my bug farts

Check your spark plugs. That's the most common place to look for that....also, you can make a compression test, check how is the mixture being compressed.

exhaust valves too tight and partially open for the combustion cycle? valve seat slipping in from over-heating? points on the fritz and she fired with the intake valve open up into the carb?

Exhaust leak, draws in fresh air on deceleration and combusts in the silencer.

Dear Agony Ant, :-)

Maybe you let rip, and the highly combustible gasses were ignited when they got close to the hot engine. Do you still have hair?

On the other hand - you don't sound like the "old" ANT that used to be around here... Were you decellerating at the time? An exhaust leak will cause some loud pops when you let your foot off the gas sometimes.

Just like I was feeding the tank with frijoles! ;) I don't know the technical term for that sound, so I'll call it "fart". Last evening while driving the exhaust made an explosion sound so loud I thought the engine blew up, but after a first inspection everything was fine. Why does this happen? is it too bad?

Hehehe, I get that question from time to time, and your guess is right, I'm not the old ANT, I'm a newbie with a farting exhaust. Anyway I was thinking of changing the current exhaust, too noisy.

Sounds like a fun toy to me..............Wind 'er up just before you go under a bridge and let it decellerat with the tranny engaged................make sure you do this when there's lots of cars around you so they cn all pull over and clean their pants out.......................or check their tires for blowouts.

What fun you can have with an afterfiring engine...............Sounds like you have a nice little exhaust leak to me too.

We used to do this on the old 56 Chevy V8 wagon when we were kids. We'd turn off the ignition in gear on a coast and build up a charge of raw gas in the exhaust, then switch'er back on when the lookout man called "fire" - usually beside some old lady walking down the road carrying a coupla bags of groceries - hahahahahaha.

Had a real ball till dad asked one day how the f.... the muffler got blown out along it's seam, and stopped all allowances till somebody confessed.

I had a VW with a 3" exhaust - it used to "pop" and blow small flames from the exhaust on over-run... I once got 1.5 metres of flames from it going down a hill with the ignition off and my foot flat down on the gas pedal - the mixture ignited in the hot exhaust and Viola! The guy in the Volvo behind me slowed down really fast... then I turned the key back on... !!BANG!! and off I went :-)

I had an 85 Astro Van (carburated) that would backfire when once in a while when you let off the gas. One time I was on the entrance ramp to the interstate, and it backfired at the time that I was passing a well worn looking guy walking with a large backpack on his back. The guy must have thought someone was shooting a gun, because he dove over the guardrail and hit the dirt.

Be especially cool if a highway patrol was sitting under the same bridge with a radar trap (window open) and you were a lane or two over so he/she wouldn't think it was you.... might think it was a gunshot. (course, that would be very cruel IRL... they have a hard enough job... but it is fun to THINK about)
