Model A highway speed.

[Rakkasan]

First, let me apologize for my ignorance. I never thought I had any problems with my Model A except when a cop friend of mine told me that if I planned to drive it on the highway I needed to be able to travel at least 45 mph.

So one day I pulled out onto the highway and got near 45 before it backfired loudly and stalled out. This happens every time I get around 40 mph. I did notice that the engine sounds like it's taching at a high rate.

So just how fast should a model A run?
