Title: Any info on magneto's with a "Tacho drive" ????? Post by: Lee.C on March 02, 2013, 16:22:18 pm 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 :) Title: Re: Any info on magneto's with a "Tacho drive" ?????

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. Title: Re: Any info on magneto's with a "Tacho drive" ?????

You see a few Ghias with this set up.

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!) . |
