I say to go with a Lifan engine. They aren't like brigg's with the shifting. On these you can go with a 70cc, 90cc, 100cc or 110cc. They are more reliable and can be reaplaced with Honda parts straight over because this is basically a Honda "replica" I guess you would call it but instead of done with imperfections like all engines that come off the line from being made by machines, these have no flaws or nothing. Lifan is an ISO 9001 certified company that manufactures over one million units per year. ISO 9001 means that all of the engines are made under strict quality control, monitored and certified by the International Standards Organization. This is a big deal, because many of the parts of an internal combustion engine cannot be evaluated by eye. The tolerances and metallurgy are of utmost importance and must be consistent with all manufacturing thus needing an ISO 9001 certification. Logistics are always a concern when dealing with an overseas product. Lifan engines still shift in the classic pattern three or four down while Honda's now shift up. The only change that Lifan has implemented is the CDI or capacitive discharge ignition, eliminating points and condensers. But other than that, I would go with one of those. To power this to the rear end, I say go with a chain drive of some sort, just fabricate one of your own. Well I don't know what else to say so good luck.
FMX, I kinda agree but, I mostly disagree. The Briggs 5 HP with the pulsajet carb is very versetile, they are used in everything from the common generator to a racing go kart. Bore them out .30 over, shave the head, port the valves and put a comp cam in it and you could make over 10 HP, this setup is used on racing carts. Yes Lifan is a good engine company but, you have to figure that they are 2 strokes so, they have more power for the displacement but, no torque, on a heavyer vehicle such as the one Eboy wishes to construct, torque is needed to get it rolling. Also 5 hp Briggs are easy to find, and have you ever checked the price tag on a Lifan? Also being he wants to build a mini Hotrod, the whine of a 2 stroke would'nt sound right on a mini hotrod cause it would resemble the sound of a ricer, now you put a header on a 5 HP Briggs, it'll more so resemble an American V8 cause of the sheer rumble.
