william rushing

highly recomend. i recomend very little graphite. and for a wick i am usinf a shoe string seems to last longer. takes 3 mints to warm up off you go runs for about 20 mints i found the adjustment of the wick plays a big part in runing.
i did have to move cam timing so it would run no big deal move it little at a time till you get it to run. YouTube video placeholder
coul be be better

takes a lot of heat to get it moving and cant run it slow its ok
