85 klt 110 break's up when you get on throttle

[threewheely]

Well finally got around to wrenching on this again. I cleaned the gas tank out, put a new filter in line, Got to the carb again. Cleaned it washed it ran wire through it, then blew it out with air. Moved the clip all the way down to start. Will only start if you hold the throttle open a little, but plug color is good after test. But I will move clip up, one at a time. It does seem to have a tough time idling now. Once I start it set idle, then ride ten minute's idle want's to drop have to raise idle. Might be the needle is to high. wait to see after raising the needle then go from there. However when running it does run better now. It break's up a little, but not much. What is that sensor under the magneto, it has a single wire running to it.?? If it was a car it would be a crank sensor. I have never seen one of these before. Still have no way to check jet size's when I tore down the carb, there are no marking's on any of the jet's, I guess that's cheap after market part's.

ok take the jet out

take it to true value hardware store or an industrial hardware supply store.

ask to see the number drill bits and the metric drill bits.


take the blunt end of the bit into the hole.

find the one that fits the tightest.

post the drill number and i can likely tell you what jet size it is.

i also need to know if the jet is round or hexagonal.

one clip on the needle is small, in your case it might simply be better to ride it again as is then immediately raise clip all the way if it gets better than try the middle. if it gets worse than you need to change either the jet or the needle jet.

set the idle when it is warm not just right after you start it.

what is your outdoor temp when first starting?

how much choke are you using?

a general rule is


75 degrees or higher should need 1/3 choke.

60 - 75 around 2/3.

below 60 full choke.

requiring the throttle to be open a hair is not a problem.

if you need full choke at 75 or hotter and your air/fuel mix screw is prooerly adjusted your pilot is too small.

if it starts with 2/3 choke or less when it is 60 or lower outside your pilot might be a bit too big.
