ms 201 lack of power?

[simonm]

Just started cutting out, and with a lack of power to the point where it wont cut? starts up again and then the same thing happens? what could the problem be?

It could be fine saw dust in the carb inernal gauze filter or just a bit of resin in the carb. A good ultrasonic clean should sort it.

 

Other than this, check the plug is in good condition.

 

Worth checking the compression or taking the exhaust off to see that the piston is OK - the muffler inlet has a flange around it making replacement much easier.

 

I have had one with a split inlet manifold which had no power and would not rev out - another thing to check!

 

Good luck, let us know what you find

Thanks spud i will have a look tomorrow, i have heard that drilling a hole in the muffler will increase power a little?

Yup, it is the simplest way of getting the saw to perform something getting closer to the MS200. Just stick a 6mm drill through the part that comes through the side cover and follow it with a 10mm drill. It will make the saw come alive but will not fix an inherent fault if there is is a fault with the saw!

HI SIMONM sound one very large night mere mate send it to STEVE SPUD to get ported thanks jon

[simonm]

Oh no i understand that i need to find the fault, but i would also like to improve the performance also, so once the hole is drilled is that it? no adjustments or mods can or need to be made?

Just for safety sake, turn the H screw out 1/8th to 1/4 turn anticlockwise but that is about it - it will make a real difference!

You can improve the performance with the Stihl " enhancement kit " which has in it a new flywheel ( ignition advance a bit ) and spark unit ( I think ) and possibly a new carb ? Anyway its what the have done to the newer ones from the factory .
