[B]This is my thoughts. You say it has spark and it is a fresh engine done by BW, so we assume the compression is good (hard to do a compression test on a engine with the decompression mech.) and you say you are getting fuel. That leaves two possible problems, Timming (ignition or valve) or to much fuel. you say the plug is wet when removed? I would remove the plug and diconnect the fuel pump and crank the engine over to get all the fuel out of the cylinder. Then replace the plug and try starting it without connecting the fuel pump. if it fires or not then hook up the pump. If that dosen't work I would then pull the flywheel and check the Keyway on the flywheel.
The saga continues.... I disconnected the fuel pump, pulled the plug, cranked and cleared the cylinder, put in a new plug and nothing. I spoke to Cord over at B/W and he suggested using starting fluid down the air box just in case the rings were stuck and it needed a little boost for it's first start....no luck but I got a small fire up the airhorn from the backfire. In fact I have a pretty consistent backfire with the throttle open. So I guess I will have to track down a flywheel puller and check that out next. Stay tuned...........
