Hi all ....

I have an Irvine .40 in my trainer, that up till now has run pretty well. I have put 3 gallons of fuel through it so far. I have two problems ...

1st is hard starting, after priming the engine by opening the throttle and turning the prop over 15 times, it is still quite an effort to get her to fire up. I have a known good glow plug and plenty of juice in my starter.

2nd is an event that happened this morning. At full throttle, I noticed at first that the engine was surging. Full rpms then less then full ... you know the drill. I flew the thing, and when I was practicing a touch and go, at full throttle for take off it bogged down to idle and died. It would start back up and then die out as soon as I advanced the throttle.

I tried adjusting the mixture ... no success, then checked all of my fuel lines and fuel filter. After I put everything back together it worked fine.

Hmmm ... I don't think I solved anything, and am wondering if you guys have any clues as to what could be wrong.

Thanks in advance.

Bo
