OK good. Be sure to try without priming in any way. Some carbs have built-in filters if that is what you mean. If there is an inline separate filter, do not test thru that filter. Are you still using the gas can, not the gas tank? Hope so. Tomorrow it is. The flow should be a near full hose full, not a trickle, not weak. It will pulse as you crank. If battery is low, it will affect the flow some and it will take longer to begin flowing. Be sure you are using genuine fuel hose in the gas can or it will collapse and you won't know it. If you see a good flow, hook it back up to carb WITHOUT any inline filter and start motor. If carb has a filter inside the inlet port, replace it. See how it runs. Be sure gas can level stays up. After motor warms up a little, it should not need any choke at all but if it needs some choke to run, see if it will run and idle and rev that way. It should only take zero to three pedal pumps before cranking to start depending if cold or warm. Some carbs need one quick pump to set. We will get Carbking to advise once you see a good flow to carb. Give the carb numbers and what it says, like "2 Jet" or ?
I assume this motor ran well after carb rebuild and before storage....."a few years back". That is a nice motor.
