We're all hiding in the garage from a solid day of non stop rain. Been trying to research some information but no luck. I acquired this set of carburators, the choke lever and throttle stop screw were missing. I was able to solve the choke lever problem, but nothing for the throttle stop screw. Anything on Ebay is like $25 for one liitle screw sent to Canada. Does anyone know what size this screw is? A metric thread pitch guage, has a fit of .5, very fine thread. But what size is the bolt? Is there anything else I could use in place of that missing screw? I do have the spring for the screw. I thought about a machine screw double bolted on each side of the bracket, but there would be no easy adjustments made with that.
