Hi
My JD318 1989 lawn tractor seems to have limited or sporadic control over the engine speed. It varies without me touching the rabbit/turtle. Particularly surges. When I mentioned this to the dealer when buying deck parts he said that’s not good... I would love to save it as it’s a workhorse or is it time for a new one? If so, what can you recommend as it’s been 32 years since I needed to look! Currently I have a 50” deck and would only consider smallest 48” or a lawn service 😞. Thanks in advance
Donna

Can you pull the choke out to a position where the surging goes away? If so, it's probably a clog in the carburetor or a leak in the intake manifold. Try it and let us know. We can give advice from there.
