I have a very nicely treated, low hours XTM .15 with a slide carb, and pull start that is being neglected on my workbench? Has sat the last few months with after-run oil in it, airfilter on the carb, and a piston locker holding everything at bottom dead center. It has a ported Ofna header bolted to it and Wolfpack Radicals heatsink motor mounts attached ($35 mounts)
Engine is rated to 0.9hp @ 39k rpm, not a barn buner but it has a ton of low-mid end power, ran great at my local small'ish road course in a nitro rs4 2 with 2speed, I sold the car and the engine has sat since, maybe 1/2 gallon through it, was tuned to 210`F and was very strong and consistant.
