[QUOTE="Greatdaen, post: 110648, member: 277"] My 763F was running fine. I pulled to idle and stepped off for a minute and when I returned it had quit. I fooled around trying to restart without success. Eventually, I found that if I squeezed the priming bulb it would "squish" for five or six times and then get firm. After that the tractor would start and I could run it for 30 to 60 seconds. Rinse and repeat a few times and I got it back over to the shop. There are no codes set. I did notice a small amount of fuel weeping out from the pivot arm where the throttle rod attaches to the injector pump. That is something new. I replaced the tank pickup a few years ago. For this tractor, that means in the last 50 hours. I read another post with similar symptoms and the prognosis suggested the pump was bad. I assume that means the injector pump. Is there another? The service manual shows shims for timing, etc. Is that something the average mechanic wants to mess with? Or would a replacement pump use the same shim stack? Is the pump something that can be easily rebuilt with a kit or is it something that gets exchanged for a rebuild? Any suggestions are appreciated. Thanks, DC [/QUOTE]
