Great starting became hard starting.

Pulled carb and took apart. The secondary needle and seat looked fine but put new one in anyway. Cleaned up everything and found the air bleeds on secondary were partially plugged. Cleaned everything up. Installed a 1/2" phenolic spacer with the 4 holes. Cleaned out fuel filter. Set primary transfer slot for a little past square. I then counted how far I can open throttle and be at .040. Put back to almost square. I then did not know what to do with secondary transfer slot. It was completely closed. I open it slightly but not up to transfer slot. Assembled everything. Set idle mixture screw 1.5 out. Cranked to fill bowls with no spark. Then gave it a pump and it fired right up. Idle about 1100. Let warm up and released fast idle. Died out. Opened idle screw to .040. Still to low to idle. Gave it 1 to 2 turns more and was enough to idle. Checked primary float and was fine. Secondary float was high so I cranked down a bunch. Tried setting idle mixture but screws did not do much left at 1.5 out. Vacuum is down a little about 17. Took for a drive and ran well. When I got back secondary float was low so set to just below hole. Shut off and car dieseled a little. I did not look at idle speed when I shut off. Waited a bit. Started right up. Idle was a little high, turned down to about 800. Turned off and was fine.

Messed around cleaning up. Checked a plug just for the heck of it. Tan to a little rich. Was a little lean before. Fired car up idled fine. Took for a short drive. Ran fine. I think the spacer helped the mid range but took a little off top. Came home and shut of and dieseled a little again. Temp was about 195.

So the starting problem seems fixed. Will see tomorrow on a primed fuel system and cold engine. Now the dieseling. Is it caused from to much idle and throttle being open too far? Where should the secondary be set with vacuum secondary and 2 corner idle? I was gonna switch to EFI this winter, but car is telling me now is the time. Plug fell out of bung when driving, carb issues. I just hate spend more money now and this is the best time of year for driving around here.
