Hi Paul,  Please see the attachments I"ve created one Slide throttle with Aluminum spacer.  If you like what you see I'll ship this one to you. For evaluation and testing.  Let me know what you think.  T.W.

Looks good. I need to retrofit one complete unit so I need at least one cover with
1-7/8th holes instead of two inch holes or no big holes at all.
(I can cut the 1-7/8th holes on the mill) The other cover can and should
have the two inch holes. This is for Mark's p-port engine.

Can you arrange that?
