Fuel problem - I think?
Posted: Sat Nov 10, 2012 6:00 pm
I've been working on one of my Cubs and have got a problem. The Cub starts fine and runs well at idle. Throttle up and it starts to die, pull out the choke 1/2 to 3/4 and it smooths out nicely and the RPMs increase. This happens with the air intake attached or removed from the carb.
Here is the list:
Replaced points, plugs, condenser
Installed new plug wires
Timed with timing light
Removed play in the governor linkage
Fuel tank is lined and clean
Sediment bowl is clean
No fuel filter in the line
Filter screen is clear in the carb
Rebuilt the carb
Excellent fuel flow when the plug is removed from the bottom of the carb
Excellent fuel flow out the hole holding the metering jet
Metering jet cleaned with copper wire and blown out
I believe my problem is fuel related. What am I missing?
Thanks for your help.
