I'm trying to start this it hasent ran in years. It has good compression in both holes. The electric start needs to be rebuilt. So I'm trying to start it with the pull rope. It does start and runs for about 4-6 seconds. Here is the problems I'm having when I pump the primer bulb gas comes out the carb. No biggie the needle is stuck open. But the main thing as to why I'm confused is the top cyd. Is not getting any gas. The plug is bone dry. It's is only running on the bottom. So why am I getting no gas to the top cyd?
