FYI - Whilst over at Probuild for some gear and fuel, Andy introduced me to these GP Engines from Taiwan which have had great reviews in the US. One he suggested I might like is the GP61. Looks a bit better than DLE but not as polished as the DA the latter lot's more money. I like the fact that they have recessed the carb a bit more into the crankcase reducing the need for long standoffs.
Specs are :
The GP 61 is a powerhouse of an engine. We are trying to develop the best Gas engine on the market.
