I have a 1970 240 that is in a E100 and everything is OE. I have a couple questions about what is normal and I'm hoping someone here can help.
- ~7 or so years ago (<1500 miles), I put a Autolite rebuilt Carter YF on. It started leaking very small amounts of fuel from the throttle plate onto the manifold. Basically, the leak was enough to stain the intake manifold, directly below the shaft. Here are some pictures of the carb in the area of the leak (replacing the carb again, now). Is this leak normal for this type of carb?
- When I replaced the carb 7 years ago, I noticed some rock-hard carbon at the base of the inside of intake manifold. This is where the exhaust system pre-heats the fuel/air mix in an OE configuration. I had the inside of the manifold blasted ~200 miles ago and see the carbon coming back now that I'm doing the carb swap. Is this normal or am I running too rich?
