Today , I fire up my buggy, it took several pulls as the owb is starting to slip a bit time to time when starting it cold.
It fired up and was running backwards!
Keep in mind, this is a Pull Start engine, hobao hyper mach .28.
I'm well aware that a 2 stroke engine of any fuel source can run backwards (as well as a 4 stroke deisel) and sound fairly normal if many conditions are right. As is the case with gasoline golf carts, (2 stroke engine) when you flip the reverse switch, you actually cause the starter to start in the opposite direction and the engine runs backwards.
But, how in the world could my RC engine have started backwards with a pull start?
Could it be that possibly with a VERY strange coincidence, that the last pull, I had almost reached a full compression stroke and it fired (slightly before TDC, as it shoud) and then pushed the crank assembly backwards just as I let tension off of the p/start and actually went through the next power stroke in the reverse direction?
That's the only explanation that I can come up with. A really odd coincidence of timing
It was a hell of a thing to see my buggy backing up at a high idle,,:OMG:
