1980 ATC 110 Engine on 1975 ATC 90.

[wrecker200]

I have a very nice 1975 ATC 90 that is leaking oil very badly. I am not ready to dive into the job of splitting the case and fix the oil leak. However, I do have a good 110 points engine from a 1980 sitting on the shelf. I know the 110 engine will bolt into the 90 frame, however will my 90 carburetor, intake, and exhaust be sufficient for the 110 engine?

You'll need a 110 carb and intake but the exhaust will work. You'll have issues trying to rig up an airbox too. The 110 is roughly 6-10mm longer so the bolt up to the head mount will have to be adjusted.
