>Also need plug type and gap for 1988 Honda SB50 .Is there and alternate
>brand as well?Thank you
I'm not familiar with a Honda SB 50, but almost all Honda 4 strokes like the
SS50, CD50 & others use a NGK C7 HSA spark plug. Most Honda 4strokes here in
Holland are tuned with 70CC engines or more; in that case it's usually
better to use the colder NGK C8 HSA plug.
Do you have a picture of that SB50 by the way?
