I have a 1975 Kawasaki G3SS that will not start. It gets a good spark and has a new plug, I have cleaned the carb, and cleaned out the air filter. When I spray starter fluid directly into the air intake I can sometimes get the bike to start for 5-10 seconds. This morning it even ran for nearly a minute after spraying some fluid in the intake. However, I can't keep it running and it will never start without fluid.
I have used some fine grit sand paper on the points to try and make sure they are cleaned up and the timing looks pretty good to me. In order to really get in there and check the points/adjust the timing I need would need a special tool to pull the flywheel. If the timing is off would the bike start with the starter fluid? At this point is there anything else that it could be besides the timing?
EDIT: Would piston rings being worn down explain this? Not creating enough of a seal to draw up gas, but still creating enough compression to fire with starter fluid?
