So, to recap, I had some alarming issues come up with the throttle last weekend on my return from a dump run. Specifically, I lost about 40% of my available power on the way home, out of the blue, with no advance warning. As it turned out, the issue was not with the carb or the engine, which I feared, but with the throttle cable itself. There’s a trio of clamps which theoretically hold the cable into place, but up until last weekend, the vendor’s sticker was the only thing keeping it from moving as the throttle advanced.
Sunday I got a little time while Finn was asleep to poke around under the hood, and I made a fix to the third clamp in order to keep it from advancing: about four winds of electrical tape under the clamp now hold it in place without binding the cable. I took it out for a test spin and everything seems to be fine again.
