Hi,

I've done the same thing !! And have tried placing a normal screw but still have a small leak.. can anyone suggest where I could source this screw or governor as a whole piece ?

Much appreciated!!

I could suggest a place if you're in Brisbane Australia that might be able to help. They rebuilt my pump and did an excellent job:

Thanks for the quick reply, I'm in UK unfortunately, shipping might be quite expensive !!

Just did the exact same thing and had to run back to a bigger town to get tools to remove the bolt. Anyone happen to know the length and thread of the vent bolt?

Found it.

Question: can I simply replace the anti stall device (items 1, 2 and 3) with a plain old screw of the same thread along with a washer to seal it all off?Attachment 156304

I have this identical problem on my Morgan 383. Thanks to the person on the thread who recommended Transatlantic Diesel. Just ordered the assembly for $80. I'll keep the old one and try a regular screw as a backup.

Remember to leave the setting untouched when you remove the old one (as long as you only sheared off the vent screw. Match the new assembly setting and reinsert so you don’t have to go through the whole process of adjusting the anti-stall.

Strictly what I as an amateur did: I screwed the anti stall screw in to about where it was. Start the engine and adjust until the engine revs where it should on idle (my 4-108 is about 1000RPM). If too far in the engine will cut. If too far out you'll have a screaming engine!

The problem is I don’t know where it was before it got moved somebody else and did it

Approx 3/16” of shaft exposed.
