Well, I assume it's fuel supply related, but that's why I'm here. Runs great, but after going 70mph for about 20 mins it starts choking. As long as I push the clutch in for a few seconds it will come back. The longer I have the clutch depressed the longer it seems to go without choking again. Initially, slowing down a few mph helps it last longer, but eventually even going 50 mph it will choke again. The only thing that seems to help is pressing the clutch or stopping altogether to let it rebound. I just replaced the fuel pump/sending unit and the ignition coil. Yesterday I also noticed some gas pooling on top of the intake, so I'm wondering if it is a carb issue. Any ideas?
