Ok, I just pulled my 1976 Kawasaki KE125 out from sitting for 8 years - cleaned carb, gas tank, pet ****, gas line, spark plug, plug wire cap, crank case oil, and exhaust - put new gas and injector oil (injector works) and it ran like it was brand new this morning around the block a couple of times. I let it sit for 10 minutes and now it won't even act like it wants to start. I have a spark (from what I can tell - I can only see it with the plug wire cap off) but it doesn't seem like it is getting fire? Any tips on what to do next?
