    Here is my Gasoline revo
    $30 coating + extra $20 = $50. Wouldn't it make sense to run gasoline at $3.00 a gallon vs. nitro fuel at $40-$50 a gal?

    Why convert back to Nitro?

    Theoretically, but I'm not positive the ceramic coating will even work. I have already blown an ez start, ez start motor, ez start battery, a pull start, and engine back plate because it takes a lot more turning over to start and the high compression doesn't help either. The reason it takes so long to start is the carb is too big so it takes a lot to get the fuel flowing even with priming and the choke. Also with the carb that's too big it doesn't like sudden large throttle changes. So over the quarter gallon of gasoline it has had through it I have payed way more in replacement parts than I would have payed just for a gallon of nitro.

    Finally I have dreamed of this rc car sense 1st grade. I now have one and it sits around not being used because I don't have the time to finish the trial and error process to try and make it run well. I finally got to go bash RC cars with my uncle a week ago and I forgot how much I missed it. I probably hadn't bashed an RC car in 3 months when I finally did it last week. It basically comes down to I would rather pay $50 per gallon and use my car than watch it sit and never get used.

    I should have more time this summer so I may revisit the conversion then. I really want to run gasoline but I just don't currently have the time.

    That's the best answer! It's not about proving right or wrong, but to have fun. And to be able to enjoy that time with family and friends makes it that much more special.

    I got some pics of the porting. I tried to reflect all my porting with the port jobs that RB mods does and with everything else I have read on porting these engines. I know its not near perfect but I noticed a large jump in power all round but primarily in the top end.

    Crankshaft- I tried to keep the CG of the crankshaft as close to the same as possible so it isn't too off balance. I also bored out the hole a bit that travels from the carb to the crankshaft. Finally with my Dremel I delayed the closing of the intake by a degree or two to increase top end in sacrifice of some bottom end power.

    Other parts- top is the carb I crammed on my revo. bottom is a stock cylinder head vs my modified cylinder head.
