Re: Stihl MS192 or Echo 360T anygood?(first climbs
Never had coil issues, and i've run scads of 335/338's. Spark plug cover is now affixed with a screw.
My point is this, a 200T with the screen removed is about the same noise as a 338 with an added port, thus, it is effectively about the same amount of muffler restriction. Bone stock, a 200T is louder, meaning it has less restriction. Thus, the gain from removing the screen on the 200T is less than the gain from adding a port on the 338. And, why the 200T makes more power stock than the 338, and why the spec sheets are inaccurate.
Carb issues seem to be solved as well on the final iteration of the 338/2139. The only irritation is the need to choke a warm saw after its been shut off for as little as a couple minutes.
Rich Hoffman added another port to his 200T, which may or may not have made it cut faster. Fact is, the 200T has so much rpm and runs lean, that you risk lean seizure with just a muffler modded saw, which is capable of turning 16,000 rpm, or at least reduced engine life. Not an issue with the 338's which still turn at about 13,800 when ported.
Full woods porting won't accomplish anything with a clam sheel design saw like the 338, but will make a 200T scream Ed Heard did two for Craig Jabs. Great saws, but did they last? They were mighty fast, I know that..My saws are fast enough.
