Stuck reed valves?

[psc1947]

Stihls and Husky. After sitting for too long (cancer, broke back, knee repacement, when it rains it pours ) incredibly hard to pull. Stand on them and strain to get one bump at a time. Turn freely with plug out. Any trick to free them or prevent sticking (if that's what it is?
Thanks

Sorry to hear that. Most of these small 2 strokes don’t have reed valves. Some equipment has a compression release button or lever to make it easier to pull over. Stihl saws have a button on the top of the cylinder. I always spray some fogging oil into the carb throat when putting something away for the winter or summer. Any marine store has it in a spray can for about $5. I drain the gas fire it up and run it till it starts to die then just spray a bunch into the carb air inlet till it dies. Then I pull the plug spray a bit into the cylinder and pull it over slowly a couple times. Then I put the plug back in and it’s good to store for years without any worries about anything sticking or rusting. Works for any gas engines 2 or 4 stroke small or large. Don’t use it on a diesel it will just run away and the oil will burn off immediately.

Any hints on how to free it up? Literally have to stand on it and pull with both hands to get it to move at all, then just one stroke at a time. Spray PB Blaster in spark plug hole?

Can’t hurt to try if it’s tight without the plug in. What is the equipment in question? If it’s pulling over easy without the plug in it sounds like it might have a clogged exhaust port, muffler, or spark arrester screen.

Husky 345 ($75 garage sale spotless, looks brand new) Turns easy with plug out but i will check exhaust. I've had Stihls do the same thing and turn loose eventually.

Interesting, it almost sounds like it’s hydro locked but it shouldn’t be if you pulled it over a few times without the plug. I’d pull the muffler check for a blockage and take a good look at the piston and bore. Is it possible someone put the wrong spark plug in? I’ve seen too long a plug installed in an engine that hit the piston at TDC. I’m not familiar with this particular model but most huskies I’ve run had a decompression valve on the right side of the cylinder. If yours does push it in and try to pull it over.

Husky 345 X-Torq. No decompression that I can find. Ordered extra long hex key, muffler bolts are 5mm cap screws recessed 1-1/2" into muffler body. Spark arrester screen spotless.

One thing I learned from 30 years in industrial maintenance, "It's usually the simplest thing."

Thanks for your input.

You might take a look at the pull starter mechanism, I've seen them cause the problem you describe. The rope cuts a grove in the wheel and makes it hard to pull over! Good luck and keep us updated!

Easier now but not enough. Put piston at bottom of stroke sprayed WD40 in and left overnight
Gonna find my PB Blaster and try again.

I'll tell you, if you have any carbon on top of the piston, the PBlaster will dissolve it quickly, and it will run down into your ring(s). I tried it on trash saw I picked up and broke down. I was impressed how much it dissolved though.

Something worked! Removed muffler but no help.Used gas and 2cy oil 50/50 in plug hole. Tried it. (had to c-clamp to table) Let sit over night treated and tried some more. Finally loosened up and fired.
