Engine sputtering at about 65

LOL... I initially read that last line as "perfect for gas tank explosion"...

Just keep in mind that as your speeds increases, the fuel consumption increases as the wind resistance increases. So low speed is less load and less fuel flow than at cruising speed, even at the same RPM's with a different gear. And sometimes the plugging up takes some time to show itself; the crud can fall off the sock when you stop and then build up again. It really does happen this way... and the best filter in the world won't change what is going on in the tank.

If you're gonna do the tank anyway, I'd do it now to get this out of the way. Then look into the carb again to see if things were plugged, and check the fule pressure at idle.

Fuel pump crapping out is certainly a possibility too.

I hope the fuel tank explosion holds off LOL. So this morning before heading to work, I cranked the initial timing down to about 12 ish degrees initial advance. It drove well at cruising speeds but did start to want to stall in traffic when slowing down to a stop, so I think it may require a little more than 12 degrees initial. I'm not sure of the total timing because there's just no way to gauge it with the way the block is setup, and it disappearing pretty much after 10 degrees of advance timing.

I'm pricing the fuel tanks now just to be safe. I do think the hose before the inlet of the fuel pump being so brittle and cracking so easily had something to do with the original problem and replacing the fuel pump, although it was painful was something that shouldn't harm anything, so I'm actually ok with having had to do that.

Something else that came to me is that maybe the fuel pedal travel isn't enough. I had to hack together a new cable for this to fit the lokar TPV cable that I had to install because when the original owner yanked the /6 out of this, they tossed the kick down linkage that was there originally. I'll have a look at that maybe tonight.

Here's a photo of the 2 cable installs.
