MS200t problems

[Marko_87]

Having a few problems with my 200t. When I put it on full revs it sounds like its starved of fuel, oddly it seems to run fine with a full tank but starts to happen as the tank becomes about half full. I have recently had a new carb fitted (about two months ago) which was running great when first fitted, also had it pressure tested and that was fine, fuel filter is clean. Any ideas?

 

Cheers!

Possibly a hole in the fuel line but it would be a first. The fuel filter may not be sitting down in the tank properly, sometimes they ride up and when the fuel gets on the low side, it sucks in air.

 

The carb may just need adjustment after the parts have absorbed fuel...........

 

The carb may have ingested a bit of wood chip so it is worth checking the internal gauze strainer.

probably a split in the pipe inside the tank so when the tank gets low it pulls air instead of fuel

Doesn't sound like it's worth fixing...send it to me..

I've found similar things before when the black air tap fuel tank breather thing at top of fuel tank had deteriorated

mine is doing the exact same. so would be interested if you get it sorted,

I remember something similar with one of my saws, it turned out to be the filter not sitting at the bottom of the tank properly. My favourite kind of tool fix, easy and free

Tell me I am wrong but I think I mentioned this in my earlier post:001_tt2:

Filters sitting fine so unfortunately not such a cheap/quick fix :-/

 

A couple of people have mentioned the breather, need to replace the fuel line as well now as it tore when I was removing the fuel filter. Ordered a new filter, fuel pipe and breather so will say whether or not thats solved it when I've fitted it!

TBH Marko, the pick up hose does not tear easily, unless it has degraded, so I reckon yours had degraded and its a fair bet there was already a split partway down which allowed it to suck air when the fuel level dropped.

 

I'll bet the new pipe will sort it out nicely and cheaply. Good luck.
