My ten year old MS200T starts, idles, accelerates and revs to 14,000 rpm, but bogs down in a heavy cut. I've been using the saw almost daily recently and it seemed to happen overnight. When I noticed it I cleaned the air filter and put on a fresh chain, that didn't help. I read here about problems with accelerator pumps, so I pulled the carb off and I don't have one, it's a Zama S61A. I went through the carb anyway and everything looked OK. I don't run ethanol diluted gas and have always used high quality synthetic oil. I removed the spark screen when I got the saw but I pulled the baffle out and ran it that way, it did get more responsive but still bogs down in a heavy cut.
No one but me has ever run this saw, it doesn't have a ton of hours on it but it does get used hard periodically. It's always impressed me until now, it will cut limbs fine but doesn't have the torque to cut 12" soft wood logs like it used to.
Does anyone have any specific advice for me before I tear into it?
