Does anyone know the proper plug and gap for this motor? Also, what is the premix ratio? Thanks...Sid


This is a 7.5 hp motor.

"...Very early engines were 16:1, then it was 24:1, and finally 50:1 (this switch was in the 60s I believe)."

Depending on the HP of your motor... .030 should be a good place to start for you gap...

***EDIT***

Scratch that! I am reading from .060 to .090 on a chart I found; http://www.newbridgeauto.com/download/AJK_Spark Plug Application & XRef.pdf

Scroll down to the outboard section near the bottom.
