Can someone tell me how to clean carb air filters?... Can you wash them in strong detergent, not foam filter but the ones like these

I use a K&N filter similar to that on my motorcycle.
There is a cleaning kit available that uses what smells like a mix of detergent and solvent. The detergent is not very foamy, so I'd suspect something like Truck Wash.
The trick is not to use an air gun, but to use repeated washing cycles.

Cheers for that, do you let them air dry in the sun?

I'll check out the cleaning detergent tomorrow.....

Yes indeed, air dry for at least a full day before oiling.
The last K&N cleaning kit I bought cost me $50 at Super Cheap Auto. It came with cleaner and oil.

That filter material looks identical to what I used to run on the Webers in my Datsun 1600 back (back way back) in the day.

I used to wash mine with petrol. Tipped a bit into a SS container, deep enough to submerge one side, hold that side in, shake around, watch all the deposits fall/flake off, then turn to next side. Container base would be chock full of crap by the end. Left filters to dry overnight then whacked em back on and away I went.

Petrol can dissolve glues and damage materials with repeated use. I used kerosene and then follow up with hot soapy water back in the day, but that was with foam ones.

Did it for 4 years on the one set of filters like pictured, on the same carbs on 2 engines. Zero problems. It was what the instructions said on mine.

Perhaps things have changed.

Spot on.
Cheaper than I remember too. My kit has lasted 10 filter clean and re-oils (100 000km).

I'd say it's good on that style then. :thumb:

I had trouble with aftermarket moto foam ones, but they did get washed a lot when I was riding weekly. The glue sometimes let go. When I switched to kero the problem went away.

 

[binner]

All back together

I'll let you know how the k n cleaner goes, the donk is back in its home with new ratio rockers and swivel feet so we shall see how it pulls now
Well, yeah had to go a bigger tacho now didn't I
Green engine bay is with led lights on green.. It's not always glowing like that..

 

[Elbo]

Finally got my coilovers in and new wheels on yesterday. Its come up another 2-3cm from this photo as it was scrubbing and the oil pan was only 7cm off the ground. This is my daily, so although I want it to look good, I also want to get into shopping centre carparks, and my driveway! I still need to put the flares back on, so that will change the look slightly. I'll wait until they're back on and see how it looks before I decide on a final ride height.

 

[binner]

You got the look

^^^^^^ dumped to the weeds,rims look sweet with the dump.....how is the ride now?

Thanks dude! Really happy with how it looks now. The ride's pretty rough, like an unladen ute in the rear, bit softer up front and feels responsive in the corners. Definitely finding the worst of Sydney's roads now. Potholes are easy enough to avoid, but those concrete slab style roads are horrible to drive on. Have a clunk coming from the front when turning the steering wheel at low speeds, so CV joints might be binding at this height. Will see if raising it another 1cm stops that or not.

Here's another shot.

I used to run a car workshop back in the 80's and had many customers with these.

Spray degreaser works fine (essentially what the K&N cleaner is).

Make sure the cotton is completely dry before you re oil.

Spray oil is easier to get complete coverage, but more expensive.

Either way hold filter up to the light and look through to ensure uniform adequate coverage (can take time, we used to leave them overnight).

If you dont do it correctly dust will get through and into your engine (when doing maintenance always pays to have a look down the intake system and wipe a clean finger on the inside surface to check filter efficacy).

For a sunday car and racing they are practical. For everyday use in a dusty environment they are a hit and miss affair.

I don't run them on the car or motorbike as a consequence of what I saw when I was in the trade.

Had been saving for a Transition Trans Am... Until this popped up. 1980 Ford Escort coupe, has been sitting in a barn since the late 90s.
Its going to take me years to get it where I want it. But the end goal is turbo cosworth, bare metal respray, upgraded braks and steering.

Ooooh, that takes me back.......cue flashbacks of being upside down in a table drain.

Going for a rs2000 look?

 

[Reece_STP2]

That sounds like a rough flashback, mate!
I think just the single round headlight conversion is on the cards. I hate the square headlights and Ive owned an rs2000 in the past and and couldn't bring myself to mock up a faker.

Still kicking myself for selling her.

Thanks for the details bloke, I used the KnN cleaner and it cleaned em up real good. That was the first clean since my donk build so it was about 3500 KLM and both filters were a bit funky. Should I be looking at foam filters instead?

From my experience in a motorcycle workshop, the K&N has the best flow short of chucking your filter completely. Careful oiling of the filter (as Redbruce said) is essential to protect your engine. Looking at your work, the kind of attention to detail you show is more than sufficient to ensure the job is done correctly.
