Just finished another Huztl MS380 build last night. She fired on the third pull and runs well after some tuning. After shutting her down, I noticed (for the first time) that there appeared to be some extra play in the piston/con rod assembly. Remembering and reading back a bit in this thread, I note I am not the only one - and perhaps the small-end (wrist pin) bearing is not quite right. It seems that there is a degree or two of flywheel rotation at the top/bottom of the piston stroke without any corresponding movement of the piston itself. Seems to be a bit more than the normal "top-dead-center" I'm used to.
The bearing looked fine when I inserted it into the upper con rod, but I will admit to not checking it against the wrist pin before installing the piston.
Wondering what y'all think. Since it ran, and ran well, is this just my imagination working up a problem that doesn't exist? Or do I have a time bomb waiting to "grenade"? Anybody else running one of these saws with the same condition?
I do realize that it is not that hard to pull the jug and look, but I thought I'd ask before I made it a project. I don't know about you, but these things never seem to go back together as tightly on re-assembly as they do when assembling for the first time. Plus, with my luck, I'll break a ring the second time .....
I built a 380 and noticed a lot of slack at top and bottom of the stroke. I took apart a found they sent the wrong wrist bearing (it was for a ms440). I replaced it. I'm sure it would not have lasted long with the wrong bearing. It was obvious when I took the jug off. Not sure how I missed it during assembly.Bump

It was a couple of degrees of slack. I could feel it by hand.Thank you. By "a lot of slack", do you mean more than a few degrees of flywheel rotation? When you spun the engine by hand, could you "feel" the freeplay?
Get it sorted out?It was a couple of degrees of slack. I could feel it by hand.

When you have a ms440 wrist pin bearing in a ms380 you can tell. I installed the correct bearing and all is good.Get it sorted out?
Doubt you can tell slack in a pin and bearing unless you have it apart
I have not built the ms360 or ms361 kits. I've built at least one of everything else. I think the ms660 kit is the best deal and the quality is good. I think the ms380 kits are the best quality and and most heavy duty.Tbohn, would you recommend the 380 kit? Pondering the 360 and 380 kits
Good you got it sorted!
I think the had a 10mm and 12mm. The 12mm fits on the ms380 wrist pin but it's OD is too small.If I remember right the 044 had two different wrist pin diameters, 8 and 10mm.
Or maybe the ID is too large...I can't remember.I think the had a 10mm and 12mm. The 12mm fits on the ms380 wrist pin but it's OD is too small.

Did you use any OEM parts to finish the 380?
