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!
Looks nice but that's where the fun ends. Will not run.
Nice desk weight
It seems from the reviews this engine either works or it doesn't. In my case it never did run!. Big disappointment
