Engine Accelerating
Posted: Sat Oct 24, 2020 6:30 pm
I just recently purchased a 710K. When driving it home it was sputtering and backfiring anytime I went up a hill. I upgraded to SSI and replaced the plugs, hoping this would resolve the problem. The plugs had black soot, so I am assuming this is a carburetor issue. Since I'm not familiar with working on carburetors I decided to wait and see if the problem came back. Today, it came back and was much worse than before. I could barely make it up a slight incline unless I was in second gear. Anything else and it was lose it.
The real concern was the engine started to race out of control. It was as if I was giving it full throttle. My wife about jumped out of the Pinz. I pulled over and cut the engine. Every time I started it, the engine would race. I discovered if I gave the gas pedal some back-pressure it would ease up. At times, it was fine and then kick in again. Granted I haven't looked at anything yet, but thought I would throw this out there to see if anyone else has had a similar experience. It could be a couple of problems such as carburetor, linkage, etc.
I know the first thing to do is work on the carburetor, timing etc. For the timing, I assume I need a 24 volt timing light, yes? I have a 12 volt, so could I just connect it to a 12 volt supply and use that? I'm mechanically inclined, but should I take this to someone familiar with working on carburetors or do you think I could do it myself, with the right tools and help from this forum.
