24 HP Intek Twin Backfiring through Carb
Please help!! I tried a bunch of troubleshooting things but still can't find the problem. When throttle is advanced, the engine 'bogs down' and backfires. So far I am stumped.
I have a new carb, new fuel lines, valves are good, new fuel. Taking the spark plugs off one side at a time has no effect, leading me to think the problem is common to both cylinders. My thought was that it could be a sheered flywheel key...nope. Next I tested the diodes. I tested both lines that lead to the armatures and they both are at 5.91V. Don't know if this is acceptable for determining if the diodes are good or need to be replaced. Any suggestions?
