357xp lives

[bluemerlin]

Was donated a dead and in pieces 357xp. Stripped it down and things weren't good.

 

 

 

Complete stripdown and rebuild. replaced piston and cylinder.

 

Moment of truth today and brrmm brmmm. Well chuffed.

Was the cylinder scored or just a lot of aluminium transfer?

The pistons seem soft on the 357's and normally don't tend to ruin the cylinder. They can normally be cleaned up quite well and reused and just a new piston/rings fitted.

What caused the problem or was it straight gassed?

Well done bud . Did you fix what caused the saw to nip up in the first place ? Maybe an air leak somewhere perhaps . Don't want it going again !

All the pipe work needed replacing. The little pipe on the inlet manifold was perforated. Carb settings were pretty lean.

 

Cylinder was very scored pictures don't really show it.

 

It's my first saw but an engine is an engine. Chain and sprocket have been hammered so treating it to new. Guidebar is in good condition.

The little short piece that curves around and almost doubles back on itself? That's the impulse pipe. Just make sure its good when replaced. Slightly to long or to short they have a habit of kinking on the bend restricting flow.

Yeah that will cause it to run lean.

Good job sorted.

 

Oh and make sure you check chain sizeto be safe when you order as they can either be .325 or 3/8

Thanks for the advice. That's the one.

 

I checked the guidebar and cross referenced on Oregons website.

 

I've done the lantra training for CS30, and lantra training for CS31 in a couple of weeks. Not sure if I'll do the assessment at the moment.

Forgot to say, Tesgol/Sawbits/Mike, top service, top guy.

I've had chance to use the saw in anger now, it's not quite right.

 

Doing a little bit of research shows that Husky replaced the plastic clamp on the inlet with at metal one. I think I'll perform the same change and see if it improves things.

Which kit did you get off Mike? The 357 big bore has clearance issues if you don't use a gasket!

They where updated due to some airleaks. You can modify the original and use a steel jubilee clip/hose clamp. If memory serves me correct the stihl 044/ms440 clamp fits ideal

With the saw running just give it a small squirt of wd40 around the inlet manifold and listen for any note change in the saw which would obviously dictate an airleak.

Which decompression system is fitted to your saw? If its the early "piped type" rather than the more modern decomp theres probably more chance of that leaking than the inlet manifold. Just blank off the pipe off at the front of the cylinder and fit the modern decomp valve.
