Why do my MS200's only last a 18 months!

[Steve Bullman]

my saws in the shop at the moment with carb issues and i had a very interesting chat with the mechanic. its the S61D carbs with the issue but stihl have produced a remedy for the problem. they need a pump piston kit fitted, part number 11291209701, this well rectify any probs and only costs 7.31+vat for the part.....some places might try and fit a new carb instead at the cost of around £60 plus labour

Should I be fitting the pump piston kit to my running MS200's if they have the S61D carb? How can I check if they have the S61D carb?

[Steve Bullman]

i guess theyre will be something on it that says, not sure. wouldnt bother repairing it if it aint broke!

[benedmonds]

The latest saw to go did have the s61D carb, the one before I couldn't find any numbers. My thoughts are a mix problem we generally mix 20 litres of fuel up at a time. We do shake it up but I guess that could be the problem..? Any one had similar issues?

[Steve Bullman]

its probably just that faulty carb then!

i had problems with the carb on ms200, alot of people i spoke to just put the carbs on of a 020.....

I'm going on 5 yrs with just replacing filters, fuel lines and gaskets.

 

A couple of chain brake covers they keep getting crashed.

how offten are you giving them a once over?

I just bought another MS200T because my older(little over a year old) is running poorly. What problems are you finding with yours? Mine doesn't want to stay running unless you keep gunning it. I had the carb rebuilt, fuel filters and fuel lines changed and the engine boot replaced. It still does the same thing. I used to get this problem with my old 020 but I would run it full bore on some logs for a tank or two and it worked itself out. Now that trick doesn't seem to work.

my last top handle developed a carb problem, how do find out what type of carb it has?

 

also if there is a bit too much oil in the mix what problems will this cause long turn?
