well Stihl seems to have done it again , finding yet another way to screw us! Went to order a simple carb kit Gnd-107 zama for a 201 with m tronic and was told it’s no longer available, you can buy the metering gasket but no metering diaphragm? Wtf !!! The fuel pump side is universal run of the mill zama common stuff. But the metering side components are specific to that carb to allow the intele carb function properly I messed around with zama kits I had laying around but the nipple on the metering diaphragm is noticeably longer thus causing a rich running condition , unless the metering leaver is adjusted accordingly which is a guessing game! Had the carb out to replace the solenoid valve this saw has over 400 hrs and diaphragms are looking a bit flexed if you catch my drift. Yet Stihl has found a way to $&@$ is once again! Buy a new carb instead if freshening up, unreal! eBay has them listed for ten something bucks then you look an see the 16 dollar shipping charge beings they are coming out of the uk. This is getting ridiculous. Anyone come across this problem yet and most importantly of all , found a solution??
