Super Rat parts?

[SuperDave]

I got a blown Super Rat, too hot of a heat range spark plug blew a hole in the piston. Now I'm looking for a new slug. Anyone know of an American vendor who stocks type A pistons?

BGF and Rose326 both sell parts I believe...just be sure which piston you order.

Do Super Rat and Skyhawks have different pistons? They come from different factories.

Looks like bp6hs to me.

Greg58 is right, it is a BP6HS plug. Too hot for muggy Florida. Next motor will use a B10HS. I also have an 8 & 9 plug.

CARider, yes they are different. Rats have a longer rod and thus a higher wrist pin hole.
