Back story:
genuine VM26 on a YX160 with low compression and starting to smoke, with this carb on that particular engine ran fine and hard even with low compression, no bog, fairly easy starts etc. no issues, ran it for a whole summer
!!!! I know, should have changed the rings and valves but too lazy....
details: #20 pilot, #180Main, middle clip, float height-->floats parallel with bowl bottom. Air screw 2.5 turns out.
Recent story:
So obviously rebuilding that engine this year. I have another bike but it had a POS molkt on it that worked up until now when apparently it just died. SOOOOOOO, took the genuine VM26 off of the other bike (from the bike mentioned above in the backstory) and put it on this new bike with the same engine YX160. This engine has good compression, no leaks, no smoking etc. Basically the bike runs great, about as good as the other bike but when rolling through the throttle, the mid feels ever so slightly flat, also, after heavy bumps, hills or long stretches of idle, it will bog when cracking the throttle. Not sure if this means too much gas or two little. As a note, I have the air screw out 2.75 turns vs. 2.5 turns. Seems like the further I turn it out, the less instances of bog but it's still there.
Curious to hear feedback, I'm thinking either it's float level or jetting but I really hesitate to play with jetting considering this combo worked perfectly on the previous engine and I have tried playing with jetting before and have always come back to #20pilot and #180main.
