Mark,- I am not an expert by any means but I agree on the ice theory.- I also ha ve a picture of the accel plug fix.- I would plug that if you have not al ready.- The following info came from Dennis a few years ago. See attached.- Item #10 is a plug (11 mm I believe) and under the plug is the acceleration pump jet.- The jet has a slot in it just like a slotted screw.- Use a straight blade screwdriver to remove.- Plug it and reinstall.

Hello Guys Any idea why I lost power and had to make a forced landing ,because whe n crossing midfield for landing, the motor lost power when I throttled back. It never totally died and it regained power once on the ground after a few min utes and then it powered up and ran just fine? It has some Les Crowder mods on it, and I am not sure if those mods change th e normal operations of the mp14. I would ask Les Crowder if he were still with us. I have been asking ar ound and have had some great advice from some very nice Yak people. Just not sure if I am safe. I have been flying a Mooney and a V-Tail, this is so different. Now I am afraid to fly until I feel like I have found the answer. It remind s me of a carb ice situation. Who around the North Texas area would the right person to pay to go through the motor and check things out for me?

I'm slightly confused now. We're removing a plug to uncover the jet below it. Your last sentence says 'plug it and reinstall' , do you mean to remove the jet, plug it ( the jet ) somehow, then reinstall the plugged jet and cover it with the first plug? Is this process done on the Huosai engine too ? thanks..

David, << We're removing a plug to uncover the jet below it.>>- Yes, #10 on the diagram is the plug (11mm) t hat you pull to get to the jet. The jet unscrews, comes out, has a little hole in it.- You plug that some how..(weld, JB, etc.).- Then reinsert the jet and reinstall the 11mm plug .- My engine ran much better after the mod with no noted lag in acceleration.
