Hi People
I've just realised that this project started in 2009! :o So anyway, I'd just like to thank everyone who over the years has read the thread, encouraged me, made me laugh, answered emails etc and helped out in so many ways both practically, with knowledge and parts that has made this project possible.

Thanks everyone wherever you are... :D :thumbsup: :D :thumbsup:

Have you pulled the string on it yet?
Mercs are like women, no 2 are exactly alike. That's what testing is about. In general it is safer to test motors and props than women!

Pulled it over without fuel...that's noisy enough! It's all mounted and rigged on Colliwobble, just need to add water, fuel and ear plugs.

Normal water flush muffs won't fit due to the low water pick up, I'm going to see if I can rig something up in the next few days and get some fire in her.

Also waiting to see if it will be ok to run it at Ivy Lake

Link to short video of motor run at Ivy Lake:-

http://youtu.be/_CUpQfJ7aGs

At this point only the bottom two cylinders were firing (patting top pipes to check) and the bulk of the noise is away from the camera. It was chuffing loud from the other side. :D

Very nice work by Healey 75 :thumbsup:

The camera is a lot more modern than the operator, who appears to have missed the moment all four pots ran, probably filled his bag due to the shock of the noise :shock: :oops:
