Hey, ive been reading this forum for a while and am really considering converting a gas engine and throwing it on either a 1/4 sig cub or spacewalker 2. i was wondering what size of engine i would need, and which brand is "the best" or the "OS" of conversion engines. i know this could be a classic "ford vs chevy" matter, but i dont want an engine that will give me headaches and shy away from gas conversion engines. any input would be greatly appreciated.
thx,
andrew

The vast majority of gasoline fueled engines that are used in models are conversions. The only problem with conversion engines is usually the weight, or some awkward configuration of carb or exhaust that can be bothersome, when compared to the ideal. Fortunately, most applications for such engines are not critical in this regard.
The largest single problem with all gas engines is also its blessing and major advantage - the carburetor. Most are Walbro manufactured carbs. Those that are not Walbro brand generally follow the Walbro theme. The EPA influenced carbs can be problematic. Fortunately, loosening to bolts/nuts can rid any engine of the EPA carb problem rather inexpensively.
If you are looking for a problem free engine, you are in the wrong aspect of this hobby. All engines can be problematic from time to time. All need maintenance and attention in order to function problem, just like your weed whacker, if you have one.
If you are expecting something that is strictly plug and play, do yourself a favor, stick with the simulator. Otherwise, most engine brands are similarly reliable, with the more expensive brands usually being the best. If you don't like to tinker, stick with a simulator.
