Hi guys, Well I have been following the instructions to a Tee on breaking in myMagnum .70 manualfound on this link:media.hobbypeople.net/manual/210945.pdf. I've got my 45 minutes of run time starting from very rich on the top end to just rich now. I've got it at about 2 turns out. Top RPM right now is 9750 but a bit jumpy due to the newness. Top end feels right so far and I'm not ready to max it out yet. The bottom end is another story. I can only get my idle down to 4500 or so before it just quits, no sputtering or coughing, itjust stops.This is hardly an "idle". The low speed needle is 4 turns IN from the OUTposition as the manual states. I have tried to open it and close it from this position both directions an 1/8 of a turn at a time (as written) but only straying about 1/4 turn away from 4 turns each way. I'm not sure right now what to do. It does seem to transition well from my 5000 to 9700rpms well. Does my high speed needle being rich still effect the Idle to 5000rpm range? What is a standard magnum, high end and low end needle valve turn position? I would assume 2 on the high end is a bit rich still. Do I need to adjust the low end a bunch more? If so which way? And then should I pull the cover and check my valve clearance? My fuel is the Sig 10% nitro 25% castor mix since the manual wanted at least 18% oil content for break-in.I've got roughly 1/4 of a gallon of fuel through this engine and it never has idled for more than a few seconds below4500rpm.It is sideways in a GP 40 Corsiar Kit. I think that's all the answers to the questions you might have! Thanks for the help!</p>
