Dual,

I tried my .15 in freezing temps a couple of weeks ago... it ran and fingerstarted fine on 0% nitro fuel... it bites when flooded though, but starts better because the bearings move more freely.

Don't forget to take the engine apart and look for burrs and tailings. The last three MVVS's I bought (except the 1.60) all had metal bits in them! My 1.44 twin had a lot of tailings in the piston pins... you don't want that stuff wandering through your engine!
