We just had a new development with our RV-10 engine. It has 1,350 hrs SMOH and just had a thorough condition inspection. 3 plugs were replaced and all intake and oil drain tube hoses were replaced.
When the engine is cold, it starts fine, but when we advance the throttle it quits unless we get the throttle past a certain point and then it runs fine. In other words, it idles just fine and it runs fine above, say, 1,500-1,700 rpm, but in between it won't stay running. Once it warms up a little, like a couple of minutes, then it runs fine and keeps running fine.
It doesn't seem to make any difference if it has the boost pump on or not, so I don't think it is a mechanical pump failure.
Any thoughts?
