Get a compression tester to see if she has plenty of compression or take spark plug out ,put your finger over plug hole and turn engine over. you should feel a pressure forcing your finger away.

Raptor 80 started turns but does not engage motor

sounds like the starter clutch is bad. the rollers get worn or the sprag gear gets worn so it will not grab and start the motor. check that out. you will have to take the engine side cover off to see it.

Cut out wont start

all cars , gas (otto cycle)
it only takes 3 things to run.
good engine. (compression test time number of cylinders) WOT.
good spark. (test it)
good fuel mix. (spark tips wet or dry)

if the engine is good, and the spark is hot and timed right.
try test fuel if engine is not flooded, (is it?)

try test fuel, if tool less or no money for a real mechanic.

it sounds like you sucked in water through the air box take the front of and see if its wet if it is then you will need to clean the carb as the bowl will be full of water once you have done that remove the spark plug and give it a clean too with luck that should have cured the problem if it hasnt then maybe you have broken a piston ring when you sucked in the water

hope this helps

Hi, have you checked the compression, usually when they turn faster than normal (motor that is) than it is not a good sign, if compression is ok, maybe your valves are sticking which would cause it to turn faster, try changing to a good quality oil!!!
