Weber Carb to Manifold Petrol leaks.

[Russell]

Calling all weber/dellorto'd cars and owners. What carb to manifold gaskets do you use? Nylex plates with loose rubber O-rings, or Misab bonded O-ring plates?

I'm using the Nylex plates with thackeray washers for the DCOE40s on my Spit, and when I turn the car off, I get the excess petrol dripping from between the carb and the manifold, onto the chassis - right next to the exhaust! I've replaced the plates and washers, but it's still happening. Now I also assume that when running it's sucking air in through this gap too.

Am I being too impatient about getting the tension on the washers right? I don't think the rings have moved as I held them in with a small blob of grease when fitting the carbs.

Is there some extra sealant I can use?

Would I be better swapping to Misab plates with the rubber spacers?

Any advice would be much appreciated.

thanks,

Russell.

I use Misab one piece, Thackeray Washers at the bottom of the carbs, rubber doughnut things and cup washers at the top.

Are you using a fuel regulator?

You may have too much pressure?

I use a Malpassi Regulator.

Hi Léon,

No, I don't have regulator yet, I bought one last week but haven't got round to fitting it yet. The new Misab gaskets are on order, so I sense a bit of re-plumbing at the weekend.
