Pok! vs. backfire

Possibly intake valves adjusted too tight or leaking. Check valve clearance and do a compression test afterwards.

Do not, ever, under any circumstances, ask me for advice on relationships.

Noted. Uh, this due to . . . twisted tastes? Failed experiments? Remarkably poor choices? Stunningly unattractive demeanor?

Let's just say that there's a trail of smoking wrecks behind me :) Amazingly enough one of them is making a comeback, dunno how that could be. ;)

Best of luck to you!

Where is the combustion happening? Exhaust kind of thing?

Burp. A good description of the sound. Completely unlike the startling "bang!" of the ain't-got-no-spark backfire. Which I would guess results from the whole darn exhaust system filling with a nice gas-air mixture then igniting.

Once it's warm -- after a few blocks -- no more burping. Is there a technical name for that burp?

In just a few thousand miles I will be performing -- yes, me, the guy that said that he would never get involved with anything under the hood of a car -- my very first valve adjustment. Picture Niles Frasier working on a car. But I have the video, I have the feeler gauges, I have Muir and Bentley. Inge will be standing by with a soft cloth to mop my fevered brow and kiss my bruised knuckles. I also have 50% certainty that I'll end up with an engine that runs backwards or something equally alarming.

Not only that, but yer oilin' down the track!

Sounds like you may be running a little lean. Is the engine really hot after you drive on the freeway? When my car was running lean, it would "pok" when I started it, and when it was cold. Check your carb jet for obsructions like dirt and gunk.

"But THAT trick never works!"

New carbs. How hot is "really hot"? I don't have temp gauge or calibrated fingers.

Hi Mike,

Yup, you do have calibrated fingers. Reach in and take a poke at the dip stick. The measurements are Hot to the Touch/Too Hot to Touch. If it's the latter, the car is overheating, and let go before you burn your fingers.

Couldn't be simpler. Thanks!

Well, the accepted way to tell if your engine is too hot, is to take out the dipstick after a freeway run, and try to hold it. If you can manage to hold it, passing it back and forth between hands, then you're fine. On the other hand, if the dipstick is TOO hot to even pull out, and you're like "yow!! too hot!" then you're engine is running hot. You can smell it too...VW engines always smell hot, but shouldn't smell like they're burning up!

If your carbs are new, they may be jetted a little lean. But I th>

Okay, finally got around to finger-testing the engine heat. The dipstick is Pretty Darn Hot. Hotter than I would like to handle. Let's call it a 3-second test, any longer and I have to take my poor little fingers off the dipstick.

Isn't one real clue to fuel mixture to take out a spark plug and see what color it is? I seem to remember that from my youth. Muir, probably, goes into that. Let's take a look. Hmmm... "tan to brown." Does that pretty much cover fuel mixture diagnostics?

The car may be running warm, but if it's overheating, you'll smell it. Remember a bus engine has to work harder to begin with, and I don't know how much stuff you're hauling around and how fast, what hills you climb, etc.

Tan to brown--all 4 of 'em, right?--would imply that the fuel mixture is being burnt ok, but I'm not sure what if anything it says about running on the warm side.
