Weber rebuild kit for w108

[cnm]

I plan to have my carburetor rebuilt on my w108 1968 280s. It currently has weber dual carbs installed by the previous owner. I havent seen much info on the forum regarding rebuilding weber carbs. My mechanic said he could do it with approx. 4-5 hours of labor with me supplying the rebuild kit. Does that sound about right? I will probably just have the work done by my mechanic. However, I was interested if anyone had much experience/success with this project? I doubt I will attempt a DIY rebuild but want to look into it. Also, is this the right kit for the rebuild:

32/36 DGV DGAV DGEV Rebuild Kit

Thanks

It depends which Webers your car has installed.

That looks like a kit for a progressive carb, which may be the type of the one carb (or two? I assume you have two carbs installed) that you have. 4-5 hours seems like you're paying for at least an hour, maybe two, of OJT on that job.

They are fairly simple to rebuild, and if you match the settings turn for turn, you'll get very close on the new one, for a start up starting point at least. Use proper-sized screwdrivers and don't nick the mating surfaces or venturis...

Good luck!

Thanks! The car does have dual webers. I searched, but not sure how to tell if the carbs are progressive. Glad to hear they are fairly simple to rebuild. The rebuild kit does not have that many parts, so I was hoping/thinking that might be the case. Maybe I will but the rebuild kit and give it a try. Now I just need to find the right kit ...

Progressive carbs have one venturi larger than the other. The engine relies on the smaller one at low/er revs, and the larger one kicks in at high/er revs.

The designation would also be a fraction, vs a single number. 32/36 are the Venturi sizes, vs say a 40IDF which has two venturis of equal (40) size.

Typical rebuild operation goes like: disassemble, clean, blow out, clean, blow out, damn where did that jet just blow off too??!! Them set float level (depending on if the float was changed), and reassemble. Seems simplistic, but if jets and orifices are clean, and gaskets seal, you are well on your way. Crud and deposits are your enemy.

On the side of the carb, there will be a cast-in number. Sometimes you can just take a piece of paper and push it up against the casting to get the numbers off it if they are obscured. They are typically on the flat between the venturis, on the acc.jet housing, or the side of the fuel bowl.

Good luck!

Here's the company producing the kit your car is likely using. Looks to be a 32/36 DGEV.

Thanks. I found the shop ticket for the Weber replacements installed by the PO in 1984. Not much information on there other than he paid nearly a grand in 1984 for the parts and labor. However, I believe you are correct; from what I read the weber replacement would have been 32/36 dgev. The carbs were also removed and cleaned in April by the previous owner for $225. Hopefully, they will not be too tough to get clean this time around. I think I may purchase two of the kits above and give it a shot.

I rebuilt the dual Webers on my '67 Alfa Duetto about 30 years ago when I was a dumbass kid and it worked out fine, so go for it.
