Working on a 1999 300 2×4. It wouldn’t run except on carb cleaner. The valves knocked and the starter died. I changed the starter and adjusted the valves to .006 and cleaned the carb. I pulled it apart and stuck everything in my sonic cleaner with simple green for 20 min then rinsed in warm water then used air to dry. Everything seemed to be clean.

I put it back on tonight with a armor tech cr222 carb kit from the local dealer and added 1′ of clear fuel line and a clear fuel filter. When I opened the fuel valve no fuel flowed. I took the line off the valve and was getting good flow out of the tank so that’s not the problem. I removed the filter and just made a short line straight to carb. After pushing the primer bulb about 100 times I took it off and no fuel is behind it. Is it supposed to?

It will crank and idle for about 5 seconds then die and won’t re crank for about 5 min. It runs fine if shooting carb cleaner in the intake Any ideas on what I missed.
