I'm new to live steam having purchased a Accucraft Mimi this past October. As many have lamented, I had to spend a lot of time leveling the existing pike to facilitate live steam. This season I have had more fun and run time with the improved grade. I was dismayed recently when the engine performance began to get progressively worse (even with the pressure to 80 psi). When I put the engine in reverse, I was taken aback when it took off like a jet! I then learned about inside admissions and valve timing. I read Dave Hottmann's article on LargeScale.com, but after 4 hours of tweaking the eccentrics I'm starting to wonder if I am doing something wrong. I think I've got the preliminary optimal stall points, but before I start messing with valve adjustments to equalize the 3 and 9 dead center hesitation goal, I would have a better comfort level if there were any other more indepth explainations/experiences accessable in forums or elsewhere on the web. I guess I'm looking for a "for dummies" type explaination. I have some concern that the engine runs very rough in the new (inside admission) reverse position during air testing, which isn't a problem for me. My goal is to have it run at peak efficiency in forward gear. I just don't know what new behaviors are be expected. <br /> <br />Thanks, <br />Rich F.
