Chainsaw rope very hard to pull
Ive had my ms290 for 14 years no problem and this just started. Pulls easy with plug out but you have to fight to pull it. with plug in. Was able to start it then could not restart.
Now it wont start at all but still pulled and jerks very hard. Pulled muffler off..ok..pulled flywheel off..ok..and by the way it does not have a compression release. I realize you have to tug on these saws but this is something that still has me scratching my head? Any ideas would be great. I want to save this saw. -- For full context, visit https://www.homeownershub.com/mainte...ll-824350-.htm |

I was going to say that ... chances are this is a homemoaner who uses the saw to trim a couple of branches a couple of times a year . And it's never been run wide open since the day it was new , and "if one ounce of oil is good 2 must be better" . I'd bet that piston has enough carbon buildup to jack the compression ratio pretty high . -- Snag In 1775, the British demanded we give them our guns. We shot them. |

Timing is off and it fires at the wrong time. |

Chainsaw rope very hard to pull
If I install the spark plug by hand as thought as I can it will run fine. But if I put a wrench on it and tighten it literally a hair more it locks up. DONT GET IT!
Of all I have read here and on many other websites, the closest I have to an answer is "If I install the spark plug by hand as thought as I can it will run fine. But if I put a wrench on it and tighten it literally a hair more it locks up. ..." I am going to try to loosen my spark plug, LOL May let you know (If I can find this webpage again?) :-) I cud understand if wrong 1/2" reach plug that should be 3/8 reach and "barely" touching piston top w/ carbon? Or if "plug thread leakage designed as compression release port" LOL -- For full context, visit https://www.homeownershub.com/mainte...ll-824350-.htm |
