Quick update on the saw. Its running really well. I have been doing some milling with it. I'm running my 36in bar in a 20 inch cherry log.

I changed the bearing the piston rides on. Smoothed it right out.
Yes I put a the whole cross top end in ( ie the piston, cylinder, rings. ) with no base gasket.

I swapped out the wrist pin bearing. That appears to be the problem. The saw is alot smoother now. Thank you everyone for the suggestions. I still need to check the clutch.

Yes. No marks on either crank or piston. Also made sure to pay very close attention at bdc for any binding/hitting feel.

I'm hoping to fire it up in the next few days to see if the bearing swap fixed the problem. Then I will go from there.
The huztl saw is a base gasket delete with minor port job on it. Basically a smoothing of transitions and widening of the ports. and gasket matching the muffler with a muffler mod.
The saw ran smooth before the cross top end. I took a huztl big bore top end off to put the cross on. Because my base gasket deleted Huztl 660 would out mill the big bore saw. So figured I would try the cross top end on it to see if the 2 would cut roughly the same.

I didn't notice anything out of the ordinary on the flywheel. But I forgot take the clutch drum off and look in there. The drum spins fine.

No missing sockets. Lol. I swapped the piston bearing for a hyway one I will see if that helps. The were no hitting marks on the piston or crank. Everything felt really good. Besides the wrist pin felt really tight on the bearing. So I swapped the hyway one in. Hoping to have time tonight to...
Quick update. Piston is in the correct way. The cylinder has clearance to the case. So the cylinder is coming off.

No Stihl calender. Lol. But there is always that possibility I did put in backwards. I can pull the muffler and look for the arrow.

I will give the cylinder a look and see if it's hitting. At this point it's easier to tear it down and give it a good look over then having the saw go into total melt down.

99 percent sure the OEM one. I put it together a couple months ago.
Which this saw is roughly a 2000 and I accidentally burnt it up 2 years ago. I leaned it out to much and scored the piston. But it cut rally good there for a bit. Lol

I just finished putting a cross top end on my 660. I started it up with no bar just to get it going and noticed my hands started hurting will revving the saw with quick blips of the throttle. So I paid attention and the saw has a nasty vibration now. I started my Huztl 660 just to make sure I...
So I'm checking my huztl carb over. And with way it smokes when I first start it. I would say I have a metering level off. I'm trying to find a video on how to set it but I'm having no luck. Plus I put my mityvac on the carb and it hold pressure until about 20 psi. I believe I read that suppose...
