I need your help with a 912UL
Went flying, all was good, the flight was uneventful, landed, had a brew, and off I went again.
This time just after take-off, the engine lost power, rev counter dropped to about 4300rmp from 5000rmp, cut the throttle and landed, engine still ticking over taxied to the end of the strip where I carried out a full engine run, no problems there, did a high speed run down the runway, no problems, so turned around and gave it another try… same thing happened, loss of power on take-off.
Taxied back to the hangar, checked the fuel, in fact I put new stuff in. Checked the fuel filter and carb bowls for debris… nothing found.
Put new plugs in it…
Started the engine, even had the lads tilt her skyward so simulate take off angle of attack… no problems found.
Taxied off and, began the take-off phase… this time now engine power loss. Flew for about half hour, landed. Had a cuppa, then about an hour later, carried out the pre-flight checks as I fancied another quick flight before heading off home, this time whist in the clime out, another power loss, this time not enough runway to land, so I did a wide turn and landed back on the runway, put the her away in the hangar …a little confused.
I've stripped down the carbs, cleaned them out, found a few O rings that looked suspect so have ordered two rebuild kits.
However, I really don’t think that would cause the engine to lose power…
So guys, what do you think, anybody got any ideas what to do next
Looking forward to your replies
