Stihl MS181, Hard to pull cord,wont start.

I have had a similar issue with a bg86, it had the easy start starter system. Unfortunately I never found out what the real issue was as I couldn't find a problem with anything and then it just started to turn over as normal! 

 

I would check the starter system because if it is the easy start type it could be binding somewhere when it has some resistance ie when the plug is in. I think that was something to do with the bg86 I mentioned but like I say I couldn't find a faulty component so I cleaned and greased it. If that is ok then I doubt there can be any oil/hydraulic issues now after what you have done ie plug out, saw upside down and lots of punting, so if the plug is the correct one I would be inclined to put it back together and give it a bit of welly.

My bg86 started getting hard to turn over and then just stopped! It was the top spring in the recoil the bottom spring was ok

The oil was added three weeks ago after that i just left it but now i really need the saw for the logs.

 

Ok. So, what was the reasoning with putting oil in there in the first place?

I can see the logic in that. Should be the simple start mech but even so could be something that binds when it's under load  and doesn't when the plug is out (no load).

Aye I was going to chime in with some ideas but the lad will be a while doing all the random tests that have been suggested already!

On the up side there's learning to be done. An appreciation of how a saw works and is put together is no bad thing. Might even help with using the saw once its fixed.

Yep I learnt how to do lots myself cos I was sick of being told saws were beyond economical repair, or paying for 2 hrs labour at 45 an hour then finding the saw wasn't fixed etc...
