression the starter hung half pulled I was trying clean every thing let stupid spring pop out I'll have give it another go I don't think a new one is much I got order those missing air filter parts and get a clutch drum last guy had a spur sprocket and it's wore slam out

That's works nicely, I just put a needle nose vise grip when wound, that method looks good too.

Looks like gas kept coming out and maybe ran out between carb and air box

Good that you find where is the problem for sure now you can repair it

Well it should be level with the carb body with the gasket off you cant just compensate by changing that if something else is wrong.. To answer your question If the Metering Lever height is set too high, it may create a rich condition, while a Metering Lever set too low may create a lean condition. Is yours level and does everything look in order? Post a pic of it while you are at it.

Is it an m-tronic carb saw?
If it's starting without choking it, then something is leaking after shut off to make the mixture rich.
Did you pressure test the fuel inlet?

Fuel lines are new and holding presure

No matter if the carb is clean and rebuilt , the carb needle stuck and the saw flood

Directly from the ms 441 service manual the two first reasons have to do with the needle

Condition Cause Remedy
Carburetor floods; engine stalls Inlet needle not sealing –
Impurities in valve seat or cone
Remove and clean inlet needle or
clean carburetor
Inlet control lever sticking on
spindle
Restore easy movement of inlet
control lever
Helical spring not located on nipple
of inlet control lever
Remove inlet control lever and refit
it correctly
Perforated disc on diaphragm is
deformed and presses constantly
against the inlet control lever
Fit a new metering diaphragm

Every thing seems to be in order unless there literally a piece of trash under the needle, I ultrasonic cleaned the carb and installed all new parts, I feel like banging my head on the wall lol

I have see this f..... ing problem in many saws , saws floods or boging just because the needle stucks , check again or try a new needle with metering level

 

[pantelis]

Also sometimes theese thing ( red line ) are more tight and metering level that keep the needle can't play free , check also for this
