No, not exactly. When I was trying to tune the engine with the stock carb, I got it as good as I could, then installed my glow driver to see if things improved. They did not. It made no difference at all in the way it ran. This tells me that you can't fix a carb problem with a glow plug. Just like you can't make a glow plug light by changing the carb. I'm not familiar with the MDS 1.48. I've never seen one run, and nobody I know has one. Your readings appear to be very strong for that prop.

Why the need for a replacement engine? Did you wear it out? I haven't run my 2300 in the warm weather yet, so I don't know if it will turn up more or not. I really need to get an apc 16-8 to see how well it compares to the Saito 180. That engine turns 9300-9600 on 15% nitro. I'd like to see 9300 on 10%. I'm not very far from that with the Master aiscrew Classic.
