Thanks for the input, guys. I have read about the shortcomings you mentioned, both the connecting rod and additional engine temperatures. It seems some have reported good results while others have experienced less than favorable results. One thing that seems abundantly clear: If it were as simple as converting from glow to gas, O.S. would have already done that instead of going through the growing pains they are right now trying to engineer and produce a viable gas engine. Again, on reports via the web; since the guys testing these various conversions are not in a controlled environment where gas to oil ratios, air temperatures and other factors can be kept consistent, there is no way of knowing who or what to believe exactly. Unless the oil viscosity or oil mix ratios were out of spec, not really sure why a bushed connecting rod should be a big factor. After all, that's exactly (almost) what's in any automobile engine and certainly not needle bearings, so it's not clear to me why needle bearings would be a must. In the long run, it would probably be more reasonable to buy a known, reliable gas engine rather than convert. I guess it's the 'tinkerer' in me that makes think about things like this more than it is being 'reasonable'.
