Ms 200t problems not staying running and barely idles and revs high then cuts out

[spudulike]

I have been in the saw today. The main issues that have caused the running issues: -

1) Impulse line off

2) Accelerator pump significantly worn

3) The cylinder has seized at some stage but only lightly. The transfer has pushed the piston toward the back of the bore and it has worn the plating off. I am thinking this rather than ingress of chip through the inlet port as is more common.

Other issues - The bottom of the oil tank has worn from the outside bottom where the saw has been stood on concrete and now leaks.

One of the muffler screws is M6. 

Clutch cover is pretty shot but am already waiting 2.5 months for 2 on order.

Brake band worn.

A few other bits and pieces.

As noted, it's definitely had a life 😳

Yes, a glance at the bottom of the oil tank proves that. Simple fix to the leak is to degrease the central foot bit of the oil tank and bond some thin metal to the case with JB weld which seals the oil tank and makes a stronger foot.

Much cheaper and easier than replacing the crank cases!!

Sounds like it's ready to go to 200T heaven.

Clutch covers! I think we've got 3 or 4 waiting for them to arrive. Sometime this month I believe. It's a ball ache for parts at the moment

All done and back with the customer. Annoyingly, the previous owner had put a screwdriver through the inlet manifold and that is an expensive part with aftermarket parts being pretty crap so a new OEM part fitted and a new crankshaft seal as the original was leaking.

All should be good now but always sort out any annoying issues in a reasonable way if the first pass didn't sort them and show up again with a bit of running.
