Gantry crane in place with chain fall made working on this 7 HP Economy engine possible; in fact, we picked it up in order to access the gas tank. The tank was deteriorated, and we ill be making a new one. Here we see instructor Doug Kimball who co-taught the class with Russ Welch. The two taught our previous three consecutive Saturdays class; this class was a one day eight hour class. Both these guys have a wealth of knowledge about these early gas engines having been long time collectors and gas engine presenters at Maine Antique Power Association meets.
We did not succeed in starting this engine, as we ran out of time. Our original class was three consecutive Saturdays, but this time round we couldn't find students who could forfeit this time so we went with a one day class. And, of course, we couldn't accomplish as much in the eight hours we had this time round. A number of problems were revealed. In re-inserting the cylinder the top ring broke; on this particular cylinder there were pins on rings two and three but not on number one. Nevertheless we thought that we could achieve enough compression if we re-arranged the intact rings we had positioning them at the top and middle of the cylinder. We re-inserted the cylinder and thought we would give it a go. There were other issues with the new igniter seal that we had replaced but nevertheless leaked and lost compression. We also had issues with a build up of red paint that effected our governor system. The plan is to go back and remove that material and make it move freely.
