I'm building a racing lawn mower but I need a pulley that is at least 5 inches in diameter and has a hole of 1 inch in the center so that the engine can connect to it. If it helps the lawn mower is a Murray wide body riding lawn mower with a 14.5 hp engine. Where do I buy this pulley at?

Answer
Stuff like that can usually be ordered from a farm implement dealer.

How can I hook a tachometer onto a riding lawn mower?

Mike

I recently built a racing lawn mower and I removed the governor so I can get some more speed out of it but I need to install a tachometer so I dont blow the engine. Can anyone help me out? How would the tachometer hook up to the engine?
i know the idle RPM at about 1/3 throttle so i can probably figure out what size tachometer i need.
heh Charley thats funny but the blades have been removed ;) sorry

Answer
The tach is normally tied to the ignition coil, I believe on the NEGATIVE side, but you'll need to confirm this. It may depend on the tach itself. But usually it is the coil ground side it attaches to.
