My question is, how did the first generation of Savages get by with a 155 main jet? Did they have the same carbon and fouling problems?
I'm not sure...I don't know what the inner working of the exhaust might have been like. Has anyone measured one? I've got the numbers for a '00.
BUT (and I feel this is a very big point)...if you look at the specs for the '86 - '88 carb, EVERYTHING was different. From the LARGER throttle valve to BOTH of the pilot air jets. Even the jet needle had a different taper. It might have said BS40 on the outside, but the insides were really different.
So, with that in mind, why would anyone think that changing one jet on a later model would make them equal?
For a comparison, there is a jetting list in the Tech section. I put it there a couple years ago.
