RE: MDS 40 wont start
Hi,
I think you may have discovered the cure for dead stick episodes if you can't start it. MDS = Multiple Dead Sticks.
Seriously if you work on the process of elimination. Change one thing at a time. If you have fuel, compression and a functioning glow plug it must at least fire. Check for seals/leaks and that it isn' too rich!
I have actually seen the things run in QM 500 pylon racers...........but I wouldn't own one.
Cheers,
Colin
