meant to say flywheel cover or shroud, i just called it flywheel, i always make little mistakes, lol. anyways i’ve had this engine for a long time, never had a carburetor for it, so it’s been sitting in my garage for several years, until last summer i tore it down to take a look at the cylinder wall and rod bearing / crank journal to see what all it needed. I do not know what model it is, i only know that it starts with 13 in the model number, the flywheel cover is off a another engine. i think it’s a 3.5 horse, it came off a mini bike. this will be made into a stroker with my other crankshaft, that i have in the video.
