I have 4 engines on gas/glow now. all my engines seem to have more power then they did when they was on just gas. I just converted my 35cc from ei to gas/glow. When it was on ei I was able to get 8400 rpms. on gas/glow I get 8550. That is with a 18x8 prop. I not saying that you are wrong. I am just saying that I am getting more rpms with gas/glow then I am with ei. I have not ran a engine with a mag in a long time to know what I am getting.
