Clean Air Filter

[LynnLegend]

Hello,

Further to a thread I had posted in general chat, my a7 is running jolly rich. My first port of call is going to be to clean the wierd air filter, Haynes recommend petrol and then some 20sae oil, I wondered if you chaps had any other suggestions?

If she's still running rich I'll have to start playing with the carb itself, but wanted to clean the filter first.

Thanks,

Sam.

Maybe that filter has seen its best days.

I think they were about 58 years ago

That type of air filter is quite rudimentary just several layers of gauze and nylon like material. The factory owners manual says wash in petrol, dry and replace.

Haynes is not always helpful.

I'd be happy to replace it, would some foam cut to shape be any improvement? Alternatively could anyone recommend where I could buy a new element from? I don't want to replace the whole unit.

Maybe these people can help you out?

They also sell foam material and gauze to make your own

Just fitted a nice one to my Amal 376, bought from Andrew at Priorymagnetoes  About £14 plus carriage.   
I think has others.

If you want to keep originality you could do what I did, I bought 2 sheets of copper mesh off ebay not expensive the finer mesh was I believe about 120 that is 120 holes to the inch the coarser mesh was 20 mesh ie 20 holes to the inch. Cut 2 circles of mesh tack soldered around the edge, then fitted into the existing perforated plate with the finer mesh against the perforated plate sealed the edge with silicone sealer. coated with some thin oil blew the excess off then fitted back on the bike works a treat.
