Very cool Mike. This is one of the most detailed writeups I've seen. Good job, and great idea.

Now all you need is a k&n filter for the stock air cleaner

Think I should of used the pizza dish.....instead of the pot lid.....:lol::lol:
A little heavier guage
But..... once it's riveted to the bottom of the air cleaner and the hole is cut.... bolted to the Weber.....and then the whole unit mounted to the valve cover.
Should be more than..... stable enough.....i think:blink:

Don't mind at all. In fact, it kinda bugs me when guys start 5 different threads on exactly the same thing....makes it a lot harder to search for the info later.

yep...but I like the $4 price of the paper one more :) I did put a Amsoil equivalent in my wife's 521. ...hhmm...I might actually have another one on the shelf too.

Well, since you're riveting it, you can redo it if it's not stable enough. I used the side of a computer case on the first one....it wobbled....that's why this one got the 16ga :) You could use some angle or bend a couple of strips of sheet metal to make angle and rivet those across, just outside the mounting holes...might make it more rigid without having to completely redo it.

Thinking I could have cardboard in there.....:lol:
Being mounted to the valve cover and all.
The pot lid....in theory.....should 'somewhat' counter the wobble.:D

Decided to make another plate for the base of the air cleaner.
No wobble now..............:D
Riveted that on.
Fits rather well.....just have to clean everything up....then rattle can it:cool:
Oh......and also mount the Weber and remove some emissions from engine.
EIA tubes from the EM will be hooked up....but plugged.
Not sure yet about the ATC....it's the vacuum motor at the end of the air cleaner.
Good for cold starts......engine will run leaner......but????
Eliminate?

That came out sweet!


As for the ATC...it also helps keep the temp in the air cleaner high enough to keep the carb from icing up. If you were worried about air flow, you wouldn't be running a stock air cleaner :) If it was a show truck more than a driver, I'd ditch it, but it's a driver....keep it :)

Actually...wasn't thinking about the air flow from the stock air cleaner.
Just couldn't afford to buy a Weber AC right now:(
But....I was out today....in another 720.
I know the ATC is not functioning properly because I plugged all (most) of the vacuum (emission) hoses on the stock Hitachi
The truck has been underpowered lately...(winter).....then all of a sudden it would start missing, big time.
No power.
Black smoke is belching out...turn it off.....pop the the hood....ice on the carbs base plate.
Wait a minute......flashes right up.....good to go.
Happened twice so far.
ATC....?

On the base.....I'm thinking the hot water running through the manifold should stop that from happening.....did someone bypass it?

Well ....if some one did....it was me.:lol:
Other than the emissions..(hoses).....nothing has been touched.
Thinking that the length of the snorkel on the air cleaner drawing cold air in would contribute to the ice.????
Relative to being heated by the EM
Not knowing......just a guess.:blink:

Black smoke is too much gas....so maybe the choke is sticking closed?

If the ATC were working, the length of the snorkel wouldn't matter as much.

Check the emissions hoses....I wouldn't be surprised if you have a water valve controlled by them that would heat the intake.

Initially I thought it might be the accelerator pump.....or choke
But.....It was wide open.....no leaks around carb....couldn't check the sight (dot) glass to confirm flooding.
Carb might be partially NFG.
Might have to put that Weber and air cleaner on....help make it through it's last winter;)

Has anyone used this Weber adapter on an L16 powered 510? Did it the air cleaner hit the hood?

I had the idea to do this about a year ago, then I join up here a couple of days ago and see that many others have beat me to it!

Ah well, at least now I know it works!

 

Thanks for the write up!
