Hey, I recognize this one! I actually own 25% of this beauty (I think it's the SW corner in the picture). The test stand is a real gem. The only mod we made was to mount the tank farther back to allow a little more working room when we were testing the larger engines. Having the "test stand" mounted permanently on the board which is then clamped to the top of a roll-around table saw is the ultimate in convenience. It puts the engine at an ideal height for adjusting, etc. and having the ability to move it into the shade/sun/under the garage walkway as appropriate makes it usable in almost any weather. When we're finished, we can stand the board and test stand in a corner of the garage until we need it again. (It also allows each of the 4 "investors" to take it home with them if they so desire.) So far, it has worked out great! The actual test stand is first-rate all the way. You will not regret your purchase...
