I have a Case/David Brown 1690 that was handed down to us 3 years ago by my father in law. I use it mainly to maintain our 3/4 mile long gravel drive that us and 4 neighbors live on. All the rain we had over the last week caused a large area to wash out and I had a little time just before dark. I went out hit the starter and it fired right off, but then the rpms went wild. It shot up to about 2500 rpms and I had no control with the throttle. I pulled the kill switch and nothing. It would not die. The rpms slowly came down but I still could not kill it. At that point I dropped the bucket and put it in 3rd gear and stalled it out while pulling the kill switch. Checked all of the throttle linage and that appeared to be ok. Restarted it and it did not run away so bad this time. I headed down our lane running about 1100 rpms. I could not adjust it either way. I got one bucket of gravel and when I put the clutch in to dump it the rpms went wild again up to almost 3000. I killed it the same way as before. This time it would not restart. No puff of smoke or anything. The engine turns over just fine but acts like it is getting no fuel. I have never experienced anything like this. Do I have a pump problem or is it something much worse? Thank you for any help.
