As always guys..... As the title says.......

Any info on magneto's with a "Tacho drive" ?? And before everyone jumps in and says

"you can run a normal tacho with a convertor box"
I am not interested in doing this as I have heard alot of bad things about these   Like being over 1000rpms OUT!!!!!, Needles bouncing badly, etc etc etc

Plus I really like the idea of a PROPER mechanical tacho giving a REAL reading of whats going on out the back  
I know alot of the mechanical Tach's where built by "Jones Motorola" for the Vertex mags - I am maianly look for info on the Mag's
Does anyone have one for sale



So lets hear what you know guys

You planning to watch your tach in your rear view mirror?
I don't think magnetos were meant to use really long tach drive cables.
Mechanical tachs are for engine in front, or a stationary engine, where the drive cable is two to three feet long.

That being said... I'm sure you could always get something custom made.

There is the mechanical type (VDO I think) that run off the oil pump with a special cover and a long cable to the front. You see a few Ghias with this set up.

Hmmm thats what I thought....... the 356 runs a "mechanical" tacho of this type

I thought I'd bump this thread........

I really really want to run a mechanical tacho on my SPG motor......

I am having the tacho FULLY rebuilt/recurved etc by an Old guy that Ian knows so I can get a mechanical "Drive" fitted if needed, But I am also interested in these oil pumps......
 (not 356 but from an industrial engine!)
