Shot myself in the foot!! Monojet :(

[BMERDOC]

Ok. So I got tired of messing with the old carb and found one on eBay. The 250 in my truck is a '77 model. I bought a Monojet to go on an early '70s model so I had to change some stuff. One of those things was the throttle return spring bracket. Well....somehow I lost the valve for the idle compensator in the process. I just discovered it when I brought the carbs into work to modify that bracket to make it fit. Any one have a junk Monojet I can steal the valve from? Its 29 in the diagram. I'll do what I need to to obtain one. Thanks!!
