SOURCE: Hi I have owned a

Briggs has used several different carbs over the years. It sounds like time to clean the interior of the carb. If your carb has a float bowl, remove the bowl and use spray carb cleaner to clean the inside of the carb. Spray into every little hole you can find. Be sure not to get the cleaner on the primer bulb if your carb has one. If that and a new spark plug does not fix the problem, purchase a carb kit and install it.

SOURCE: Cleaning the Carb - Suzuki gz125

Looking at that bike. Seat off, tank off ,side covers etc.Turn off fuel remove fuel line, loosen motor side and air filter side pipe clamps. then remove carby from bike Unscrew plunger on top disconnect throttle cable from plunger

Most *** Carby's are the same I use any bike book or Manuel to gather info on how to disassemble and assemble.

Carby's are sensitive things if you are not sure on how to inspect and clean properly take it to a pro.

SOURCE: where is the adjuster screw for the carburettor ?

most carbs are sealed with a lead plug. Slight adjustments between carbs in the way of a star wheel knob. Carbs should be sync'd

My tiller will run with choke on but soon as i shut choke off it dies. How do i solve this problem.
First make sure the fuel filter is clean. Check the carburettor is attached tightly to the engine. The passage ways and jets in the carburettor may be gummed up. Dismantle the carburettor while ensuring that you don't damage any gaskets. Spray carburettor cleaner into the orifices and then if you have a compressed air gun, use it to blow out the carburettor.

My srm3800 runs but when itry to use it it seems to cut off like not geting fuel it idle go but it will cut off aftet I give it gas
Check there are no kinks in fuel line.
Make sure that the air filter isn't blocked.
Check the throttle cable is operating the throttle plate in the carburettor ok.
Ensure chain isn't too tight.
The carburettor should be a tight fit on the air inlet manifold.
It's possible that some of the jets could be blocked in the carburettor. You can try and clean these with compressed air but ensure you remove any seals gaskets, springs on the diaphragm pump , primer bulb etc as they can be damaged by the pressure.
If the the choke normally disengages when the throttle trigger is squeezed, check this is working ok.

If you remove the air filter you should see the choke butterfly valve on the air intake to the carburettor.
The choke lever should be connected to the axle of this valve on the outside of the carburettor.

How to set the linkages and adjust a carburettor on a Honda HRU 195 mower
Turn the engine off, Put the throttle
lever to the HIGH position. Loosen the
pinch bolt nut on the governor arm a
turn or two; just enough that the arm will
move on its shaft.

With one hand, move the governor
arm so that the throttle plate of the
carburettor is wide open. With your other
hand, use smallish pliers that's
why there is a flat on the shaft to turn
the shaft in the same direction. Hold
everything in that position and tighten
the pinch bolt.


You've just taken all the slack out of the governor linkage.

Recheck the choke, idle and maximum RPM
and you've done all the adjusting
you can do.

How and where do you adjust the synch on 1986 gsxr
I can help with this.
On the earliest models they had slide type carburettors. This is to say that the slides were actuated by the throttle cable acting on a linkage that physically lifts the slides in the carburettors. This type of carburettor has its balance(syncronization) adjusters under the caps on top of the carburettors.(the cap isn't round & has 3 screws in it)
Number three carburettor is fixed & dosn't get adjusted.

You'll have to put the bike next to a bench & attatch a long piece of fuel hose from the tank to the fuel hose on the carburettors.You can join the two pipes together using a short piece of hose that snuggly fits on the outside or inside of the two hoses. You can also join them with a suitable shirt piece of metal pipe,or what is called here in Australia a P3 barb.These are available from tool suppliers that supply air compressor hoses & fittings.
(I made a remote tank from an old lawnmower petrol tank,a long piece of hose & mounted it on a tall stand.Under it I have a tray with all my different adaptors in it.)

You adjust number 2 cylinder to the same vacume reading as number 3 cylinder first.
Now adjust number 1 cylinder to the same vacume reading as number 2 cylinder.
Next adjust number 4 cylinder to the same vacume reading as number 3 cylinder.
Recheck that they are all the same & your done.
The adjusters are of the screw & locknut(8mm)type.
You can struggle with an 8 mm ring spanner & a flat bladed screwdriver,buy an adjusting tool(genuine, or non-genuine from a bike shop) or make one.

To make one you weld a bar onto the side(at the top)of an 8mm extended quarter inch drive socket.Then find a long small screwdriver that will fit down the hole.

After you make each adjustment,stop the engine & open the throttle wide open & release a couple of times.(This seats the slide).After diong this re-start the engine & re-check your adjustment.
I place a fan blowing on the engine to help control the engine temperature as the adjustment can be a bit of a fiddle.

I prefer to use mercuary type vacume guages as they dont go out of calibration.

If you are using dial type guages check that they are all reading the same by checking them all one by one on the same cylinder.
Some Suzukis' have a pipe (covered with a black rubber stopper) at the top of each carburettor(at the front) & others have an allen screw on the cylinder in front of the carburettor manifold rubber.
If yours has the allen screw you will also need adaptors that screw into the hole once the allen screw is removed.

If you bike has diaphram type carburettors on it(you'll be able to recognise this by the top caps of the carburettors being black & roundish in shape & held in place by 4 screws), the adjusting screws are between each carburettor & are the spring loaded type.
The adjusters are located in-between each pair of carburettors visable from the top.
These are easier to adjust as there is no lock nut to struggle with & all you need to turn the adjusting screws is a long (flat or phillips)screwdriver.
Again, balance the center two first,then the left pair then the right pair.

This procedure is applicable to all in line 4 cylinder motorcycles (even most fuel injected ones.
