Fun and Games with a used Edelbrock

Post by Chorlton »

Friend of mine bought a used Edelbrock from the US a few months back.
Hes going away for a few weeks and I said I'd clean it up for him

HOOOOWEE
This thing has so much junk in it its amazing. Both Rods are stuck down and the jets in the float chambers are clogged up with so much junk I just dont think it would be worth it.

Be warned !


Be very carefull as the leg you bite today could be attached to the arse you have to kiss tomorrow.

Hi
You need to get your head around the US citizans attitude to the car, an average old car in the US will be 3 years old and have done about 80 to 100k miles had 2 to 3 owners and will be ready for replacment, a really old car will be 6 or 7 years old but will probably have only done 100 to 120k miles, most will have had two or three filter changes and the oil changed about twice as often. There is a federal requirment for a major servicing that involves things like plugs abd cam belts not to happen before 100K miles and I think it goes for brake discs and stuff like that. this coupled with much cheeper build standards and cheeper materials used result is most cars are dead by 4 years old (ie they are scrapped before the first big service). As a result a carb really only has to survive 3-4 years, they are so cheep anyway it is easier to replace the carb than reset the idle circute (most carb adjustments are blanked off on OEM spec carbs anyway)
Yes they are junk, in the sort of ues we put them to, fewer miles over a longer time) they become so corroded inside they are junk by 40K also a 4 barrel is built to a budget of about a 1/4 of an SU (they made 10s millions of the things a year when every car in the US had a 4 barrel on it) and probably an 1/8th of a webber. There is also a big differance in mas production techniques in the US and europe, the US use a different philosophy to us in that they use relativly wide tollerances then select in batches ranges for components that will fit together. That way you can extend tool life and still throw fewer components away, you just cant always interchange so many components (hence the good old Chevy interchange manual)
Sorry long blurb
Best regards

Haha yes thanks for that Mike
Just been playing with it again and one of the Step Up pistons is jammed solid. The other needed a nudge to move it, but the other is solid.

I might suggest he get the beast Ultrasonically cleaned, that should sort it out.

There are a few companies in the US who make copies or these carbs to proper tolerances and out of decent materials, using better production methods, you could just bin it and buy such a carb, he would thank you for it in the long run!

Pan scourer and a dish washer then and a few brush-picks to clean out the holes.
Best regards

I still cant shift the stuck Step up piston.
Its been soaking in WD40 all night but still no movement.
Tried tapping the rod but that wont budge it.

Not wishing to sound defeatist, but are you sure it is worth the effort?
I think it might be worth at least investing in a new metering block if it is that stuck, the jet the metering rod is in is probably furred up aswell and the passages behind it, it certainly won't be the intended size by the time you have the old one out.

I got the jets out OK but its just the actual rod piston jammed into the top half of the carb. The rod is free and moving in the top section of the piston, but its the damned piston thats stuck.

Ive not got much to do at the moment as Im waiting for stuff for my Cobra.

These will help. They do rods and jets as well. Price and shipping is very reasonable.
