Usually the air/fuel mixture screws have a brass cap on them! The only way to get to them effectively is to remove the bank of 4 carburators and drill out the brass cap and remove with a self-tapping screw.
If you have an owners manual or a service manual it will show you where they are located. What make and model and year is the bike we are talking about?

  1. The closest i can get you to the brass caps is to tell you they are on the bottom of the carburators near the float bowls. You will see a small stem sticking up that is cast aluminum and it is there that you want to drill a hole. Use a 1/8" drill bit or a 3/16" bit to drill a small hole in the caps. NOTE: THE AIR/FUEL mixture screws are right underneath the brass cap, so drill slowly as to not damage the flat blade screw under the cap!!
  2. Then once you have all the holes drilled, take the small self tapping screw and screw it in slightly so as to grab ahold of the brass cap. Then once you have all the brass caps removed, adjust the idle screws out 2 1/2 turns out.
  3. Next, i recommend buying a jet kit and installing it in the carbs as this will make the bike run better. (Your choice at this point). Around $120.00 for jet kit and $50.00 for air filter.
  4. Also, if you order a jet kit, it will have pictures and directions on how to find the pilot / (Air/Fuel mixture screws).
  5. Also when reinstalling carbs, spray WD-40 on intake boots and carbs to help them slip into place easier...
  6. Next step is to tighten all the loose bolts on the boots for airbox and the intake boots.
  • I guess the easiest thing i can tell you to do is join a forum for your peticular motorcycle and they will have directions on what to do exactly step by step.
  • Good luck and let me know if i can help u further...HDTV GURU JAY

Hi, I have a Mac-3200 and need to know where to set the 3 carb. screws at. T, low and high I don't have a manual Thank you. Z-man


Most guys adjust them 'by ear'. Warm up the saw (hopefully you can get it to start), and set the high speed by opening the screw until it sounds like it is 'burbling' at wide open throttle. DO NOT adjust until it is screaming at its highes attainable rpm !!!! If you do, the mixture will be so lean it will damage the saw under repeated heavy load. Leaving it 'burble' at WOT (wide open throttle) will ensure that proper lubrication will be available in the cut. Under load, the burble will disappear and the saw should pull strong and not overheat, damage the piston or score the cylinder wall.

Next set the low speed screw until there is no hesitation in rpm increase when the trigger is pulled. Some suggest setting the low speed first then the high speed so you may have to readjust the high speed once the low speed is done.

The idle screw should be adjusted to where the chain is NOT rotating the guide bar at idle. If it continues to move, the idle is too high.

The carburettor how to adjust the air and fuel mixture on the carburettor


Find the adjustment screws on the front of the carburetor. Then Start the engine and let it warm to normal operating.
Adjust both screws equally and find the right mixture.Bring both screws up slowly and listen until the engine purrs smoothly. Any raggedness or rattling is a sign of too lean a mixture. Keep turning until you find the sweet spot.

How do I adjust the CO and fuel/air mixture


the CO and fuel/air mixture is not adjustable on modern cars , only on carburettors . the engine management system will ensure correct fuelling, if there is a fault with this then in most cases an engine management light will illuminate on the dash board

Carburettors seem to be running too rich. Can't locate air mixture adjusters, if that's the problem.


The air mixture settings dont often change by themselves, its usually a small screw under the carb, and is sometimes blanked over with a alum plug .
as the air filter gets old it can richen the mixture even if the filter looks ok and clean.
the carbs float bowls can flood due to dirt or corrosion as will require a carb overhaul.
If the air filter or exhaust has been changed from standard, this can mean rejetting, the air screws have their main effect at idle

Hi i have an lml sensation and the plug keeps


Hey June, the correct assembly. cleaning. setting, and adjustments of the carburetor are CRITICAL....Please take the carb to a qualified professional to get it cleaned and set. Ask him which screw sets the idle speed..and you can set it when you reassemble it.. (ONLY adjust the idle speed screw!!)
IF this machine has oil injection, and its been working fine.. do not adjust it...AND .. if the oil is injected into the carb (i've seen one or two bikes with this set-up)..its working fine..the fuel/air will be taken care of when the carb is fixed! Make sure your air filter is clean!!.. and a new spark plug will help!!
