" If anyone can help I would sincerely appreciate any ideas. My problem is when I run up and get to about 40 mph the engine power is lost and falls off to idle. I can sit there a minute and engage full throttle and shoot out of the hole with full rpm and get to about 40 mph and experience another power loss, having to bring the throttle to neutral / idle to keep engine from dying. Anything under 40 mph I can run all day it seems experiencing no abnormalities. I have cleaned out fuel tank, blew out the fuel lines, replaced primer bulb and fuel line "O" rings at connections on bulkhead and motor, checked fuel filter screen (clean), checked for good fuel connections, replaced gasket / diaphragm in electric primer, filtered fuel with secondary filter (it is clean), replaced plugs, replaced fuel filter screen, fuel flter cap and associated "o" rings, and rebuilt the fuel pump. The carbs were rebuilt 2 years ago and when stored the engine has always been run until all fuel in carbs is exhausted after removing fuel line so I am pretty sure they are okay. Thanks! "
