My son just picked up a 224. The carb needs some tuning but first we need to get some decent fuel run through it. The seller said he cleaned the carb but the fuel is a few years old. I’m not sure if he hooked up the throttle spring in the correct holes. There are a lot of holes in both the throttle side and the governor side. He had it in one of the lower holes on the governor side. The spring didn’t seem to be stretching at all. We moved it up a few holes and that seemed to help a little. Where’s it supposed to be?
