So I bought a new one way after experiencing obvious problems... Followed directions to a “t”, now the engine turns, starter works, brand new battery, the 660 just wont start... I have checked the obvious, brand new battery, brand new spark plug... could it be fuel? I let the quad sit for about 3 months between my last ride, now I want to go over Labor Day, so I got the one way replaced, just cannot get her to run... Advise? Things I may have overlooked?

Has the engine ran after you put the one way in?

Try using starting fluid - if it tries to start, then your carbs need to be cleaned thoroughly.

Petcock: Fuel valve between the tank and carb. Turn it OFF and idle the engine till it dies when you're going to leave the quad sitting for more than a few days - this drains the carb's float bowls and eliminates fuel evaporation from leaving crap in the carbs, plugging them up.

Remove seat, pull airbox lid off (you DO know where this is, don't you?), spray starting fluid onto the air cleaner, try to start bike.

Have you checked for spark yet? If there's no spark, unplug the regulator and see if it comes back. Of course, if there's no spark, don't bother trying starting fluid.

Read addition to my last post regarding draining the carbs for future... remove and thoroughly clean carbs for now (assuming you have spark).

There is spark, I will try the starting fluid trick, and also attempt to clean the carbs, it’s just getting to them that looks like it’s going to be an issue... any good tricks? or just pull the tank? or is there enough room if I pull the airbox lid off?

the hardest part of cleaning the carbs is putting them back on the rubber boots... and make sure all the clamps are nice and tight when you put everthing back together..

Alright, So I have some good news, and some bad... My carbs are immaculate. Good. (cleaned anyway with compressed air and rubbing alcohol) bad news, i overlooked a bad choke cable. The plastic connection between the cable and carb was literally hanging out of the carb obviously not engaging the choke when i tried... ordered a new one, should be here wednesday... and hopefully be riding wheelies by thursday! Could that be the reason?

By immaculate, did you remove each jet and clean it? Run some speaker wire through the jet passages (thank you QM) to make sure they are clear. They make seem to be clear otherwise, but this way is a way to ensure this. And yes, your choke cable could have been part of the issue as well.

No, I didn’t bother with all that, mostly because I could not figure out how to remove the throttle cable from the housing but removed both bowls and they looked brand new... blew air through with compressor and also my mouth, as gross as it was. One carb was way easier to blow through than the other, but I believe by design... Once I saw that the choke cable was shot and hanging from the carb I figured that was it, but since I was that far decided to look at the bowls in case. Crossing my fingers, that is the problem. If not, I’m F’ed

You just need to take the covers off your bowls again in order to remove the jets, they come out with a flathead screwdriver. Better you do it now rather than have to take them off again after you put everything back together. Just do one at a time. You don't need to completely remove the carb from the throttle cable in order to clean your jets.

If you don't remove each jet and clean them separately (using copper wire strands + spray cleaner on tiny central passage of the pilot jets), you will be doing it all again soon - believe me.
