I hope your Magnum 40 works out better than my .46 did. I bought that thing 15 years ago to save $20 and never could get it to run properly. I exhausted my ingenuity then, came back 12 years later with 2 engineering degrees and still couldn't get it to run well. Frustrated every expert at the field one day with it.
I'm chalking my trouble up to a faulty/porous casting or a cracked something or another that I cannot see. I spent $114 on an OS 46 AX and have not looked back.
Best of luck, but sometimes they are just bad.

I got my engine with a package of other stuff (Trainer, radio, New OS 91 four stroke, field box, starter, 12 V, and a 60% built Norseman) for $200 CDN from a guy getting out of the hobby. I plan to use the trainer and Magnum engine as a backup incase I kill my trainer (which has an awesome OS .46 FX). The Magnum seemed to be running pretty well the last time I had it up and running, and based on the feed back from the guy I got it from, it was a pretty reliable motor for him. I think a new plug and some work tuning and it should be just fine for what I want it for. I may end up moving it into my trainer if I get the courage up to make my GP Corsair a flyer this season.
