[replyingto=scootnwinn]scootnwinn[/replyingto]What he said. a backfire on decel means you're running too lean.

Drill a couple 1/2" holes in your air box.Keep an eye on your plug though....  Personally Id rather have the nice smooth growl with minimal popping.. |

if its poping on decel its usually not backfireing . your idle jet is to small. backfireing is completely diferent and i wouldnt recomend it. backfireing tends to hapen with certain timing issues . not because of a lean deceleration.

[replyingto=geh3333]geh3333[/replyingto]He's 19 years old,, I remember at that age I blew alot of stuff up on purpose and by accident...dude,,your really better off running with the growl on decel as long as its running good .If you want more noise you should get a Harley. No offense bro  |

disconnecting the vaccum hose for the carburetor air cut off valve ( de-accel valve ) will cause more popping on de-accel.
Don't forget to cap off the disconnected vacuum hose and air valve fitting.
When the throttle is slammed shut at high rpm, the mixture goes lean, occasionally too lean to fire, the unburned gas & air accumulates in the muffler until the extreme high vaccum goes away as the rpm decrease and the mixture starts firing in the cylinder again. The unburned gas being dumped in the muffler can be set off the red hot header pipe or cat converter ( initually ) or later by hot exhaust gasses when it starts firing again when the high vacuum goes away as the rpm drops off.
Later carbureted cars used to have a dashpot to limit how fast the throttle closed from just off idle to idle to reduce exhaust popping and for emissions.

loud it freaked the outa ppl lol ;D ;D ;D ;D
i think more fuel would bring it back bc when it was backfireing it killed my gas
and id sacrifice again lol ;D
and the flames were a good 5-7 inches pure blue like a tunner
