mike: i know i was going above 70 because the pointer was firmly pegged there, and i was accelerating. as for revs i was in ... 5th gear doing around 5000? something like that. as for the hot cold thing, ill try putting it in the fridge but is that something that id only need to do once? wont after i reconnect it it just have the same problem another day.

and speedo heads? thats the face right?

as for the less than a hundred bucks rasta, that does make me feel alot better. that wouldve been a paycheck and then some

but i have to say, i was a little disheartened that while the car has good pickup, better than i initially thought, it most likely wont do over 120mph. but at least it looks and sounds good while its getting there right


as for the refrigeration plant maybe ill just put an icebox in the back and throw ice cubes at the speedo every now and then to keep it cool

Hey Tinman, had a similar problem with mine which I just figured out after pulling a spare to pieces and observing what was happening while spinning it with a drill.

The speedo needle is on a shaft connected to a rotating drum with no other connection except the return spring. This shaft is only supported at two points, a nylon bearing at the base and a bronze one below the dial face. In my case the molly grease that I liberally applied to the drive cable after thoroughly cleaning it a year ago had worked its way up the cable, through the fitting and bush on the rear and built up an excess inside the speedo mechanism. A blob of thick grease was causing resistance on the drum and limit the speed, causing it to get stuck for a while.

I cleaned of as much grease as possible before using a can of degreaser and compressed air to remove it all. Then sprayed over it and the bearings with CRC (WD40, RP7 etc) to lube it all. I am sure a good clean and lube will fix it.

Oh yea, you have to dismantle it but there is info here and a link to pelican if you do a search.
