yes the speedo works, don't know how accurate, but it works fine, no jumps between miles, so i guess works just fine

for the the 43 i guess there related to my car alarm, I was planning to change cuz was given me some problems, the cables was cut out by mistake kindasad.gif

for the 71 I'm really lost where could be the problem.

don't know if the 71 can be affected by the fact the hose that goes from Air filter to the engine was loose.
