9 N runs rough carb?

Anonymous-0 · Aug 17, 2008

My 9 N runs rough at idle and not much power for bushhog or finish mower. Linkage bent to make up for weak govenor spring. Starts with one third choke and throttle at one third (the way it should) but no power unless at full choke and full throttle. Gets worse when it gets hot (30 minutes)

Plugs and wires need to be replaced. Coil, cap, etc are good. six volt system. new radiator, runs a little hot, fan belt is tight. Always use fresh gas-good gas flow-everything in system is clean, no gas cap vacumn problem as far as I can tell.

Loud-could manifold gasket be letting air suck in and thereby require full choke? How to test? Replaced manifold two years ago. It"s tight.

Thanks IF anyone in eastern Pa has something new and stronger for sale, let me know.

Well first off do you have a good blue/white spark at all the plugs?? If not theres your problem. Next do you have a good steady flow of gas for 5 minutes from the drain plug at the bottom of the carb. Turn the gas off, remove the drain plug and rig up a way to catch the gas. Turn the gas on and let it flow for 5 minutes. If the flow is not like you taking a leak its got a fuel flow problem
