Does your fuel line still run up around the front of the engine and above the exhaust manifold? Re-routing it up over the valve cover will keep it cooler. I wonder if the CA summer gas is detrimental to the accelerator pump if its not kept wet or allowed to dry out?
I've only been there driving chase for the Baja and Mexican 1000 races. Loreto is a friendly town in a beautiful part of the peninsula. Plenty to do and a minimum of ill behaved drunken tourist malarky.
