Hello All
We have a 1912 touring with a recently rebuilt engine and transmission. It was converted to a Model A crankshaft, with a high flow intake and a new NH carb. The problem is the engine does not perform as though we think it should. The throttle is responsive until opened up half way...(running on the road)...after that there is nothing more. When observed under the hood the butterfly appears to open all the way when the lever is pulled all the way down. In comparing this car with another one we have a 25 touring which to the best of my knowledge has never been opened, the 12 is marginally faster but not much.....like I say there is hardly any difference....lastly the engine is balanced as well......It does not run hot, however it is occasinally difficult to start when cold.......This was not a shadetree rebuild it was in fact a rebuild by one of the most well respected rebuilders in the industry.....Any thoughts?? How should a T with a A crank operate?
