YS110 Props

Some of the 140 Sport's have this problem I talked to Richard  Vorano at YS 
and he said to send it in or to remove the throttle barrel and  drill out the 
hole in the barrel on the low end needle end to exactly 1/8" diam.  it is about 
3/32" diam from the factory. Remove the needle before drilling then  
reinstall the needle and open it 2 1/4 turns to start with. We did this on five  of 
the Sports, Problem Solved. You will have to readjust the main needle  and the 
low end to fine tune it. You may want to check with Richard to see if  this 
could be the problem with the YS-110 also if you remove the throttle  barrel it 
is removed and reinstalled in the left to right direction while  looking at the 
engine from the top front, if you go the wrong direction to  remove and 
install it you could damage the TB seal.
