My new/old Stihl 044

[ropensaddle]

I put the old groovy jug back in. I'll consider it an experiment until Junky sends me a possibly less scored jug to try out should mine grenade or be unacceptable. I nearly have the whole thing put back together, but I'm waiting on the carb kit which I ended up deciding to install. I popped the bottom of the carb today to check the inlet screen and the rubber gasket wasn't exactly pliable. I reckoned that if that gasket wasn't pliable, then other things might not be pliable, so I'll just install the kit..

Oh, and I picked up an 046 dual port cover for the muffler as well. May as well, right?

After it's together, I plan to start the saw at about 1 turn out on the high speed screw (3/4 turn is stock), let it warm up a bit, then set the RPMs to 13,000 give or take a few hundred. Sound like a sound plan? I hope it runs.

If I could rep you guys anymore for your continuing help, I would, but apparently I've not spread the love enough...

Yes!

Ive got an 066 that has a couple of grooves just like that!!!

after honing,,,,,and they didnt go away visibly, but you couldnt hang a nail,,, the cross hatch was pretty so.... having done it before in my cart racing days with 100cc Yammy moto'

I put a fresh piston kit with new rings of course when it first went together it had 155# after about 5 tanks

It makes 160+ lb of compression on three good pulls and that saw absolutely kicks butt!!!!!!!!!!!!!!!!!!!! you would never know it had a couple of grooves in the bore,, it should have alot of life left, Im sure you will be well surprised...

Ain't this fun?????

Well, I can certainly feel the grooves with my nail, but I wouldn't say they catch. We'll see what happens. I've not put a compression tester on it, but when I held the powerhead (minus the weight of a carburetor and carburetor cover ) up by it's pull cord, it demonstrated that it had more compression now than when I tore it down...

Yes.

Yes.

Be careful testing this way after putting it all back togther... Assembly oil on the piston and bore can raise your "compression" a lot...

Good point. Even though my compression tester is of the wrong ilk, I may connect it anyway just out of curiousity after I run the saw to clear the assembly lube...

Got my carb kit in today. Tore the carb down, sprayed with carb cleaner, then sonicated the carb body in naptha for 5 minutes and it was dirty... I put everything back together, taking care to set the inlet control lever flush as per Lakesides instruction in another thread (stupid Zama-biased service manual) and put the rest of the saw back together with the high speed needle set to about 1.25 turns out. Went through the normal Starhting procedure and it lives! After letting it warm up, I tuned the high speed needle by ear and I believe it's a bit rich at 1 1/8ths turns out, so I'm pretty sure there aren't any significant air leaks anywhere. I'll tune with a tach in the next day or two to see where it really is.

Thanks for everyone's help in this thread - I'll take some "after" pictures soon and post them. I think I scraped about 1 lb of oil drenched sawdust and grime off of this thing - it feels almost as light as my 260 now.

One observation/wonderance: while putting in the wristpin, I did not need to use heat as per the service manual to get the wristpin into place - it slid smoothly into position. I used the aftermarket (Bailey's) wristpin. I couldn't feel any play in the direction of the stroke after assembly. I'm wondering if I should have used the OEM wristpin for that extra ~0.1 thou tighter fit.
