Re: [T3] Nasty Backfire


	I don't know if this helps or not...

	On my Beetle with dual carbs and no steering wheel lock, it's
"fun" to cut the engine power and let the engine stop while running
downhill.  Instead of using brakes heavily, you can still do engine
braking by leaving it in gear and letting the motion of the car drive the
engine as an air pump.

	When you turn the key back to "on" again, POW! goes the backfire. 
Presumably this is the ignition of unburnt gas that got sucked through the
carbs, into the engine, and out the exhaust as the car did a bunch of
engine braking with no spark... and once hot exhaust starts flowing
through again, it ignites.

	So, er, not that I know that much about carbs, and even less about
stock Type III carbs, but could there be some way you've started running
really rich, or dumping gas into the intake from the carbs after you stop?

Guessing,
-Greg
