1986 Razz: seems to be a fuel problem but has me stumped. has tons of flow from the tank b-4 the flutter valve. seems to have enough flow after the flutter valve that should keep the float bowl full. Carb and all passages are clean I've been through several times trying to fix problem. Motor runs ver strong when it has fuel.
Problem is: it starts fine, ideas fine, takes off fine but then seems to run out of fuel if i back off the throttle a bit it catches up and starts to pull again until the same "No fuel" problem starts all over again. I'm out of ideas and am stumped, I don't get stumped by motors to often so this has become a personal challenge to get it going again.
any help would be great.
