Carb Fire Risk?, Need advice about carbs and air filters Options

[NickFBrown]

I'm considering a '73 1.7 that some idiot put a single carb conversion on. It would be no problem a put on dual carbs instead BUT my last 914 burned when the right air filter caught fire (backfire?). It normally never backfired but this was on a hot restart after being stuck in stopped traffic on a very hot day.

Has anyone heard of this happening with dual Webers using the typical open sided air filters? I know there must be thousands of cars with this set-up. So, am I worrying for no reason.

Sorry, but (respectfully) what's your question?

You had a 914 with carbs on it that backfired and started a fire, right? You're now asking if a backfire through a carb can start a fire?

Don't you already know the answer? Best wishes with this potential project 914!

Be careful out there everybody.

Of course I know that a backfire can start a fire. I guess my real question is why are there no better air filter housings that would keep the problem confined to burning up the filter? That is what I started looking for in the begining but no joy.
