SOURCE: I am trying to determine

Yes, it is the cam chain tensioner. With the engine off, just loosen the tensioner lock bolt then strongly tap a few times on the tensioner casing with a screwdriver handle. This will free up the spring loaded tensioner. Now just re=tighten the tensioner lock bolt and you're done. Please rate my answer. Thanks. tombones49_157.gif

I have a Briggs & Stratton Vanguard 16 HP motor. It idles fine and it runs OK at high RPMS. But it backfires thru the carburetor during accelerating. Any suggestions?


On some float-type carburetors, you can adjust the air-fuel mixture and engine speed at idle. Check for an idle speed screw designed to keep the throttle plate from closing completely, and an idle mixture screw that limits the flow of fuel at idle. If your carburetor contains these screws, proceed below.
  1. With the engine off, remove the air filter and air cartridge.
  2. Locate the idle mixture screw and turn it clockwise until the needle lightly touches the seat. Then, turn the screw counterclockwise 1-1/2 turns.
  3. If your carburetor has a main jet adjustment screw at the base of the float bowl, turn the screw clockwise until you feel it just touch the seat inside the emulsion tube. Then, turn the screw counterclockwise 1 to 1-1/2 turns. Replace the air cleaner assembly and start the engine for final carburetor adjustments.
  4. Run the engine for five minutes at half throttle to bring it to its operating temperature. Then, turn the idle mixture screw slowly clockwise until the engine begins to slow. Turn the screw in the opposite direction until the engine again begins to slow . Finally, turn the screw back to the midpoint.
  5. Using a tachometer to gauge engine speed , set the idle speed screw to bring the engine to 1750 RPM for aluminum-cylinder engine or 1200 RPM for engine with a cast-iron cylinder sleeve.
  6. With the engine running at idle , hold the throttle lever against the idle speed screw to bring the engine speed to "true idle." Then, repeat the idle mixture screw adjustments from Step 4 to fine-tune the mixture .

My bike runs good up to third gear then when you go to forth gear the bike struggles almost like a cylinder is miss firing in i had the engine light come on when i down shift the light gos off have yo


I believe you have a carburetor. There should be a rubber boot from the carb, to the airfilter. the boot may have come loose for the carb. and is taking in to much air.

RUNS ROUGH-BACKFIRES STARTS GOOD THEN DIES-IS IS IN NEED OF CARBURETOR ADJUSTMENT OR IS IT POSSIBLY VALVE ADJUSTMENT? THERE APPEARS TO BE NO WAY TO ADJUST CARBURETOR AIR FLOW AS OPPOSED TO OTHER...


In a 2-stroke engine, the valving is done by the mechanical relationship of the piston position in the cylinder. No adjustment is possible other than grinding the cylinder ports or changing the piston skirt shape. You need to check the fuel filter (in the tank), air filter, and muffler for plugging. Because the engine is designed to burn a small amount of oil with the fuel, the muffler tends to plug over time. Check the fuel lines for decay or other damage. The carburetor has a rubber diaphragm in the lower chamber that decays over time as well. Go to: http://www.drystacked.com for a 12 page article on Walbro brand carburetors that are typical of chain saw carburetors. Good theory and troubleshooting information. 2-stroke engines are picky about air leaks behind the carburetor. Hope some of this helps!

1981 550 suzuki one cyclinder is dead has spark and fuel and bike runs but start extremly hard seems cold blooded


Check compression of cylinders, all should be close the same. Swap spark plugs and check if problem cylinder moved. If bike sits for long periods of time then most likely it will be a plugged carburetor.

ADJUSTING THE IDLE SPEED AND MIXTURE
On some float-type carburetors, you can adjust the air-fuel mixture and engine speed at idle. Check for an idle speed screw designed to keep the throttle plate from closing completely, and an idle mixture screw that limits the flow of fuel at idle. If your carburetor contains these screws, proceed below.
  1. With the engine off, remove the air filter and air cartridge.
  2. Locate the idle mixture screw and turn it clockwise until the needle lightly touches the seat. Then, turn the screw counterclockwise 1-1/2 turns.
  3. If your carburetor has a main jet adjustment screw at the base of the float bowl, turn the screw clockwise until you feel it just touch the seat inside the emulsion tube. Then, turn the screw counterclockwise 1 to 1-1/2 turns. Replace the air cleaner assembly and start the engine for final carburetor adjustments.
  4. Run the engine for five minutes at half throttle to bring it to its operating temperature. Then, turn the idle mixture screw slowly clockwise until the engine begins to slow. Turn the screw in the opposite direction until the engine again begins to slow (image A). Finally, turn the screw back to the midpoint.
  5. Using a tachometer to gauge engine speed (image B), set the idle speed screw to bring the engine to 1750 RPM for aluminum-cylinder engine or 1200 RPM for engine with a cast-iron cylinder sleeve.
  6. With the engine running at idle (image D), hold the throttle lever against the idle speed screw to bring the engine speed to "true idle." Then, repeat the idle mixture screw adjustments from Step 4 to fine-tune the mixture (image C).
