Hi all
I have a 25hp 1985 Evinrude and am wondering the recommended mixture ratio.
I ran the engine for 3 hours the other day with brand new plugs using a 50:1 ratio.
I whipped the plugs out today and there was quite a bit of oil down in the core of the plug. The electrode wasnt too fouled but some oil residue around there.
Could i go to 100:1 ?
Should there be the amount of oil left on the plugs that there was if that 50:1 is the right mixture!
any advice grateful
thanks
