Head gasket

Oh yes, seems I have a problem with numbers, no telling where 285 came from. I blame it on my typing teacher.
 
I (not the car) broke down.
The local LBC guru seems to believe the carbs are too rich, worst case scenario a stuck needle. I give him credit, he diagnosed this as he is blind, said the valves are fine.
In his defence, I took him for a ride when I had some tunnel knocking, said it was the leaf springs, not the u-joints, by jove he was right.
I didn't get the compression test done however, but will tweak them H2's this week.
So, does this sound like an acceptable feasible diagnosis?

I still haven't figured out how he knew the midget was red???? /ubbthreads/images/graemlins/confused.gif
 
Sure, go for it. Worse case is it just maybe something else, but hands on is always best.
 
"Black smoke"= running rich. "White smoke"= burning oil.

Adjust the carbs, use the Bentley manual proceedure and you'll be as close as necessary. Be prepared to spend some "quality time" if this is the first time you've done it, as it's a bit of a back-and-forth process. The fella who diagnosed it by ear heard the "splashy" exhaust and felt the way it runs... pro'lly smelt the rich condition too... a real "seat of the pants" kind of eval. Good ear!
 
Thanks Doc,
I'm currently watching a velocity video on such process, I have a sick day next week that coincides with the wifes first day back to school, I'll tackle it then with 10 uniterupted hours.
As Jack said, if it's something else, then something else it is and I can deal with that, but at least my carbs are tuned.
St. Louis here I come!!!!
(If I can rebuild the calipers in time!)
 
& start with the carb where the gas goes first.
 
If it's black smoke, it's running "fat" (rich). The smell should give it away too. White-white smoke would smell "sweet" and be antifreeze burning, indicating a head gasket. White-blue is oil and that'd be rings/guides/seals. Black is unburned hydrocarbons and you need to turn yourself in to the EPA as a gross polluter...

...or just tune the beast! /ubbthreads/images/graemlins/jester.gif /ubbthreads/images/graemlins/grin.gif
 
Tony, they mentioned in the video to start with that one, but didn't explain why, just curious as to why?
Thanks again.....
 
Start with Carbs? Cause they easy and fast if you have done it a hundred times.

That's why I'm setting aside a whole day! First time, wont be the last.
 
If its not set properly, the "secondary" (I say that only because it gets gas that flows through the 1st carb) would have to be retuned after you tuned the 1st one - even if you had it right the first time...because of possible changes to fuel flow.
 
Oh yea back and forth, back and forth. Kind of an intresting job though.
 
In the interest of my massive curiosity, I did a compression check and all four were 190 give or take two or three, plugs good etc. H2's here I come......
 
Excellent, lucky you.
 
Was that 190 dry or wet? What're the wet numbers?
 
I hope those WERE the wet numbers!! That's mighty high for a stock '74 Midge.
 
Barry, back in July, I did a wet and dry on my '72, and got numbers between 138 and 155 dry, and wet pressures about 12PSI higher across the board.
Bone stock, 65,000 miles.

I'm still interested in the wet numbers.
