MS441C stalling.

[Gerbutt]

Hello all

 

I have an MS441C that starts and runs fine for around 15 seconds and then it stalls as if it’s running out of fuel. I’ve just fitted a new carb kit but it’s still doing it. Do you think it could be the fuel solenoid? Or any other ideas?

 

Thank you

does it sort of bog when you rev it then stall? 

 

my 150 was revving up, then would bog n stall

there is a tiny filter in the carb which was blocked, cleaned that and runs sweet again

Yeah it does do that but I changed that little gauze with the carb kit. The old one that came out was clean so think that’s fine.

You've done a M-tronic "reset" on it?

 

My 261C did similar. New solenoid did the trick.

Hi Bob. Yes tried the reset. I’ve ordered the solenoid so will see how that goes.
Thank you

Hope it works. 

Fiddly job but it did cure my 261. 

 

Best of luck.

Stalling is the key symptom of the solenoid failing. Fit the upgrade beige one with the new orange fuel filter. That will sort it!

It should work, just push it in carefully so the O ring doesn't get damaged.
