The link posted was apparently for a photo and I can't get it to come up but anyway...

Be careful - you will likely need one suitable for a 2-cycle engine as the stock or any dual fire ignition fires every revolution which will double the reading on a tach designed for a 4-cycle engine. If you're using a module that is single fire, then any automotive version should work.

OK, I stripped the link down to the item number and found it... that will work, but you will need to "half" the RPM reading since it doesn't have a switch for 2/4-cycle. That is fine for testing and my explaination was in case you were going for a mounted-going down the road type tach
