No. The 2.0 have head vents, the 1.8's do not. Not sure about the 1.7. And I don't know what motor you even have at this point. 3 bolts intake manifolds? If so, then they are 2.0 heads and should have head vents.

You sure? My 1.8L does. I thought all 914 heads were vented. (I've thought wrong many times though)

All of the stock 1.8's heads that I've seen have not had vents. And mine on the current power plant weren't either. They are now though. (IMG:style_emoticons/default/wink.gif) (IMG:style_emoticons/default/sawzall-smiley.gif) We need a drill smiley.

The cleaner is supposed to be kept off skin, but nitrite and latex gloves simply melt away. How long do I have before the cancer sets in?


You can get solvent-resistant gloves at Home Depot.

Is "starter valve" a Weber thing? You're not talking about a "cold start valve" with FI are you (probably not since you're elbow deep into the Weber)?

Yes...a Weber thing. 99% sure it's soe kinda choke thing that I don't have in these guys. I guess the only way I'm starting this thing up in the winter is to turn on the garage heat a few hours earlier.

a couple of pumps on the throttle, start it up and nurse a slightly high idle with your foot for a minute or so. the engine should settle into an idle and you can drive off.

He maybe referring to the accelartor pumps on the carbs , should have them , check your diaphrams , look into the throats to see if the carb squirts fuel into the throats ( venturies ) when you operate the throttle arm ( s) .

Nah...and there's no "he"...it's the Haynes Weber Manual. Almost certain it's referring to the webers that have choke assemblies. The "reassembly" instructions alrerady had gone past the accelerator pumps.

Well, I tested my floats in water. No fumes, no need to protect skin, no explosions, no stink. I think the rookie is right in this one. Anyway...no bubbles. I'm betting these guys are not even hollow...anybody ever slice one in half?

QUOTE(r_towle @ Oct 8 2009, 10:51 PM) *

QUOTE(kenshapiro2002 @ Oct 8 2009, 10:44 PM) *

So...what's the reason for using gas?


QUOTE(r_towle @ Oct 8 2009, 10:26 PM) *

QUOTE(kenshapiro2002 @ Oct 8 2009, 10:18 PM) *

That's the tab I thought you meant...the end that has the split in it...that the rod presses into.

My thought is, that if you submerged the float in water, and saw it was leaking (bubbles) wouldn't you replace it?




QUOTE(SGB @ Oct 8 2009, 10:14 PM) *

You just don't want to get water into a leaky float, then have it slowly creep back into the gas in the bowl.

I'm not a vendor, I did buy fuel line and fittings and venturis from aircooled,net.

The tabs I broke are the ones that HOLD the pin that the float pivots on (two in each carb next to the needle valve), not the little flat tab on the float assembly that contacts the needle valve (the one used to set the float height).



I use gas, and yes....if you see bubbles, replace it.
I have not seen one that is bad unless its from a really crapped out carb full of water and dirt...most of the time the floats on Webers seem fine in my experience...
I still check every one.

Dunno, just seems logical

My float was at 8mm (with gasket on), instead of the 10mm it should have been. What significant behaviors, if any, might that have been causing?

Everything else looked pretty clean in this first carb, and it's going back together very nicely...no where near as confusing as I thought it would be...definitely a 3-4 on a scale of 1-10. I;m guessing that if carbs were a problem with my performance, it was more the adjustment itself, but we'll see.

And my "drop" measurement (I understand it's nowhere near as critical though), was only 25 mm. Needed to open that up to 32mm.
