Re: Early S-W fuel pumps

Owen, I hadn't thought about that potential for overwhelming the model 51 carb, but it is a concern. And if you don't have an inertia shut-off in case of an accident, it can continue to pump fuel. Given those two potential hazards, I may go ahead and pop for the new 'Then and Now' pump. I just wonder who has used one and whether they have had good results.
When I bought my car, it was equipped with an air cleaner like the one on the standard eight you have pictured. It also had all the pieces of the heat baffle but they weren't installed. I'm thinking they might be removed in warmer weather for more efficient engine breathing.

Also, have you ever pulled the head from one of these
engines. A PAC technical advisor told me that one way to do it was to loosen the nuts on the head studs and then start the engine. I loosened them all about 3/4 of a turn and tried to start the engine. It wouldn't start even though it was getting fuel, air and spark. It did pop once through the exhaust manifold. I have never removed the head from an L head engine with studs. How can I get it loose without damaging it? Any ideas would be appreciated.
Thanks! Allen
