I have a NAA (12V conversion) that I keep at my hunting camp (about an hour from home). I mow with it about twice a month. I usually just add the gas I'm going to use to keep from leaving in old gas. It always fires right up with a little choke evens out and is ready to go. The last two times I used it, it still fired up, but wouldn't take any throttle. Choke just made it worse. It almost seemed like the governor was pulling back against the throttle extra hard. After 3-5 minutes, it started taking throttle (although under powered at first), but seemed to be ok after a while and started running with normal power. I mowed for about an hour or two with no problem. Seems like I never have much time when I'm over there, but planning to try and diagnose the problem the next time I'm over. The Autolite 437 plugs, wires and points haven't been changed in a couple of years. Just looking for some suggestions on where to start. Due to the location, I really need to take parts with me for replacement (if any need to be replaced).
