I'm trying to repair a continental au8 that belongs on a DB tractor. I'm missing the governor actuating plunger. Does anyone have a close up picture of one and the exact dimensions? I'm hoping I can make a replacement. Parts are impossible. Thanks for any help/suggestions.

I have a continental au8 also missing the governor plunger.  Not sure, but I believe the original was made of some type of fiber material . been thinking of making one out of piece of aluminum round stock, not sure of the length . Good luck.

I thought I'd post a picture showing where the missing plunger fits. Still hoping someone out there can post a photo and/or dimensions on an actual governor plunger from their engine. Thanks so much for any help.

Can the plunger be removed to get the size by just taking off the cap ?

Pretty sure that is the case, yes. The plunger should be sitting freely in the center post right beneath the cap. Thanks.

Part of a 1/4-20 brass bolt  , just a little shorter then 7/8"  ( 55/65"  )  I've never even tried to start it so I can't be of any help to how well it worked

Interesting. Thanks very much. I also got a reply from someone else that said they made one out of an aluminum rod. 3/4 long by 13/16 diameter with a rounded top. I think the original equipment was some sort of plastic or fiber rod.

Makes me wonder why the OEM plungers were changed/missing  ,,,  maybe the original ones wore to the point that it the governed speed was off ?
