ok last night i was driving my ford f150 straight 6 truck (1984)automatic with air
and as i pulled into a parking lot a lady got out of her car screaming that my truck was on FIRE my muffler has a hole the size of my head was shooting flames out for about 4 feet lol
what can cause this is it the carb or exahust
someone said i need a new carb then someone else said i need a new exahust
help

 

I say both, new exhaust and a tune up should fix it.
The only thing missing was some Hot Dogs

 

hahaha its too cold for hod dog here in washington state

 

The fire was a result of VERY rich exhaust (high HC emissions), which is due to the carb being out of tune or damaged (mine split the accelerator pump diaphragm & washed the rings out) &/or the catalytic converter being ruined/contaminated.

It was visible because of the hole in the muffler, probably due to a severe backfire, which probably also resulted from the rich exhaust.

I hate carbs, and the 1-bbl on that engine is among the WORST. That's why I converted my truck to EFI.

.

 

Get some insurance and let it burn................

 

running rich is not enough air and too much gas right???. i always get lean and rich confused.i must admit im ignorant when it comes to carbs.

 

so what do you suggest for a "stupid" girl who knows little about cars and truck
please explain in simple words that i can understand lol

 

New muffler, possibly a new cat converter, bout 50bucks for a carb rebuild.

Buy something new. All girls (stupid or not) understand THOSE simple words!

 

ROFLOL!!!

Indeed, tune up, carb rebuild, new muffler (if not the ehole exhaust) and possibly a new cat are all in-line.
