troubleshooting a 385xp

[oaky]

got this old 385xp going again. found out it needs a off switch and a new tank vent/connector fitted in (leaked gas). but it did run well. 150 psi compression rating..
but
seems to be making a lot chattering noise on the flywheel side of the saw. listened at the clutch side not as noisy as the flywheel side/top end. check for loose screws/anything hitting the flywheel..nothing.
no play on the bearings either side as far as i could tell, maybe i missed something inside, maybe to much clearance on the cylinder i sanded, piston slapping? dont know.

anyone have any videos of a saw running with piston slap?
or any other ideas would be helpful as well.

Yes, troubleshooting the idle tick.
I’d never seen one that bad before.
New piston and she was right again.

@RIDE-RED 350r may be able to shed some light as well.

just a piston?

Yes, the raw aluminum piston wears much faster than the plated bore, however the bore may have some wear.

tax returns are coming so ill probably throw a new 390 kit on top.
there easier to find than a 54mm oem piston plus only 60bucks more.

A meteor piston kit with Caber rings can be had for around $40, if this is the issue with your saw, I’d slap a piston kit in it and beat it like it owes you money.

 

[huskihl]

Yep me too. Nothing wrong with a meteor. Just clip the ears off the c clips or use oem clips

https://www.hlsproparts.com/product-p/544-00-65-02.htm Like 2 bucks more than the 385 kit. No brainer. However... I’d throw in a meteor if your used cylinder is still good though like the others said. No sense wasting it.

Can alwaksee if this guy has a kit left.

[oaky]

ill pull the jug and go from there, if it looks alright still maybe ill try a meteor

alwaksee wanted 22 for shipping, hisproparts is free shipping.

Bone stock I'd take the 385 top end over the 390.

If you go with a new 390 kit I'll take that 385 cylinder off your hands.

Not likely.
