Help. My landlord 3410 with a 10 hp briggs 243431 is running very rough. I just replaced the carb and adjusted the fuel mix, idle, etc as prescribed in the manual. Next thing for me to check is the points. Does anyone know the gap? If that fails I will look at the coil (has battery coil which isn't original I think)and condensor. After that does anyone have suggestions? Thanks. Nick

might try a new/different spark plug. When mine gits dirty in the B112 it runs real ragged..MPH

If it is running it probably won't be the condenser. BTW, I never change a condenser if it isn't bad. I have found bad ones from the factory and problem solving that is a pain. Check the fuel adjustments and tighten the maifold bolts.

I'm in agreement with John. I've had engines run but ragged with bad condensers. You might just substitute a condenser and try it then substitute a known good coil (from a friends car/truck). IF the coil makes a difference get a replacement with the internal ballast resistor. Here's an impromptu check list: Sparkplug, cleaned and gapped to specs Points cleaned and gapped to specs Coil checked by substitution Condenser checked by substitution Wiring from coil to ignition switch clean and tight Wiring from ignition switch to battery clean and tight Check wiring with a jumper from the battery to the coil (+) check wiring with a jumper from the coil (-) to the points Start the engine and let it warm up. (at least 5 minutes) Check the HI and the LOW idle settings. Hey, let us know what you find Nick. Steve
