I have an MDS 2.18 with a 20x6 prop on a rascal 110 . The motor is mounted inverted and my problem is getting a reliable idle . I broke the motor in on 10% nitro . Every time I think I have it adjusted just right for transition, it won't idle. another problem is after it shuts off, re-starting is impossible without removing the glow plug, drying it off, reinserting it, and then it will start by hand the 1st or 2nd try. ANY help with these problems would greatly be appreciated. I won't fly 'til I can figure this out.
