I was pretty pleased tody after I cranked up the old 6.2. I charged up the battery and connected it to check my glow plugs with a test light. Only one of them showed good. Well, I wanted to see if it would still run before I drop a load on new plugs so I checked the engine oil, gave it a little shot of ether and wham! she started right up.Mind you, this thing has been sitting in a field with the hood half-way open for a year and a half. Anyway, I've regained motivation to stick it into my 72. Based on some previous posts I should be able to run 40" tires with 3.73 gears and not do to bad, mileage-wise. What do y'all think?
