Beach Dude, I do not want to make it look as though I was trying to make you look bad when I posted. Just to be sure, if you have your original owners manual look at page #78 where it says capacity 1192cc. That is what is refered to as a 1200 engine @ 40 HP. The 1300 on the cover of the book and on the engine hood is what the sales department used as a model number for 1965. I just looked at an owners manual to be sure I was correct. I worked in a dealership from 1963 till October of
1965 (when I was drafted). If your manual says other than 1192cc I stand corrected.
