Dannyp. I am not ignoring you or your advice.
We are under the belief that what we have are dual EMPI 34 ICTs. We believe that these are Chinese Weber knockoffs and not Solexes. I've reread the installation page that Allen gave me and it doesn't refer to the type of carb make they knocked off or any reference to pressure psi (which might give us a useful clue.)
Can anyone tell me definitively from the photos I enclosed earlier whether this is a Weber or Solex? Do these two carbs look remarkably the same? FWIW, I will say that the needle valve was metal to metal - no rubber. My mechanic is adamant that this is Weber. The rebuild kit was for a Weber.
We've ordered a Spanish made Weber replacement. At least then we'll know what brand we have. We are at our wits end with the inconsistent and dramatic flow of fuel into the right carb after the engine is turned off - sometimes. We've had to change the plugs twice in as many days as they carbon up. If started the engine quickly starts to run on only 2 cylinders.
We think that the best solution is to start with new carbs.
Thanks,
Marshall
