    Timing and Dieseling

    I really appreciate this. I know I've read all these on here before but when it becomes my problem the ideas seem to hold more weight. I owe 9/10 of my knowledge of these engines to this site alone so again, thank you. I'll replace that one plug wire tomorrow and retard the timing and see where...

    Timing and Dieseling

    I'm surely going to back it down... It seems to run too rough at this point. Will any of this cause it to run cooler by chance? Just curious.. I haven't seen it run hot or anything, it just seems to get warm really quick Sent from my SM-G935V using Tapatalk

    Timing and Dieseling

    It's an 85 so no fuel injectors (I say that since yours is an 87) but I'm sure you picked up on that. I have the dizzy adv plugged, and all other vacuumed ports plugged except the pcv, brake booster, and choke. Those are all hooked up and the choke is on the manifold port. All emmission items...

    Timing and Dieseling

    I reinstalled the rebuilt carb, installed a new dizzy, rotor, plugs, and wires, found/fixed a valve cover leak, and set the timing at 12btdc. Engine ran at 750rpm. Idle screw backed all the way out and then screwed just enough to move the throttle (to achieve the ~.050" transfer slot), and I'm...

    Holley 4175 rebuild

    EDIT: DUMB QUESTION. OBVIOUSLY IT FITS LIKE A GLOVE! PSHH EIGHT DOLLARS GFY OK I finally got this thing put back together but ended up with gas leaking from the transfer tube. I pulled out the o-ring and it was missing about an eighth of the ring. Not sure how that happened since I used the...

    Fuel line adapter

    Fuel line adapter

    Yes that's how they referred to the OD. That's why it took me a while to find what that spec actually meant. I found that I need a -6AN fitting for the AN hose fitting I have now (OD HOSE for a -6AN is apparently assumed to be 9/16 which is where the -9AN came from and is the typical ID thread...

    Fuel line adapter

    I think I ended up finding the correct parts?... The hose is -9AN OD with a -6AN ID. It's very strange because the description says it has -6AN fittings but the ID of those threads are 9/16 (-9AN). So I ordered these -6AN to 9/16 fittings. Honestly have no idea if these are going to work... Not...

    Fuel line adapter

    I'm replacing my aluminum fuel line with a braided steel line. Braided line has AN-9 (9/16) internal thread fittings on both ends... I need to adapt it to what I believe is a 5/8 internal thread for the carb and fuel pump. I went to both advance and O'Reilly and neither had anything. Is this a...

    Worn Rear Shock Mounting Hole (Slotted)

    Hey guys, my truck bed has been sagging in the passenger rear side so I went to check my Suspension and found the shock on that side was about 1.5" longer. That shock mounts angled towards the cab. Anyway, while removing the shock I noticed the stud was a little loose and then found that it had...

    Vacuum

    Mine looks like this right now but I would also like to know how I should set up my charcoal canister... anyone got any clue where each hose goes? Ive labeled the can ports 1-4.. Yellow are my current vacuum lines.

    Holley 4175 rebuild

    LOl never heard that.. Im a mechanical engineer and design for a living so it makes me almost cringe to hear. Always worried about stripping helicoils or threaded inserts. But, the real reason I ask is because all of the material used on these feel so soft. Thanks for the chart. That thing is great

    Holley 4175 rebuild

    Alright I hope I don't junk up my whole thread but I have a few questions, 1. Is it ok to soak the vacuum choke "bell housing" in carb cleaner? It looks like it doesnt come apart 2. Does this throttle linkage/plate come off? Ive removed the "2" screw and and the link. I was thinking maybe Id...

    Holley 4175 rebuild

    Ah. My bad. Im new to all the terms so thats my fault. Yes, metering block. I know theres an idle circuit in there so I just made up a new name and stomped my foot about it. Appreciate that.

    Now that I'm looking closer at that picture.... Those cracks in the plate can't be good right? Or am I seeing some weird lighting.. Sent from my SM-G935V using Tapatalk

    I suppose it could be a flat head but with everything being either AL or brass, I'm hesitant to put too much torque on anything. Sent from my SM-G935V using Tapatalk

    I'm talking about the idle circuit plate (bottom of image in kitty litter box). The secondary plate has different screws though... I thought I had seen and had every screw tip there was until I saw this one... What is that? Sent from my SM-G935V using Tapatalk

    Holley 4175 rebuild

    Thanks. I was cautious about it tonight since it was getting late and the bourbon and beer we're getting in the way. I was running out of room on my rug too. I'm having trouble getting the idle circuit plate off though. Any tips? I've broken a few razor blades trying to pry it open along with a...

    Holley 4175 rebuild

    This is my first carburetor rebuild so I figured I share/document. Here's the first night of breaking things down. I'll try to edit where necessary and can post more of a progression "album" if anyone cares to see. Heres a summary of the parts so far.. Sent from my SM-G935V using Tapatalk

    Timing and Dieseling

    Holy cow, thats a chunk of change. Im looking at a $56 Balancer and then check out your Fluid Dampener for $230! Whats the benefit here? Just extreme reliability?

    Timing and Dieseling

    I like the look of a braided one and it seems easier to install so Im on your side. The only reason Id justify another solid line is that I dont intend to take the carb on and off and wouldnt mind saving $20. I welcome part suggestions.. maybe even with a filter/gage combo.. I like to make sure...
