Cub spark plugs

[Doug Ct]

Will my 50 cub start any easier with the autolite 388's in cold weather or should I just stick to my 386's that are in it,and it does NOT have a mag.

I doubt very much that there would be any difference.

The heat range of all plugs does not matter when they are at ambient temperature. (cold)
A proper tuneup, and fresh gasoline, Multi Wt (like 15-40 or 10-40 oil),Plus "O" ga cables, and good battery needed to get it to crank over well. JimN
