Its been sitting in somebody's yard for years so have no idea how much work is needed to get it running and Im learning as I go. I've compression tested both cylinders and getting 128,129. Replaced all the fuel lines, rebuilt the carbs. The starter seems to have plenty of power..I checked the reed valves and they are fine. I'm getting a spark on both new plugs. I've squirted a bit of fuel down each cylinder but it just doesn't want to ignite at all and just turns over. So its got spark and fuel so I can only guess its not getting oxygen to ignite but I have no idea what to look at next! I haven't took the head off and inspected the cylinders but if there is compression I figure it should be OK? Any pointers would be greatly appreciated!
