It has the wrong spark plugs. I ordered this engine for the small 1/4 x32 spark plugs and have been in touch with Ryan at legend hobby and have heard any more about a remedy. Still Waiting
Received engine with missing parts.
Missing muffler bolts and gaskets, engine standoffs, spark plugs.
Nice engine, excellent service
I purchased my first Stinger, a 40 twin, and installed it inside the cowl on my Goldberg Yak 54 which is 77″ wingspan and quite a pig by todays standards. At 14 lbs, this is a heavy plane compared to most. This engine pulls it with authority and sounds great! Always hand starts and I broke it in while flying. I have one DLE 20 and it runs good, but lost all compression after 12 flights. I installed a Bowman ring and the compression has come back. But why should I have to do that with any engine? I’m now a Stinger fan, and will buy my next gasser here.
Super Fast Shipping and got exactly what I ordered!
