markpulling Posted April 17, 2011 Share Posted April 17, 2011 Hi all,the guy I fly with has had his pap ros 125 for 2 years and his motor is always a little smokey ,I asked him what his fuel mix is and he said 40:1 ,I fly a pap top80 which is 50:1 ,and hardly smokes at all ,we both use the same castrol tts oil,on the pap website it does say 40:1 for the ros 125 ,but why ? parajet are all 50:1 ,was just wondering what ratio other pap 125 owners use ..thanks in advance Quote Link to comment Share on other sites More sharing options...
simon101 Posted April 17, 2011 Share Posted April 17, 2011 Hi I've always stuck to the manual with 40-1 on mine, but saying that it has just blown a hole through the piston... Quote Link to comment Share on other sites More sharing options...
garyfreefly Posted April 17, 2011 Share Posted April 17, 2011 40-1 ....with fully synthetic for me....piston replaced with the new one at around 60hrs....(as a precaution)...although it did not look like there was anything wrong with the old one ?? now got around 120hrs on it and it sounds as sweet as...should I say that !!!
