Bent needles can cause horrible throttle response. Start by installing a new needle that way you know its not the problem. If your carbs have rubber diaphrams make sure they arent ripped.

Hope you have kept notes on all the carb setting changes.
Did the problem start when the exhaust was modified? If not it may not be a carb problem.
Does the problem change if the engine is cold or hot?
Does it make any difference with the choke on?
Is the air filter new and clean, new plug, valve clearances adjusted, new oil.
I know I havent answered the question, but hopfully gives you a few more things to check

The chain saw runs okay until i start to cut wood on higher revs then it cuts ouy


Does it run O.K. with high revs. with no load, but dies when you start to cut (load) ? If that is the case your carb. needs to be adjusted and that is difficult to put into words. Without knowing what make of carb you have because they can change from year to year, and also depends on the model. Without knowing make of carb I suggest you try to turn the L (low) and H (high) needles in (clockwise) until they are lightly seated so you don't damage the needle or seat. Now turn them both out (counterclockwise) one turn as a start. Start your saw to let it warm up now rev it up it should not hesitate or run rough while reving up. If it does turn low needle out 1/4 turn or more if needed until it does not hesitate. (turning any needle out will let in more gas turning in less gas) If you get this far good idling and reving up, now adjust high needle the same way. With high needle you can also try turning it in. keep on adjusting needles in or out in small increments until it runs right. If you cannot get it running right after all this, you probably need a carb overhaul, just a cleaning or carb kit if diaphrams are stiff or damaged. I hope this helps you. Please forgive grammar errors. Let me know how you made out.

My zxr400 will not rev and carbs are clean


Are you sure there clean? did you dissasemble yourself?
I had similar issue and i 1. removed carbs 2. drained float bowls 3. removed main jets
I soaked main jets in carb cleaner, then blew all passageways with carb spray, then sprayed carb spray through all passageways in the carbs, i checked all rubber diaphragms for cracks especially the float bowl ones, my main problem was old varnished , gel like fuel traces which had built up from bike being idle over winter.

Once i completed this i reassembled and the bike idled steady and also revved cleanly to 15k revs, you might also want to check your fuel filter as it can effect flow rates if clogged with old varnished fuel

Aprilia af1 125 sintesi, carb settings, what are the standard jets etc in the carb, also how do i set up the carb to run right, have a k&n filter fitted, bike has flat spot/bogging down between 5000 to...


Hi and welcome to FixYa,

Jet size would depend which carb is installed, a Dellorto 34mm?

Initially, check the sparkplug tip colors. If very light brown to almost whitish, then lean mix; too much air, too little gas. Try raising the needle if if has notches and moving the e-clip. If fixed, use small thin washers. The basic idea is to make the needle rise early on throttle movement.

If an aftermarket open breather air filter is installed, then it would be causing the lean mix, too much air. Restrict the filter by adding temporarily upholstery foam to experiment at which thickness the flatspot would disappear.

Good luck and thank you for asking FixYa. Happy Holidays.

You changed the back pressure in the exhaust and that is what causing your problem either put the washer back in or have the carb properly jetted

check carbs and throttle, clean float chamber. Jets are factory fixed so try second hand carbs rather than mess with these

Honda CR125 Motocross bike throttle delay


ALWAYS have a fire extinguisher on hand when working on carburetors.
Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Now pull the top cap off the throat of the carb and remove the large slide. There will be a long needle in the center of the slide. Remove the needle and then move the clip at the top on the needle down one notch. Two notches may be required but start with one notch. Put it all back together and try it out. Moving the clip downward richens the low end fuel mix.

A “very helpful” rating for this answer? Thanks!
