After driving the IIA for approx 15-20min, car just feels like it run's out of gas, and it dies. Once it cools down it fires right back up and runs for another 10min or so and does it again. I am still gathering the facts on this, but the first thing I want to rule out is vapor lock, as to get it started this last time I poured some fuel into the carb and I could hear it bubbling, I guess from the heat of the exhaust manifold which is right under the intake. I am new the Series IIA's but not new to Carb's, as I used to work in old carburated 911's, so I am learning the idiosyncrasies of the IIA...
So when it died I did the following:
1) Disconnected fuel line at carb and manually pumped fuel to rule out blockage.
2) Cranked car and directed fuel into plastic container to verify FP working.
3) Checked for spark at each plug.
4) Unscrewed plug on bottom of carb fuel inlet and watch fuel come out while starting.
5) Pulled carb top off to validate fuel in the carb bowl.
Bottom line, I am getting spark and fuel (to a degree)...
Any thoughts on going to an elect pump like a facet and bypassing the mech pump, as I am really not sure that the mech pump is pumping the correct amount of volume of fuel as well....
Thoughts?
