I have 2 Marquette Model 1000 Commercial Engine Analyzers. Just the thing for your garage or man cave. In the '60's, this was the thing that your local, top of the line mechanic used to set your points, timing, rpm and tell him everything else he needed to know to make your engine run right. In the upper right corner is a dial that shows the tune-up specs for particular manufacturer's model, year and engine. There is a crank next to that dial that you move to find those specs. Both have timing lights and all the leads. We can discuss shipping but local pickup is best for me. The one with the black lower case has all the lights working and the tach moves when the unit is powered up. Asking $400 obo. On the all red unit with the Marquette logos, the left side gauge lights work. Asking $300 obo.
