Just another ‘HO HUMM’ day at the flight line

I mounted the Saito 120 on my latest project (Extra 300) and went out to maiden the Extra – as I was trimming the plane out the engine died – I was in a good position for a dead stick so there were no problems. I did some checks and adjustments the plane fired right up and worked fine on the ground for 3-4 minutes. So up I went again… 5 minutes later I was dead sticking another landing.
I called it a day and tore the plane apart that night – I found carbon pieces in the fuel tank, it would seem that they got blown in from the muffler and then sucked into the engine.
I cleaned out all the lines and blew out the needle valve etc, the next day… nothing worked …
Lots of testing and I finally took the carburetor off and disassembled it… yes there were chunks of carbon there too… reassembled the engine, retuned and it works – but it is now too windy to try out a questionable engine.
I went home modestly annoyed but with an undamaged AC that will fly another day…
Now I have boiled the muffler in antifreeze to remove the carbon and I installed an in line filter to the carb. – Just in case…
Life is either a daring adventure...

Re: Just another ‘HO HUMM’ day at the flight line
There are many people , that have many days , just like you have had . I have my turn also .
One time last year, after a bad landing day . I spent a few hours during the week to repair the aircraft . Got to the field early , so that I could have a little time alone with the aircraft . First the engine was hard to start , and when it did start , it was going into a very high RPM . I found the problem in a short time . I was missing a 5mm screw that was holding the carburater , the engine was leaning out . I waited for a while to see if anyone would show up . A few guys showed up , but no-one had such a small screw . I ended up going home to get it , 30KM away , got back to the field and it started to pour . While I was at the field , the spirit of the club never let me down .
Beleive it or not , I still considered it a good day ......... WHY ......... because I did not want it to be a bad day , Thats a decicion that I made at the start of the day , What ever happens ...... happens
Michel.......... P,S. ..... always use a in line filter..... I learnt the hard way too
