My Honda 4 wheeler needed a tune up so I bought a plug, oil, oil filter and air filter for it last week, it warmed up yesterday so I tore into it. All went well the spark plug needed a very thin walled socket but I made one for that job. I went to change out the air filter and it was jello like and melted on the metal tube that runs through it?

I sprayed it with starting fluid but that did now eat it up I will try carb cleaner next then acetone unless any of you know what eats that foam material up.

Any clue?

is it in a plastic housing also ?

acetone and some cleaners are very hard on foam , but probably took time also

I assume your trying to get the old stuff out so you can put a new air filter in

remove the housing and scrape clean with a razor blade would be my next approach if possible

Metal perforated tube the filter goes around but itís a plated metal, the stuff looks like itís breaking down like picking up hot butter.

Replace it.

No matter what you do unless you get it perfect , you will have restricted air flow. Plus the possibility of chunks/bits getting sucked into the engine.

You would not want a dirty air filter , same thing.

Donít know what could of got into the box itís in a box with clips, it would not start so it did backfire a few times (bad plug) and I could smell gas. Iíll clean the tube and put the new filter on it one way or another Iíll get it clean. LOL

If you ever sprayed a foam cup with carb cleaner you would understand what Iím hoping to find here.

Foam filters will all of a sudden break down at a certain timeframe. At least you caught it before it got sucked into the engine. Rocky Mtn ATV will have the part.

Tough choice between a $40 carb or $80 tube if I replace that. Iíll try the carb cleaner the brake cleaner I have both on hand the parts cleaner or gasoline will be next. Iím in no hurry.

Will keep you posted on what works.

I may be misunderstanding the concept but would steel wool shine up the tube?


I know I'm paranoid......but am I paranoid ENOUGH???

I will most likely wire bush it or steel wool in then blow it out with the air compressor to see if I can get where it needs to be to go back into the ATV. The main issue is this glue like melted foam that needs to come out. I will check the junkers at the farm, maybe I can find a clean one in a dead 4 wheeler!

I got the loose jelly type stuff off now it is more caulk like it scrapes off then leaves a thin layer blocking the tiny holes but the carb cleaner seems to remove most of it Iíll keep at it I have cams to put out today Iíll let it soak until tomorrow then spray it again and air blow it out. Itís getting there.

I am wondering if gas might not be what happened to it. Our Honda is leaking now and will put a new carb on it rather then fight the float or whatever problem.
