mat in tn Posted May 4, 2022 Share Posted May 4, 2022 Got the carb pulled off - are the nuts supposed to be that easy to take off? Barely took any leverage to break them free. The fuel line from the fuel filter took much more gusto! (Probably a good thing) Looking at the spacer gaskets between the carb and the intake, I'm wondering if the one that goes from intake to EGR (?) spacer has ever been replaced. the carb mounting bolts are a mystery to some. as far as how tight? tight enough! seriously though we have to remind ourselves that there is a soft gasket between the egr plate and intake with a high temp core because it is really an exhaust gasket after all. then there is the 1/4" thick gasket between the egr plate and carb. then the soft metal carb throttle plate. snug on a good gasket is all you want. too tight and you run the risk of breaking an ear off the carb. snug and evenly tightened and I always do a criss cross tightening pattern myself Link to comment Share on other sites More sharing options...

I'll probably at a minimum swap out the one between the egr plate and the intake - it honestly looks like it's been there a while. Later this summer, when my garage is cleaned out, I'm going to likely pull the intake and put in some fresh gaskets there and the do the valve covers as well. Half tempted to swap in dual plane intake so I can go to a 4bbl or a efi kit. Glad you mentioned the criss-crossing - that's exactly what I did as well. I saw there was some contention on the forums about how tight. I got them snug without going too tight and left it at that. Biggest concern for me was the fuel leak from the power-valve. Got what is supposed to be the right 2-stage for my carb (E4TE-AKA) and swapped it in. The power valve that was in there was not very tight after all either - so that might've been the cause of my leak. Link to comment Share on other sites More sharing options...

The fittings I'm talking about were barely even finger tight - especially the Power Valve. So far, so good - no leaks from the power valve cover going to the Ported Vacuum on the intake! Somehow the lead from the starter relay to the starter got loose again - this time the bottom nut. Got home and parked after taking it for a drive to the hardware store and realized I needed to back the truck up some more. Wouldn't turn over - popped the hood, moved the lead a little bit to make sure it was snug at the moment and the truck turned over immediately. Haven't driven it this weekend, originally we were supposed to go drive up and buy a Bronco but the seller sold it out from under me. Gotta love the lack of integrity. Back to the drawing board on that one. Old Red is enough of a project at times as it is! I ordered new gaskets to go between: -EGR spacer and Intake (FEL-PRO 60528) -2x Carb to spacer gaskets to go between carb base and phenolic spacer and then phenolic to EGR spacer. These suckers are thick though! They're FEL-PRO 60716's, I was expecting thin papery style gaskets like what was on the engine already. Has anyone used them? I may have ordered the wrong thing for those two. The EGR to Intake is correct! Link to comment Share on other sites More sharing options...

Working on the truck again after getting it back from the body shop - I had them address some rust in the fenders and cab corner that I wanted to take care of before it got really bad. They even cut and polished the truck at the end - looks awesome. Now I'm doing the PMGR starter swap (great instructions btw Gary!). Question - which terminal does the fusible link go to? On the original 3 post relay, turns out the link was on the terminal going to the starter. I replicated that but figured I should ask the more knowledgeable folks here. I saw in the photos on the PMGR instructions that it looked like the link was on the battery side terminal of the relay. About to go under the truck and do the starter swap, figured I'd ask about this before I just try to crank it over and fuse that link... EDIT: Never mind my queastion - I went and looked at the photo I took of the original relay and saw the fuse was actually on the battery side post and moved the link. Truck turned over readily and I eventually got it to start with enough foot pumps. (It'd been sitting a couple weeks) Link to comment Share on other sites More sharing options...

With a PMGR the starter cable moves to the battery side of the fender relay and the starter trigger goes on the switched side (that used to be the starter cable attachment) Link to comment Share on other sites More sharing options...

I think I saw in one of the diagrams or discussions that it goes to the ignition. I double checked the photo I took before I took anything apart and realized that the link was on the battery side terminal of the original 3 post. Got it all buttoned up and have to say, that the difference in effort to spin the engine is noticeable! Cranking for a solid 30 seconds didn't start to slow down or run down the engine. Had a bit of an issue restarting to the truck after I got it running but I think that was a fuel supply issue because a light feather of the throttle when I turned the key got it to turn over and stay running.

Black/orange perhaps? That would be the charge cable from the alternator or the shunt . All these trucks never had anything attached with the starter cable. All fusible links go to the battery side.

Got it all buttoned up and running. I'm blown away by how much lighter the new starter is from the OEM one that was in there. Link to comment Share on other sites More sharing options...
