possible carburetor problem

Fri Jul 05, 2013 8:15 pm

well i was hoping to hear the cub fire up today after new coil, new points, new plug wires, new cap, and new condenser. i just wasn't so fortunate. the tractor has a blue spark on every cylinder, has compression (felt it with thumb with plugs out) i feel air being sucked in through the air cleaner. it has fuel i pulled the main jet out and clean looking fuel flowed out and the jet wasn't clogged. the plugs are dry as a bone. with how much i cranked the engine over i would have thought it would be flooded but no gas sent. i guess i am getting at is it likely my carb is gummed up beyond the main jet or just entirley in need of a rebuild. it seems to me it has all the ingredients to start minus the fuel getting to the plugs. i truely appreciate all the help i get off this site. thanks again

spray some carb cleaner in the carb while cranking and see if it fires, if it does you have carb problems most likely

If it was running before the tune up, I would check the plug wire order and timing.
