MS201 Top handle problem

[thecaptain]

Have had this ms201 saw for a few months now but have encountered a problem.

 

It starts ok, and runs ok, but after a few minutes use it will cut out,then impossible to start again, I have to leave it for 5-10 Mins and restart using cold start procedure.

 

Any idea whats causing this? not air filter as I just put a new one on

 

Thanks in advance

Could be a blocked tank breather. Next time it does it open the fuel cap and tighten it down again to ensure theres no pressure in the tank and see if it starts then.

Otherwise chances are the gauze filter inside the carb could well be choked up with grot.

thanks ill try that

 

anyone else confirm the above or provide a different approach?

The piston may have nipped up slightly and the lowered compression when warm may be giving issues.

 

It may just need a retune of the carb. If it is months old - get the dealer involved as it will still be in warranty!

What spud said, get back to dealer... But also I had a similar problem with a blower, it turned out the ignition coil had taken a knock. I put a new one on and it's as good as new.

A too large flywheel to coil gap can produce a spark when the coil is cold but will fail when hot and then be OK again when it cools - had a MS460 like that once. Also coils can fail when warm/hot!
