Thanks ond! Didn't plan the color combo just how I found the engine guess it was meant to be. Weird how much the engine hangs off the right side of the frame considering this was the engine the bike was designed to run. It will even out once the clutch and guard are on the other side I'm sure. Still on the hunt for this air cleaner
and the throttle/governor linkage or whatever the bracket is called that once lived here

Found pieces I needed but now I'm not sure how to assemble connect together to make the governor operational a diagram would be great! Thanks

(It is a full size scan, you will have to go through photobucket to view it that way though.)
The arm has to point up and youw will need a linkage to the carb, this photo from a bike did years ago kinda shows that pretty decent:
And you do need to refer to the tec manual to know how to adjust correctly for the governor to work correctly
If you dont use the Rupp version of the return spring setup you will also need to get the proper Tecumseh torsion spring for the throttle arm.

Black engine was not a rupp, it used the torsion spring on the throttle arm part number 32923 they warped around that bellcrank/throttle arm
That spring that rupp used hooked into the hole midway up the edge of the engines sidecover, that is the alignment pin for the sidecover and the hook on the spring just goes in the open hole (pretty visible on the black engine pic just above that half painted strap sticking out.

Interesting information here.
If I may ask a related question- On some of my H35 engines, there is a metal plate 7/8" wide, 1.5" long screwed to the bottom of that throttle piece with a notch cut to prevent rotation. To that is a coil spring that serves as the throttle return spring. Was that used on mini bikes, and what genre or years would it have been used? I like the simplicity and smooth operation it provides on the throttle feel.

The later versions had that which were starting to be used in 1974. They do work ALOT better than the earlier torsion spring versions. I guess the kits are supposed to come with the spring and plate, I have only ever ordered one in my life and it didn't but I think I may have just got jipped :laugh:

Thanks for all of that Markus!! Since it is a rupp I feel as though I ought to hook it up how rupp intended it to be hooked up. That being said I just put in an order at black widow for everything I need to get the bike going 
I found the gas tank decal for the h35 there as well!! I was very happy about that
