Wen-Mac .049 exhaust throttle spring

I need a picture or instructions on how the spring and throttle arm on the exhaust "throttle" plate work. Its for the flying platform that has a control wire and a throttle string attached to the arm.

Thats ok, it has a unique throttle adjustment exhaust port. The engine I have had been taken apart and therefor I don't exactly know how it goes back on.

The one I have had been taken apart and was just kind of put together. I am sure I have all the pieces and will have to just reverse engineer the arm, spring, step washer for centering the spring and the nut. The one pictured is also in a messed up condition with a bent arm and the spring looks to be not attached at the lower end.

I had this one handy, and think it's untouched as far as the throttle assembly is concerned. As you probably know, it's spring-loaded closed so a third line can be pulled, opening the throttle.

Hope this might help:
