alright just installed a new pullstart on my engine it was broken when i bought the truck, I installed a new glow plug and put some fresh fuel in it. I'm not sure what the needles are supposed to be set at i set the top needle to 2 turns out and I havent messed with the lower one, it is a megatech M-16 engine. I primed the engine and charged up the glow starter. why wont it start, any ideas guys??
