Here is a little low quality clip of my third tank of my Clockwork Racing modded Ofna JL .21 Please don't make fun of the video it was shot by my niece with a $30 DXG camera. Temps outside were 45*f, engine started right up, no shitting and did not shut off once during my running of the engine. Engine temp was around 190* I didn't beat on it much, the piston and sleeve was hand fitted for me so it doesn't need practically any break in. Engine was tested with Dynamite 086 pipe, O'donnell 97T, and Byrons Gen 2 Pro. So far this engine from Clockwork Racing feels incredible. Thanks Neal!!
