Sorry, Dave, I don't know.

I'll make a point to look at it closer next time I have the cowl off. (Hopefully a long time.)

I did get one from ACS for my project plane that was a nice little one like that...

Larry,

Thanks for the reply...but leave that cowl on as long as possible!...You have suffered enough.

Also like to thank you for posting the comparison on the carb sockets....I am up for replacing them this summer and based on your report the non rotax ones look like the ticket.

Sincerely,

Dave S

The manufacture of the JBM sockets is better mainly due to the sealing surface being more consistent and having less rubber on it. This allows the socket to be installed flatter, more parallel to the manifold face. I think this gives a better seal on that face.

Also by installing the socket, then the carb to the manifold "on the bench", then putting the assembly on the engine, this allows for a more precise assembly of these parts.
