    ive had my 66cc kit for about 3 months and i want to try something that isn't just from a kit. it seems the best price to performance engines in my area are in lawnmowers or generators (whipper snippers have best price to performance but to small :p). the issue with a lawnmower is the vertical to horizontal conversion which i'm happy to try but if a generator motor is suitable i'll just use that. also can you do anything to these engine to reduce the fuel consumption so that they don't guzzle insane amounts of fuel? like adjusting carby. im mainly going for a bigger CC so that it doesnt have that high pitched whine we've all come to know xD.

    Hi PA, welcome!

    I been thinking about using the very easy, cheap and would look cool vertical shaft lawn mowers for years. Would be so cool. And 4 smoke. Now weed whacker whine.

    Many, many ways it could be done. A plate driving a wheel that could double as a gear ratio changer. A worm gear. Already mass produced for lawn equipment.

    OR, a really funky, multiple, belt slowly altering orientation.....

    There are threads here on great successes and some spectacular failures, LoL. No bout a doubt it, you can do it.

    I find if I let my mind wander when first waking up or going to sleep, I can see thees thing/ideas flow like water. Your imagination is the only limit.

    Go threw some threads using your ideas as key words. Some one will have tried it and will save you some hair pulling.

    All in all harbor freight predator engine, with coupons, less then a $100,

    Generator engine my have special shafts, and hookup, so check that out, same with water pump engines.

    Lawn mower engine, measure twice has turned one on its side, and made it work, also not seen here is a twisted belt. Cannanball2 I think has done one sorta on a Maytag build. Or as Dan said lot of old lawn mowers had right angle gear boxes on the beck, to run the blades. Also talk about using right angle grinder gear box, never seen it cone about though. LOL

    Go back and study this DIY section and you will see all kinds of different builds
