The dreaded reman

(1/2) > >>

I have a 17057253 that I was going to rebuild but not so sure now after discovering it has been remanufactured at some point.  Not sure the base plate and air horn match the float bowl.
The air horn casting number is 17053731 and the base plate casting number is 7041455.
Looks like cheap parts inside, no numbers on the jets or rods, lead plugs in the bypass holes, etc. Anything else I should look out for?

matt68:
Any info at all would be appreciated. Thanks.

After messing around with a few remans, including a couple of the "name brands", I would just check ebay, craigslist, and local yards and swap meets to find a rebuildable, unmolested core. You will be headaches and dollars ahead. Use Cliff's parts and expertise when you have questions. If you can, find a later 70's early 80's core as they are very adjustable to your engine's requirements. Good Luck! ;)

I do not like working on them here, and do this for a living.  Doesn't mean you can't get one to work, but the quality control these days on them is pathetic, and they can be problematic and labor intensive.

About half show up with no fuel inlet seat threads, so you're dead in the water right out of the gate.

They also "butcher" them up, miss-match parts, and subject them to some sort of acid-bath cleaning process that leaves the castings "soft".

WAY better to just get an unmolested core right to start with........Cliff

Thanks for the replies. Looks like the one I have was rebuilt a long time ago.
Other than the plugged idle air by passes, nothing looks too butchered.
Inlet threads are good. The castings look like they match up other than the part numbers,
they are kind of rough though. Looks like they were sand blasted.
I am sure I will have other questions as I get deeper into it.

Thanks,
Matt
