I see that the adjusting screw at the top of the throttle valve piston is screwed wayyyyyy in. I was under the impression from the manuals that this screw was suppose to be flush with the top of the piston. My question: Is there any reason why someone might have screwed it in so far? Should I be looking for any subsequent damage from it having been this way?
This carb has a plastic bowl and it came with no gasket. I assume there should be one?
One other thing I about this carb is that both the carb to block retaining fitting and the top of the throttle body that the throttle cable threads into are Bronze? My other two carbs are not such. My instinct is to switch them out and put the yellow metal on my beloved yellow metal minty engine (precious). Seems odd that they would down graden aluminum throttle piston, plastic bowl and then then change those little bits to bronze? Maybe they came from some other gull?
While I am babbling this engine also had an Aluminum exhaust tube. Was this stock or did someone make it at somepoint? This engine suffered a tragedy at some point as I found a crack in the magneto plate $

One thing this project has taught me is that I like the older gulls much much better. Think I'll avoid the 70s from now on. brass tanks and villiers coils only from here on out.
