What's the process to clean a cast aluminum Holley 4010 or Edelbrock carb with the shiny finish? All seem to turn 5 shades of brightness over time: Big black spots, rough surfaces, dulling, etc. I was thinking maybe Eagle One etching mag cleaner? You put the stuff on a set of Westerns and they...

Thinking about a propane mixer for a motor. One of those common carbs that looks like a carb hat with a gas inlet. Anyone run one or have knowledge of them from a forklift? Saw the hot bench pic of all the Chrysler motors getting run in on propane(?) and it intrigued me for a test stand running...

Do you think a stock 65 tank could be cut and flanged for a drop in efi pump? I saw an efi retrofit one and it looked like it was adapted. Just a cleaner quieter setup than a inline frame mounted pusher ala Ford truck.

Anyone ever consider making an Idle-eze air bleed down the center of the carb body ala Speed Demon? Drill a hole, tap it for a screw in air bleed like from a bike fork? Instead of the common idle adjuster that throws the transfer slot out of whack or the destructive throttle blade holes. You...

I was doing some AM coffee research (aimless carb thread following) and ran into am interesting carb tuning story on a six pack. Seems this guys trailer queen was nothing but that on the street with a F'd up carb setup. They go into what they did to fix it and shed some good tips on what repairs...

Common carb on early 80's 4 banger rice. Darn thing idles with the mix screw turned all the way in. Its an NOS carb with maybe 1000 miles on it, but no idle baseline settings can be found. the vacuum readings can be altered with the mix screw from a nasty 14 to a decent 20 inches vacuum but Im...

Having trouble passing smog (high NOx) on a carbed pickup that uses EGR. I already cleaned the EGR system and there is no more charcoal in it. I need more EGR or cooler EGR as I milled the head a little more than recommended. Would it make a lick of difference if I ran my EGR through a trans...

I got a 4781 and need to know what the throttle plate clearance is in the bores. Mine look like they are .010 under as they dont seat against the bores. I have a 3310 750 and those plates are light tight when the throttle closes. There is nothing stopping these plates from seating and I have...

if anyone of you guys with lo output motors are running a Facet style electric pump (the "jiggler" style) that is cylindrical shaped (as opposed to a transformer looking thing) let me tell you what I found when I ran mine. Im idling my motor to get it hot for smog and the motor dies after 10...

Any issues running OEM style nylon fuel line for an EFI retrofit setup? No track duty. How does it get terminated? Pressed on fittings, clamps or shrink? Oem looks all shrink or pressed.

Found this and thought it was an interesting article, perhaps he is a member too? http://www.mooregoodink.com/news/installing-a-new-street-demon/#more-4997

drilling a carb for a charcoal can ported vacuum source. Does the size of the port matter? The one I need is like the size of a ball in a ball point pen but I dont have a drill that small thats 4" long. I thought vacuum was vacuum, cant regulate it? maybe put a small carb jet in the hose? Thanks.

Been following this guys build: SB Mopar, Weiand TR base and custom plenum and MSII. Lots of good info for the EFI guysgetting started....http://www.pro-touring.com/showthread.php?63646-EFI-Mopar-project air box is a little crude but you should see mine! ;-)

This is a well known formula for deducing fuel requirements for a certain power level..but I don't get it. "...In most cases a naturally aspirated engine will have a B.S.F.C of .50. This means that the engine will use .50 lbs. of fuel per hour for each horsepower it produces. Turbocharged...

Installed on a dog-pie chevy...285 hp/296 at the rear wheels on a carb...picked up almost 29/26 with the EFI and smoothed it out considerably. Dead head fuel line too, so no return line. Temp, O2 and fuel, thats it? How much? MSD Atomic EFI

Holley states "these should never be used on the street" Why? whats the deal besides J tubes and staked throttle shafts?

Bought a Bosch EFI pump for an EFI conversion out of the scrap yard. Snagged it out of an 86 MB 420SEL or so. External pump, inline..perfect or an EFI conversion. Well, should have bought the 4 buck insurance because the thing was seized beyond hope. So what to do? Dissect it! Wondered how...
