Hello all, I have an 1986 25xd that I’m having trouble starting. Bought it for $100 as it was seized. Long story short I got everything free, disassembled the whole engine. Replaced all bearings and seals as well as replaced cdi box and wires. I have about 115lbs on both cylinders, awesome spark, and believe I’m getting fuel. I get some pops and sputters but not enough to get it going. The fuel I have is good and mixed properly and I’ve set timing properly. Is there anything I might be missing? Any ideas help!
