Stihl MS291 Hard to pull Starter Cord

[Will12]

Hi, So I bought a Stihl MS291 about a year ago and it has been sat in my workshop and hasn't been used. I went to go and start it today and I noticed that the cord is very difficult to pull even, so far I have tried a couple of things.

 

-Refresh Fuel and tried to start it

-Taken spark plug out, but when I do this the starter cord pulls fine as it should. 

 

Any Help will be greatly appreciated.

Oil build up on the bore has gone thick and is causing the compression to dramatically rise. Take the plug out, spray some WD40/GT85 down the hole, pull the saw over a few times and then replace the plug and start.

If this doesn't work - buy a MS181

Tried this and no luck, did take off the starter housing a couple of days ago to practise re-tensioning the spring.

Is the ignition coil catching the flywheel, like a brake pad ? Was it hard to pull before you experimented with the spring ?

If the saw turns over freely with the plug out but not with it in, the only difference has to be the compression. Try removing the spark plug, tip the saw upside down and pull over hard, this will clear the bottom end of any residual fuel.

Put the plug in and then pull the starter slowly and see if the saw will actually turn over with the plug in albeit slowly.

If it does and I suspect it will, just drop start the bugger and have done with it, it can't be as bad as a 298XP I had once or one of my vintage McCullochs!
