That's where everyone has their shorts in a bunch over nothing. The engine has to have been at an extended idle, tuned rich on the low end, and permitted time to develop a fuel puddle for this to happen. In flight it just ain't so. Even an extended approach at low throttle presents at best an insignificant chance of killing the engine, and even then it would only happen at a rapid throttle up. Jody at Valley View has THE correct fix for the condition, but it's not something he can do for free with every engine that's been sold. Hell, he shouldn't do it for even one engine.
A part has to be manufactured and installed to cure the basic condition, anotherpart woulkd well serve general performance after the basic part was installed, and there is no way a distributor is responsible for the cost in time and labor. Nor should everyone suddenly start making calls and e-mails insisting that this part be provided to them. It's a manufacturer responsibility and should be left that way.
I am one of the people that had 2 of these engines and they both did the same thing, I have sent them back twice and still they will not run below 2100 without dying. You also say there is nothing wrong and yet the manufacture says there is. I fly off of a smooth surface and at that RPM you can't even turn the plane without it tipping over and if you lower the throttle your walking to get it because it died, AND YESSS ITS TUNED PROPERLY!!!!!!!!! I have 3 gas engine at the moment and they are all DL 50 and they run like a champ, I guess i have them tuned wrong too.
I do agree that Jody should not be doing the fix's but if they want to sell these engines sombody better do something, besides tell us to run the idle up.
Anyway not my problem anymore because I have sent them back for the final time and getting my money back.
