MS170 having problems

[hedgesparrow]

have a ms170 been a very good saw but of late has been playing up hard to get going after its run out of fuel. when it does get going have to feather it to get it run smooth. today it just stopped and will not go. tried new plug good spark fuel is coming through feels like it has got compresion. but it will not start. checked filter in tank fine clean air filter is clean. at a loss what it can be apart from the carb needs a service, or it has some thing wrong on the engine side. like to try and get it working even as a spare. as got a second hand one which chain brake gone so swapeed over to that saw.

any help apreciated

If it has a exhaust screen under the deflector on the muffler check that.

Have to burn the oil/carbon build up out of mine twice with a torch.

will check that does get very smoky after running for a while anything is worth a punt

If problem persists, sell it (honestly described) on ebay with a part worn bar and a part worn chain for £100 and get a new saw with a new bar and new chain for £170.
