Got a 95' LT50 cc 4 wheeler wasnt running when I got it, it has spark and fuel to carby but wont start. pulled carby off and cleaned it out, I pulled the starter with carby off doesnt seem to have much if any intake suction, got plenty of compression. any ideas?

SOURCE: new top end but no compression or very little

Sounds like you have the crank to cam timing incorrect.  Also you may have the valves set too tight.  Dose it pop and sputter?

SOURCE: bike wont start

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Clean the air filter. Install a new stock NGK spark plug.

Please rate this solution. Thanks!

remove all of the old fuel using a siphon bulb and hose. Put in brand new fuel and make sure the line from the tank to the carb. is flowing gas. if not clean or replace the fuel line

1ST CHECK THE PLUG IS IT DRY AND CLEAN IF ANY DOUBTS REPLACE IT.as spark plug might work good out but under pressure its a bit differant . or check the valve clearance on Exhaust'Ihad the same trouble with my Triumph 5oo years ago

DOES IT HAVE SPARK? IF IT DOES YOUR REEDS MAY BE BAD
