Smell? Sorry for Another Post...

[Girl In Big Truck]

Sorry for an additional post so soon, Hate to to have to make another so soon.

So, I have an Edelbrock 1406 600 CFM Carb installed, running good, and on the fine tuning stages.

I have the fast idle and and in idle set as low as I can get it.

Running fairing smooth, but the exhaust smell, though faint, is weird. Like something burning, but not gas.

I have the two pins adjusted to low fuel pretty far, and wondering if that is what is the problem. I am trying to get a really good balance, and as little fuel consumption as possible. But wondering if this carburetor is just a fuel eater and there is nothing I can do about it, thus have to keep the pins set higher?

It's running well, just the smell I am wondering about. If I adjust the fast idle and pins higher, I get better acceleration, more gas smell, and pump, but I am looking for smooth, not a hot rod. I am potentially going to be hauling up to three tons back there, not race Hondas... (though I could probably)

Am I making any sense? Gas versus other burning smell from exhaust? (faint, not over powering)

1974 Ford F-350 360 V8 5.9L Engine (fyi if needed)

The pins do not make it run more efficient, as that will be determined by the engine. They also only affect idle, the jets inside the venturi control the flow off idle. You need to adjust the screws to have the best idle quality, which is a fine balance between too much and too little fuel supplied. Too little can cause a lean condition, which can potentially lead to engine damage or just poor performance.

Sometimes when something hasn't been run for a while it has a "smell" about it.

Oils burning off the pipes, rust inside the pipes etc. Usually this calms down and goes away.

New Exhaust??

 

[Fellro]

Charlie is very much correct, a vehicle that hasn't been run for a while will smell a bit while things get settled. If you put on new exhaust components, they will also commonly give off a smell.

Disco... That makes sense. New exhaust, all those new parts, a new carb. Was trying to figure out what it smelled like, but couldn't figure it out.. not plastic, not gas, not rubber, just a weird stinky exhaust smell. New stuff smells bad when hot I guess...

Going good since last post, just doing hairline adjustments right now when I feel something is off. Still a slight timing issues, but may be another future several days of reworking (timing chain, valves, piston rings, ... ), but just slightly and randomly off. Saw a 1960's sedan today all couped up, it had that same slight offness to the firing, and I was the probably the only one around that noticed it...

Predictions on next fiascoes: brakes, bearings, clutch, heads, and the usual rust.....

And I just just went through my pilot/escort vehicle certification class. Hell yes, I plan on using this truck for it...

Don't apologize for posts..that's what the Forum is all about!

Cool on the pilot truck!!

Duncan's right, we're all here to help each other on the ol FTF, that's what the forum is for. No need to apologize for your post. I've even had problems with my 78 F-150 Ranger Lariat, and I have found different solutions for my problems, and I've also helped others with my wealth of Ford truck knowledge, that's what we're .0

I like to see the old trucks working. I would just love to see a dent as a pilot truck!
