Hi,
I am from the Netherlands so sorry for my bad english.
i just bought a 1941 ford in america. The owner said it ran perfectly.
I think he and I have a different view on that.
The engine idles well. When I accelerate slowly, the engine also runs reasonably well. when I kick the gas I sometimes get a backfire or the engine throttles. It seems like the mixes are not right. or that he gets too much gasoline.
I've already turned the air nozzles and no response.
Below is a video. It is not very easy to hear.
If it is not good enough I can make another movie.
(the rattling is the license plate holder)
