    Thanks for your reply but battery is charged with a new fuse

    The most likley problem now is the ignition. Either timing or a failed CDI (ignition box or coil).Does it fire at all? or even turn over?

Hi
I have been working on my carb today,the pipe from the bottom of the carb should just run down by the bottom of the swinging arm,there should be another pipe from the pipe on the left side of the carb just above the fuel intake which also runs down to the swinging arm and connect to nothing.
Cheers

Pay special attention to the parts in red. DO NOT mix parts from the front carb with parts from the back carb. When removing adjuster screws and jets, count the number of turns to remove them, write it down, and replace with the same number of turns.

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx

Go to this site and you can download a free PDF service manual.
www.carlsalter.com/motorcycle-manuals.asp Most all of the manuals are in English but some are not. There is no way to be sure without doing the download. You can always delete it if in a foreign language.

Take the carburetor apart again, remove the main and idle jets and idle mix screw, plus the float and needle valve. The main jet holds an 'emulsion tube' in--look inside where the slide valve moves, you should see a short brass tube projecting out of the bottom. Carefully push down on that tube with a plastic rod or wooden dowel, it should drop out the hole where the main jet was. Chances are that the tube is dirty and needs to be cleaned--look carefully at the series of small holes drilled into the sides of the tube. These small holes deliver air which is mixed into the fuel passed through the main jet. That air comes from a small hole just inside the intake side of the carburetor. The long needle that sticks out of the slide bottom controls low to mid-range speed fuel-mixture. Check that the 'C' clip on the top end of the needle is in the center groove and that the retainer spring is pressed down the 'C' clip. Now soak the whole carburetor with spray cleaner, then blow out all passages with compressed air. Don't soak the rubber-tipped needle valve from under the float. On reassembly, set the idle mix screw 1-1/2 to 2 turns CCW from CW stop. Adjust for best idle after you get it running and warmed up. I hope this long winded explanation helps!

Replace fuel filter after cleaning tank thouroughly, to clean tank remove fuel line at carb. Drain all fuel then leave line loose until you flush tank with carb. Cleaner then blow out tank with compressed air. Now install new fuel filter and check your fuel can for trash and water better yet just add fresh fuel.

My 1974 Yamaha 250 Enduro wont start I have cleaned and redone the carb. I have changed the coil pack and spark plug. Any suggestions will help Im not a mechanic by any means so not sure where to start...


you need good compression ( at least 90 psi , kicking it with the throttle open) , good crankshaft seals for sucking the fuel/air into the botton end, proper point gap and timing set for spark ( spark should be big and fat,if not the source coil is weak,, this is a flywheel magnito ignition and it needs no battery to fire the plug) if you clean the carb, make sure you also clean the choke pickup tube or it wont choke. also make sure you have the slide installed in the right direction ( not backwards and the idle is not set too high at first...compression/****-good spark at the right time-proper fuel/air ratio and it will run

Wont run without choke being pulled out 1/4 .


INFO:
-Remove Carb and clean, you have a high speed fuel port clogged.

NOTE:
This would also be a good time to replace your fuel lines, Take photos before you start.

RECOMENDATIONS:
-Drain all fuel from the Saws fuel tank.
-Remove and REPLACE with a NEW spark plug.
-Remove and RELPACE with a NEW Air filter.
-With spark plug and air filter removed and fuel drained pull the starting cord many times 12 or so to ensure there is no fuel in the chamber and also check for a spark at the plug.
-RE-MIX WITH NEW FUEL your 2 cycle oil to the correct ratio in a clean fuel can. it is OK to dump some in the Saws fuel tank slosh around and dump out in an approved container for disposal.
-Hold off on putting back on the air filter until you have had it running.

Hope this Tip Helps.

2002 Hyosung GV250 running problems


Time for carb cleaning , blow the jets with compressed air,check the float level.
Check the spark plug and replace if neccessary.
Check the air filter too, and if you don't have an 'inline' filter for your fuel line,install one.
Basically yr bike's engine needs a tune up...check the valve clearance too!
Hope this helps!

Your carbeurator is crudded up. Get a can of aerosol carbeurator cleaner at any auto parts store. Remove the air filter and spray two squirts of cleaner into the air intake. Start the engine and keep it running by squirting more carb. cleaner into the air intake. WIth a little patience you will clean your carb. and solve your problem.
