Pull-cord kickback when starting a STIHL MS 660

[njm]

I am still experiencing having the pull cord handle ripped out of my hands with the same old 660. It happens consistently when milling, restarting the saw while hot (within 5 minutes of having milled).

 

It kicks back like a motherf..... – really hurts.

 

Even when pressing in the decompression valve (which pops back out when it kicks back). The best way to start it is to gently pull the cord, without pressing the decomp valve, until you feel compression, and then give the pull cord a short sharp pull with BOTH hands, while the saw is on the ground held down with my knee (saw mounted on the Alaskan mill). But even with this technique, it still pulls the handle out of my hand every other time. I really don't like this situation. Time for a new saw, maybe (STIHL 880, Husky 3120)?

 

Any new advice fixing this problem once and for all, beyond the advice already mentioned by Garden Kit, adjusting the ignition gap?

 

Sounds like the saw could be flooding , i never find the need to use the decomp on a 660 when it is hot . weak lever spring or worn needle would cause the saw to flood after a hot shut down ..

Nah, we have you as a 6'4" 25 stone guy dressed in cow hides and a helmet with horns on it and a penchant for boats which are long and have lots of oars:lol:

 

 

 

Good luck with the timing as it is the most likely fix. If it is a real issue, you could take the flywheel off and retard the ignition with a customised flywheel key!

 

 

 

It is possible that the decomp valve is a bit weak and pops out too soon before the engine has truly fired but think these issues have been mentioned before.

You can get pills or cream for that:lol: Yeah, not far off:thumbup:

So I have a Husky 181 that is a bit like this (and there's no way to retard the ignition - that I ever found) and one day I found the best bit of advice I think the interweb ever produced (well in relation to chainsaws anyway)

 

" start it like yer stole it"

 

However one thing that I do do with this saw is pull it over with the ignition off for the first two "on choke" pulls, then move the ignition to start and usually there's no kickback and associated cussing!
