It was a '75 Westy. It was either spend $400 on an ECU, which might or might not fix the problem, or $300 on a Weber progressive carb kit, which would. I put the carb on, and it ran sorta okay, but I probably wouldn't do it again. I had to tinker with the idle jets to get it to run right. Had a big flat spot coming off idle at first. It always idled a little rich (if you adjusted it so it didn't, it would be back to having a big flat spot) so if you let it idle too long it would load up. It would never have passed smog in any jurisdiction. In cold weather those long, unheated manifold legs would ice up and it would run crappy. Top speed was down from what it was with EFI. Fuel economy was about the same. The noise level went up a bit because the tiny air cleaner that came with the carb didn't muffle intake noise at all. Stepping hard on the throttle at low RPMs would cause massive bogging, because the engine just couldn't take having the secondary barrel open at that speed. Most of these problems could probably eventually have been corrected by carefully tuning the carb with a tailpipe sniffer...but then you're back to needing expensive tools again and you might as well just run EFI.
