Keep on with your irony. Actually when you buy a MOrgan tune or whatever else you are just admitting (to certain extent of course, and every case is different) your laziness.
Well, I reject your insult as bull#$%*e. My time is worth something. And, I have no shortage of meaningful things to do with by life. I'm not shy about making tools for expedience, and I HAVE made screwdrivers, FYI. In particular, a right angle one for carb adjustment. Partly because I could make it with materials already on hand, and partly because I didn't want to wait a week and spend $100 on a tool I could make in under 30 minutes.
I paid $50 for my gauge set in 1975. Still works today. Calibration is a non-issue. A five way gang manifold is all you need, available at nearly any aquarium supply. Hook all four to the same vacuum source and tweak (if necessary) till they all read the same. The check and adjust takes a couple minutes, at most. I actually did contemplate making my own manometer set back in 75. But, when I realized the raw materials were going to be at least a third of the finished tool cost, I bought them instead, and went riding the latter half of the day, on my smooth running bike. I STILL don't feel a bit guilty about buying that tool. Jeez, back then, it was $30 to have the shop sync it, plus the wait in the queuing period to have it done. With that rationale, I really only paid $20 for the tool!
So far, Dave has $44.50 in his set up and he still hasn't got the right gauge type. He's over half way to $80 with his art project, not counting what his time is worth. It's his time to spend as he wants. And, if he's happy doing it, fine with me, though kinda amusing. And, he'll benefit from a learning experience. But, buying tools instead of making them is not done simply for laziness reasons.
Think I'll head out to the couch.
Cheers,
