No Air Filter

[Landie]

Hi All,

I have a S6 Barrel back with a 1600 pinto and it looks like a Cortina\Ford carb, but it doesn't have a filter on the carb and there's very little room to fit one, between the bonnet, is it okay to run it without a filter?

Thanks Phil

Without an air filter you run the risk of dirt being sucked into the carb and the engine. If you can fit a filter somehow then you should. A simple foam type would do.

Thanks Hawknorth

I probably agree, just finding a very thin type of Pancake filter or cutting a hole in the bonnet, which I don't want to do!

Maybe a mesh type filter that I have on my Triumph bike?

This is a suggestion, ive not tried it. Firstly use a long straight edge, say length of baton between scuttle top and nosecone edge to measure how much clearance you actually have. Then look at at thin universal pancake filters, like https://www.ebay.co.uk/itm/311892226985 to use. Such a filter could even be made thinner by trimming the sponge and cage, but obviusly too thin will strangle the carb. The other challenge will be to find a way to mount it on the carb. You could cut a round hole a bit smaller, say 20mm, than the inlet diameter, then cut lots of radial slots round the circumference, 10mm deep, then bend each out at right angles. This would let the filter base slot over the carb inlet with a jubilee clip around the all the bent down bits to fix it to the carb. Perhaps some tape around this would then make an air tight seal. The filter could be mounted upside down so that the dome nuts are underneath, leaving a totally smooth upper surface.

Just an idea not sure if work but use ram air filter sock like for a trumpet/Weber/dcoe carb to sit on top as cut it down etc if get right internal size to match up. something better than nothing to stop any dirty and crap getting into engine.

Try this item number 335129751395 on Ebay. You'll need to know how much room you have of course. I searched slim air filter.  there is a few bigger ones that could be cut down and the end plate just clued back on
