||Jim, Took the carburetor off my 9n, took apart and cleaned. Found no dirt or plugged jets. Re-assembled and installed. Adjusted float. Needle valve is free. Still no gas getting to the plugs. Can't figure out what is going on. Gas is getting to the carb and lots of suction at the air intake. Makes no sense to me. Any more suggestions?

||Hi Roger, I went back and re-read your first post. I forgot that you said it will start and run good if you pour gas into the cylinders. That would eliminate carburetor problems I would think. I do have two more suggestions. Weak spark or low compression. Even though you feel good suction at the carb. intake I wonder what the actual compression is. As for weak spark, if you have an old spark plug, open the gap to about 1/4 of an inch and hold it against the head with a plug wire attached of course. When you crank the engine you should see a good strong blue spark jump that gap.
