spark plug question

J Hamilton · May 1, 2022

I just got an Oliver 88 and was told it has a 1650 engine in it. What spark plugs should I use in it? I have read there are long and short thread plugs used in these. I can't read the number on the old ones. This is going to be a working tractor, not a trailer queen

It takes a7/8 socket to take the spark plugs out of an 88 head and a 13/16 socket to take the plugs out of a 1650 head. More questions?

I called Korves Oliver today and gave them the casting numbers on the engine, it's actually an 880 engine in it. They gave me a plug number to use. I'm sure I will have more questions about it. Thanks
