Air cleaner gap? please advise

Post by Bobert on Tue May 05, 2015 4:05 pm

Ok so I got a little air cleaner front the parts store to get me by till I find a better one. I put it on and it fit but there was a gap below it, seems like if air can flow in without going through the filter it defeats the purpose, am I right or is this fine. Here is a pic of the gap.
thanks in advance

NO, measure the diameter of carb, and go out and get the correct air filter with the right diameter

Alright, I returned that cleaner, but none of the parts places in town seem to have one that will fit, anyone on here who doesn't use the stock setup can you point me at what you are using to keep it running smooth?

Also I measured mine and looks like the diameter is maybe 2.75, so it's just a hair bigger than the one I originally bought.

What kind of carb do you have? I think Carters YF's are larger than Rochesters and Hollies, I have an old one that fits a Rochester and it measures 2-5/8", not sure they make a small one like that that will fit a Carter but you can make an adapter or in a pinch use some stick on high temp foil ductwork tape and a hose clamp to hold it on and seal it, but DO NOT run your engine without one, a backfire can ignite the doghouse lid insulation on fire if you have the old dirty oil soaked original stuff in there, I know been there and done that, toasted up a whole van back in the day doing this. Look on eBay, there are probably cleaners with an adjustable base available, but larger diameters hit the doghouse lid

I've used this one on Carter YF's, Rochester B's, and Rochester MV's with no problem.

OK, I did some checking for you....the small hot rod type air cleaners like above have 2-5/8" base mounts. The Carter? YF or whatever it is like in your picture is about 2.75"! You can simply buy one of those K&N type filters like this that has a 2.75 inside bottom flange:

But it may be too tall for the doghouse to close, either find a stock filter or make an adapter from some duct pipe, a larger hose clamp or a few tin cans, etc, be creative!

I'm assuming this is the original carb, other wise not really sure about the type. This is all the writing that is on it



Yeah, If I can't find something to fit I feel confident in my ability to make something to make it fit. I just want to give it my best shot at finding the best that I can first, I don't want to do this sloppy.

Hmm, its a monojet, but it may not be original. The top is unusual and might indicate the carb is off something older. Can you please post more pics of this carb? I've used these little air cleaners many times on my vans, on monojet carbs too. I suspect you might have an oddball carb there.

All my carbs measure 2.6 " on the outside of the throat. So that 2.75 is definitely weird.

Yes agree, maybe it was for an oil bath air cleaner and had a different top throat? I do know the Carters are larger than than the GM's but he clearly has a GM carb. Bobert, next time you host a picture, reduce the size to the 640 option in the dropdown box so we see it full width, the quality will be the same. Kooky, click his pic and then look at his next pic showing the top at his host. You sure that air cleaner you bought is not for an older 2" throat carb used on older hot rods? They make them in two sizes or they have a pop out spacer ring so they fit either size.

Alright here are some more pics. Sorry about the quality, clearly I'm not meant to be a photographer.













As you can see the air cleaner fits on, until it its the neck part, which seems to be the exact same size as the cleaner. It saide it would fit up to a 2 5/8 inch carb so mine is clearly a hair bigger. I tried to measure as precise as I could and its 2 19/32 inches. I don't know how much any of this helps, but I hope its something at least.

You are missing the "bridge" plate that goes across the top of the carb to mount the center stud on. It screws into the two holes inside the rim. Easy to find new or used, here's what it looks like:
