I don’t know what these pieces are called but I will do my best to describe them. Throttle linkage, screwed on a threaded rod I have a plastic ball socket. on the engine throttle linkage I install what looks like a micro steel ball the back has threads for a micro nut well the nut is missing so I epoxy this ball on the engine thinking there was not much stress but I did not consider the heat from the engine do you think the epoxy will hold. If you think there will be a problem I will buy one (just tell me what it is called) and I will replace it.
