This engine is a challenge to get to operate satisfactorily. It’s very sensitive to wick length, placement, as well as to how it’s trimmed. After hours of frustration and e mails to service,, it appears to work but there is still need to refine my technique to get optimum performance. This is definitely for experienced hobbyists who enjoy a challenge..
Quality product and received it well before we were supposed to. Very nicely designed machine. Works great!
This engine is a wonderful piece of Engineering! Built exceptionally well and runs fabulous. Vacuum engines are mesmerizing to watch, cant help but be amazed with their simplicity. I run this engine on a variety of fuels, Alcohol 95%, Alcohol 99% as well as methyl hydrate. Runs equally well on any of them. After maybe 15 minutes total run time I take the cylinder heads off and clean the inside with Alcohol. I also use light "3 in 1" oil on all moving crankshaft parts and of course no oil inside the cylinder. I have used graphite inside the cylinder but frankly I dont see any need, runs like clockwork without the graphite. A lovely vacuum engine addition to my collection!
Exceptionally well built and runs like a champ
This engine was running minutes after I removed it from the shipping box. I must say it was also very well protected with bubble wrap around the engine and also bubble wrap protection throughout the box! It is a heavy engine, solidly built. The crankshaft turns very free and has no lateral play or movement, this engine could not be built any better. I just mounted the fuel tanks, lit the wicks and the engine was off to the races. This is my 4th vacuum engine and definitely my favourite!, runs terrific every time and has a very pleasing mechanical linkage sound as it is running.
