I can vouch for this. I had a 65 Corvair Corsa Convertible with a
dual-carb set up (Replaced the original 4 1-barrel carbs). These carbs
had foam air filters, and the crankcase vented into one of the air
filters. Needless to say the filter was soaked in oil. One day the car
backfired, and the filter was engulfed in flames. To add insult to
injury, the spare tire was located in the engine compartment, and rested
on this carb. The flame burned though the tire, which proceeded to blow
more air into the flames, feeding them higher and higher. All in all, a
good show for about five minutes. When it ended, I started it up and
drove it home (all 5 blocks).
Brit content. My 71 TR-6 had been my daily driver for several years, and
never left me stranded until one day as I rounded a corner, it just
died. No juice at all. Odometer says...71,000.00 Coincidence? Or just
Lucas. Neither, bad battery (and probably my fourth alternator in 2 years).
