Motor misses and pops at any speed. Carb and fuel have been eliminated. New plugs. Not sure how to troubleshoot ignition problems.

Getting a guage asap. I don't remember a ball. Hummmmmm. I'll pull it apart and look see. Thanks80 is way to low get a different gauge. Did you look at the spring and ball under the primer? What do you have the low speed set to?
Under the primer assembly is a brass screw in that, is a spring loaded ball that acts as a check valve. Be careful taking it out as parts like to fly. It is not uncommon for that ball to get stuck in the spring and not seal. I am curious how you rebuilt the carb as the new kits would have had a replacement spring for that in it.
This has been a long project and I don't remember much about the rebuild. I'm pretty it had a new spring but I'll need to check it tomorrow. THanks.

The valves you are talking about are behind the carb and are called reed valves. Did you put the correct gasket on behind the carb. The kits usually come with more than one and it is critical you used the right one. That fuel pump gets it's pulse through the carb body from the crankcase if you used the wrong gasket or put it on wrong it will cause problems. When you have the carb off you can look through the hole and see the valves to make sure none are broken.
