Where is the VM hose connected on this engine? I'm guessing that someone connected it to some sort of vacuum port on the carb, just because this was all they had, and this is giving the VM a completely wrong signal. The VM needs straight manifold vacuum, which means that it needs to be connected to a port somewhere down on the actual manifold. In the meantime, you probably need to be thinking about getting a type 3 engine in there so it can get the cooling it needs. Even a beetle engine WITH tin won't last long here; without tin it's hard to imagine what the lifetime might be, but it can't be long. If you post your approx location, there may be someone here who can help you find an appropriate engine. Did you get the old FI parts when you bought the car? That would be the best deal for you. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
