Hi,
The distributor for a 1098 is a 25D4 - which 25D4? Is there somebody that can give me the other numbers please so I can look for a S/H one. Also does anybody know if a DM2 can be used in place of the 25D4. I cannot find any sheets anywhere that list either types for 'A' series engines. Thanks in advance - Nigel

dont know about those numbers, but i have many second hand ones.

The manual says that it is 25D4 numbers 40849B for high comp,
and 40899B for low comp.

What do you consider to be high or low comp?

On the 1098 engine the high comp is rated as 8.5-1 and the
low comp as 7.5-1. the engine numbers for high comp
begins 10MA-U-H.......... the low comp begins 10MA-U-L.
Self explanatory I think. The quoted compression pressures
are, 150 lbs per square inch for High and 130 lbs for Low.
