RE: Blasted spark plugs? I've got a set of blasted plugs in my SBC in the dragster now that went 4.98 @ 139+ on gas a couple of weeks back so yes they will work. ;-)

That is very ironic. I read your post about cleaning up your plugs a few hours after you posted on this topic. I think that I will plan on a one shot WOT and read the plugs. I am also pondering cutting out a fuel pump block off plate and installing the electric one in line at the same location just to see if it is running out of fuel. I know it would be better as a pusher, but this would be an easy install and test. I do need a pressure gauge. Have always wanted one, never got around to it. I even gauge the temp on my tranny, I love to see exactly whats going on. The more I test different power valves the more I think they should be called an idle/cruise valve. They are out of the equation as soon as any real action takes place. I have been running 4.5's on my carbs for years. I was told that it was better to clean them up and lean them out faster. Now I am not so sure, maybe my old 650 would idle better with larger power valves.

Just primer

Scratch that. Wouldn't affect the idle, only the transition just beyond idle.

May have found something. Was inspecting the secondary pump housing and the fourth screw was beginning to strip. Replaced it with a longer screw. I do remember feeling that almost tight almost failure on that housing. Still want to read the plugs on one run and see where I am at. Found another rubber pump in an old Carter rebuild box that I had. Must have misplaced it years ago.

Just primer.
