B40 Star air filter - what's the best option now
« on: 08 November, 2017, 21:21:30 »
I have no air filter on my B40 star and on googling you don't seem to be able to get a copy of the original filter unit that goes inside the battery compartment/behind the air filter mounting plate.

The carb is an amal 627 and there's only about 15-20mm between it and the air filter mounting plate/hole into the battery compartment.

Anyone able to advise on my best options for an air filter ?

You may be able to get a pancake air filter to fit but not sure.

If you can't get a standard filter, some of the narrower pancake ones will usually fit, or you can get hold of a short length of steel or aluminium tube (you'll only need a few inches, dirt cheap on evilbay) which will fit into the end of the standard rubber tube link through the centre panel. You'll then be able to mount a small cone type filter on that, inside the "toolbox" so it will all look standard.

Thanks both for comments.

Bess, thanks for your link. Not sure how I missed that - as I went to the site. I actually have the gauze, the rubber  ring that that goes round it, the circlip....... but not the housing (that from the diagram I've seen) it fits within.    If anyone has a spare one or happens to see one at an auto jumble let me know !

Will have to take the suggestions and for the time being rig up something in the tool box area so that it looks right.

Kind Regards

Bess

yes like that. I hadn't even realised it was integral with the air filter mounting plate (obviously come off on mine under previous owners). The one shown on the link seems to have gone. So will need to carry on looking.
