One I get the taste out of my mouth, I may just take a look at the MP Jet and see if I can make the airbleed adjustable. That should allow it to idle. It does pretty well on the top end. Did MP Jet offer a twin needle carb on some of their engines? One wonders why they weren't standard. I chalk it up to yet another example of tarditude on the part of engine manufacturers.
DT, Yes, the bb RC version does have a dual needle carb, which is a very nice unit. It also has a collet prop drive. Unfortunately the carb & the bb version of the engine are nearly impossible to find, even on the auction site. I had been searching for one or both for over a year, when I finally lucked out. A friend of mine was getting out of the slimers, & gave me his .061 bb RC version. I consider it to be a real treasure. Only negative I can come up with, on this engine, is that it is heavy compared to the Norvel ........ George K.
