Problem of the day...bloody car won't start when hot (searched the archives - useless SU HS6 on a B18). Anyway, I've spent some time trying to get the mixture set correctly following all of the recomendations etc. First it will not cold start and seemed to lean backfire (pop) then would start...so I richen the SU's a couple of flats and that seems to get better. Now it won't hot start.

I was at the parts store today (about 10 minute drive) to locate the oil seal for the OD that I need, and when I tried to restart the car (sat for 15 minutes), it would not start. I had to sit for 40 minutes and let it cool off, then it fired up and ran fine. This is getting a little embarassing. I tried to floor it when starting etc...no dice. The only thing that works is letting it cool until the temp gauge reads just below the first line by C.

I pulled the air cleaners apart and fiddled with the mixture again when I got back to the garage, but I don't think it made that much difference.

The ignition system is still stock (stock coil) and has new plugs, wires, cap, rotor, is set to 10 degrees BTDC, it is not vacuum retarded, and works fine (checked total advance with a dial back to 0 timing light - total advance right on spec). About the only thing I haven't checked is the dwell (can't recall how). The only way it likes to run is really rich.

Any brilliant thoughts? This is getting frustrating.
