My mini quad bike wont make a spark when i try to start it up.we had it start up the day before.

Try turning the carb set screw all the way in and back out 1 1/4 turns. If you need more... do it in 1/4 turn increments.

most likely carb setting. Try turning the carb set screw all the way in and back out 1 1/4 of a turn. then adjust by 1/4 of a turn to fine tune it.

My 49cc 2 stroke pull start scooter wont turn over

your carb might need a clean.a clogged jet inside might be the problem.make sure you have free flowing gas to the carb

my quad wont start at all it turns over but not getting spark whats wrong with it ??

Maybe re-check the gap between the coil and the flywheel? x2 business cards is a good gap for those.

i have i 50cc ATV quad and we have done every think to it and it still won't start but the fuel isn't going to the spark plug any one know what to do. ?

Need more info before any one can help. Start with the most basic things first e.g. has it got fuel? is the fuel switch on? is it getting spark? and so on.

To check the spark put the spark plug in the cap and rest the tip of the spark plug on the head of the engine and crank it over. You should see a strong spark.
(Remember doing this creates electricity so don't touch the tip)

if it has a kill switch make sure it is on, check that you are getting spark at the plug and have the right fuel in the motor.
Remove the air filter from the carbi and squirt some 2 stroke fuel directly into the throat of the carbi and try to start it.
hope this helps
