VM 340 carburetor elevation compensation for jetting. 4500' elevation, 0-30C temperature. The #260 came standard. I also have a #250 and #240. I'm interested in the Amal type jet. I'm looking for an elevation correction chart like I have for my Bing carb. Actually, My Bing Correction Chart should work. 4500' elevation, 30C-40C has a correction factor of 0.94 = 244 and 10C-15C a correction factor of 0.96 = 250. Anyone have the full part numbers for these, 244 and 250, or whatever sizes are close, in the Amal style?
