I have just had my Model A restored. The car starts immediately and runs very smoothly once it has warmed up. However, I found on its initial trip out on the road that it ran well on flat roads, but had very little power on hills. It feels as though the spark is retarded, although the spark advance is in the down position. It does not back fire or stall. It just lacks power. Any guidance you can provide will be greatly appreciated.
