Try turning the gas off and take the fuel line off and clean it out or mayb put a screw driver in though it to clean it and then take the carb apart and clean the pilot jet and the main jet then check the carb bowl for any signs of dirt and clean it out. then put the carb back together and put the gas line back on and turn on the gas. let on for about 30 seconds to a minute then take carb apart toe c if gas is in the carb or just lay the bike on its side to see if gas comes out. and if gas does come out try kicking it about 10-15 times or mayb more (no more the 25 times.)and it should start. hope this helps

Just purchased this car for my son. The rear end vibrates at speeds over 65 MPH but runs fine at lower speeds. Had tires rotated but they are more than 50% worn.

Again, if the vibration wasn't apparent before the tire rotation, look for a broken belt in the tires, bent rim or perhaps a wheel weight has gone AWOL.

Wont start

Check the blade bolt is tight, if the starter kicks back it may have sheard the flywheel key, to check this you will have to remove the starter and flywheel.

I need to know the correct carburetor float level for a 2005 ktm 65 sx

All carburators work axcitly the same . The float level is dertermined by the amount of fuel in the float bowl . When the fuel level reaches a point in the bowl the floats rise and shut of the neddle valve until the engine can draw enough fuel out of the bowl to drop the floats so the neddle valve opens again to supply the bowl with fuel to make the engine run its fool proof . If your haveing an over flow issue where fuel is running out the tube on the sides then pull the carb and clean it you shouldn;t need any parts just a can of carb cleaner and always clean the air filter that how dirt gets in .Good luck with it

Fresh fuel? Drain the old stuff out, put fresh fuel in it, lean the bike over until fuel comes out the overflows and give it another try.

2002 hyundai accent died and wont turns over but wont start.its my sons car and he is many miles away. the mechanic at canadian tire said camshaft and plugs need replacing. i had my son check for...

If not starting U have either a fuel delivery issue or a no spark situation. Open a fuel delivery joint by the engine and turn on the ignition. If fuel squirts out the pump is fine and the hassle is with the spark. Could be bad igniter causing either no spark or a weak one.

Rear wheel freezes up (so far driver side only)

Could be rear brake locking up,cars arent used to going backwards or hand brake sticking on . Would look there first.
