reed valves, you hardly see that anymore nowadays.

Oiling piston out? It can only be removed if the adjustment screw is turned out completely. If you reassemble the case make sure the gasket is in the correct position (not turn it 180 degrees) and use a new gasket if the old one is worn. No need to use a liquid gasket.

Solved it- I 've put the cylinder clamshell-gasket on backwards :rare2:. Runs like a champ now! :happy:

55-60 cc

Never mind, it draws false air again after I replaced the seals/bearings:mad: (headache saw)

I rebuilt a 2008 Husky 338xpt but I can't seem to get it run right. It runs too rich and if I turn in the H-adjuster the limiter kicks in at 8-9 K rpm. According to the specs it should run at 13800 RpM. New carb repair kit has been installed, new spark plug.

compression?

A spark plug coming loose several times could indicate that the cylinder thread is worn. A loose plug causes bad compression and false air.

Brake handle is in an odd position, maybe a faller or a broken spring.

Vacuum test and not bothered to pull the muffler down? Suspicious..

One ear high frequency constant pitch, other a lower on-of ringing, probably caused by motorcyle driving. Try to ignore it as much as possible. After half a day of chainsaw use I experience sound- sensitivity for a couple of days. I wear earplugs and - muffs.

yeah, why consider it if mineral oil eventually gets in the ground water?

Durable and powerful though a bit outdated design.

I have a 630 with a bad two pcs. ignition. Flywheel and ignition for the one piece type have different PN's. I'm looking for aftermarket parts to repair it, so can I replace it with a one piece ignition and use the one-piece type flywheel? Or can the flywheel stay on? thx

it's a farmer saw, so the current Husqvarna 460 Rancher would match. <edit> mislooked on the displacement , 66 cc.

It will work fine with a windowed piston, a closed port cylinder however will not work optimal with a non-windowed piston. http://www.arboristsite.com/community/threads/windowed-piston-versus-non-windowed.75769/

Chainsaw itself; dangerous, powerful, mechanics, lots of variables which make error searching fun. Felling a tree; finally get to use your repaired chainsaw!

Only the spark-plug may sound disappointing but over time you will encounter new challenges ;)

It has autotune .:havingarest:

3/8 or 0.325"? If you bury it in wood it won't have much power left with 20" IMO
