So now that the secondary vacuum is fixed, she's little hard to start, but when I get it up to temp the choke stays closed. I let it idle for 20 minutes and the choke is still closed. So I propped it open at temp and gave it some throttle and it just fell on its face and stalled. The MAS was out 5 turns from completely closed when I started this "diagnosis". The questions are: 1) it appears there is linkage for the choke to hook up to but mine isn't. Anyone have a picture of one hooked up? 2) what is the settings for the MAS? I'm at sea level if that helps. I'm guessing the previous owner was trying to comprimise the mixture for the secondary diaphragm not operating and the choke staying closed. Any guidance that you guys can decipher out of my ramblings will be greatly appreciated.
