MS 250 Very hard to pull wont start!!
« on: January 08, 2014, 08:47:29 am »
I used it about a month ago with no problems and then took it out this weekend to use and could barely pull the chord.  I took the plug out same problem, put some sea foam in and let it soak pulled again without the plug in same result.  I took the starter off and it is free nothing binding. I can turn the flywheel by hand easily as well.  I took the muffler off to inspect and do not see anything glaring. 

Any ideas?

Mike

Maybe it is cold?

Thought that myself it is cold here in south texas but not that cold.  plus the starter spins free when removed and the flywheel as well.

I have a latter 025 and a MS-250 and though I have not started one since around Christmas, I have not experienced this hard pull phenomena.

You didn't mention if you had changed the pull cord or made any other improvements to your chainsaw?

When starting one cold for the first time, I have to start these on the ground for they are not exactly saws for the little lady if not the easy start version.

I have had it a little over a year and has started ok nothing like this, I can't pull the chord far enough out to get it started.  No changes to the original machine.

Like I said when you take the starter off it is free and easy to pull and I can turn the flywheel with ease.

I am not familiar with the starter on these. Are you able to pull it over at all or is it just extremely hard? sounds like something is loose or not lining up correctly causing a binding condition. Possibly the fastener holding the starter on to the cover? Is this saw new enough to have that very fun easystart system?

It was never taken off until I had this problem, I can turn the engine over just barely with it on.  I did take it off blow it all out and then stuck it back on and it was better for a few pulls and then got worse with each pull until it got to the point where I can barely pull it.  I am 6 foot 1 in and 240 pounds and it takes everything I have to pull, it will move but barely. 

Maybe right about lining up but I have nothing to compare to is my problem.

We've been through this story before around here. Search around a little and see what you come up with.

Seems like it got down to a problem with the rope pulley itself?

Instead of using the search function, just look in the Stihl forum and look for hard to start or starter?
