ok i have a 1990 blaster, the bike has been setting for like a month 1/2 maybe two, well i changed out the gas, put a brand new spark plug, too the carb off and clleaned it out really well, made sure to get all of the bad gas out, so i am going to start it and it wont start, but after bout 20 kicks it starts, but only for like 5 seconds and has a high idel, so i shut it off, wtf, so tomarow after work i am gonna get some starting fluid or some ether, so i can start this bitch, will starting fluid or ether hurt my bike

 

First you gotta figure out the reason for the high idle speed. Something may have been put together wrong, or the idle speed screw is too high, or the cable is binding, or the slide is being held open.
Starting fluid is hard on all motors, and if you get carried away, it can actually cause some big damage. Youre best bet, is to get someone to pull it, and compression start it. Thats the easiest on the motor and easiest on you.
Just have the key on, in 4th gear, clutch in, have someone start pulling,with a lawn tractor or truck or another quad( you only need to go about 7 mph), and once youre moving ,slowly let out the clutch. Youll hear it spinning over, and it wont take long and itll run on its own.
Where is the air screw set? should be about 2 turns out from seated.

 

its has a rebuilt engine that has less than 20 hours on it, plus it converted to a twist throttle(pro motion)cause the old on just bunrt to
s h i t on my fmf fatty pipe, and when i put the new pro motion twist throttle on, the ugly box on the carb, this kit elimates it, and the it moves really nice, no sangs , nice and smooth

 

yeah anykind of ether will harm the engine and will make it run wild till it burns up, ether will burn the top of your piston not to mention blow the head gasket and blow it up if you give a nice amount. don't use it, ether was mainly meant for use on diesels and maybe a tiny spray into the air cleaner of a car, it's not meant for small engines, take hondabuster's advice and get someone to pull you up the road.
