Well I ended up Belt sanding it with good results. Its nice and straight now. Now all I need is some washers with .125 of an inch step to be able to snug it down. I was thinking on using filed washers but I have to remove half the thickness of the washer to get a step of that size. Would using a washer that thin be a no no? its about .155

Wanted to ask a question, is it possible for the fuel level to be to low? I check the level of the fuel in the bowls and the fuel sits at about 30mm -32mm down from the top off the jet tower, Is this ok, to low, not enough? I got the floats set at 15.5mm

Should be 27mm from the edge of the carb body. Not sure how that relates to the "top jet tower".

Ok so it has to be at 27mm from the side of the carb body, no more no less. I think the jet tower might be a little higher than the sides so ill use the carb body for reference.

Thought I would update this, got the car up and running and its driving pretty good. the tuning is in question though as I have lean pops when cruzing or part throttle in one carb, so i pulled the plugs to see what they looked like and 1-4 turned out to be just about right. 5 & 6 is another story, #5 was rich and #6 was lean?, All the linkages are dead on and opening at the same time so im not sure if its jetting or what. Other than that cars runs pretty hard.

Maybe float levels are out in the 3rd carb?

I had that prob too, one carb was leaner than the rest, and in the end the float level in that carb was 3mm out. Once it was fixed the plug colours evened out.

I'm sure the process of checking Dell floats would be similar to Webers: http://www.webcon.co.uk/Downloads/DCOE%20float%20height%20setting.pdf

ok I will check the level on that carb, btw could float level cause one cylinder to be rich and the other lean? Just thought it was odd since it was like that on just one carb.

If it's only one plug that looks lean, I'd be more tempted to suspect an air leak in the manifold. Give your manifold to head bolts a quick visual check? One of my friends had this same issue and when he looked, one of the nuts was finger tight

...and at the carb to manifold join, what are you using? Are they are those big o-ring type gaskets?

Found out the problem was the air bypass valve was open leaning it out at idle..

Ok so I'm extremely frustrated, I took my car to a Z specialist, He was recommended to me for tuning my triples, $250 later Im still having issues, it coughs misses and backfires at low end. the only time it runs ok is half to full throttle. I was told this is normal for triples to do sometimes? After taking it to the place to get tuned Im still in the same situation I started... no new jets, still runs ruff and is pissing me off.

I even started to mess with it myself and actually got it to run better, But I only have a syncrometer so I can only adjust flow... I don't suppose there is anybody near the 90638 area that could give me a hand is there?

Are there ANY Weber techs or guys who know their way around 40DCOE's in Washington State? I'm not rich but could do some trade work, buy ya lunch, something.

It's hard to get her to idle below 1100 and there's a flat spot on light throttle. It also lags at heavy throttle. Installing an electric fuel pump today to try and feed it better at higher RPM's but think the issue is elsewhere.

Where should my timing be?

Stock L24, 142,000 miles on her with stack of service records, E12-80 ignition, stock cam, 3-into-2 header with 2.5" exhaust.

170 Air Gap

120 Main

choke? 150 and 85 F9?

Anyone?

Call me if you'd like.

Thanks in advance. Heading to the garage.
