Default RE: tuning ys 63 engine

rlipsett... I have two YS 63's and two YS 110's... I have not flown with the
110's yet... and I have the samething happen to my 63's.. Not sure if it's
just a trate of the way these engines run or not adjusted right. They tend
to be finicky at times, But for now I love the power/size and throttle
response. They tend to be effected by heat... I believe that the YS's go
from a normal(carb) fuel feed at idle, and "sort" of an injection feed above
idle to top end.. and I'm not sure if this is part of the loading problem at
about 1/4 throttle setting????
I have not had YS's for long, so I'm still learning the do's and don'ts... And
for now:-) I love them.... I have just tuned per the instructions on YS's web
site.. And it works pretty good... But it does run a little rougher when it gets
hotter... And it does here in AZ:-(... Anyway I've never had a deadstick..
Well I've had a few fuel out dead sticks...
