Re: Stromberg 97
I recently completed some dynamometer testing on two engines. In both cases we tried to gravity feed a single Stromberg 97 carb and found we could not develop power under a heavy load. When we added a fuel pump to raise the fuel line pressure to 2.5#, the problem ceased.
On one of the engines, we also tried a pair of 48's and a pair of 94's. They were a bit more forgiving. I did not try the 94 as a single but did test a single 48 and when doing so, it had the same loss of power under heavy loading.
Hope you find your solution.
Good Day!
