1996 xplorer wont start
hello,
tinkering with a 96 xplorer 400. have compression and spark.
will run with fuel dumped in the carb. took carb apart and cleaned out pretty good.
will sputter once in a while, but will not start. has brand new gas in the tank. bike mixes the fuel and oil on its own.
was wondering the correct settings for mixture screw.
also was curious about the choke. do you leave it out or just pump it a couple times. it is similar to the yamaha fuel enrichment choke they use. a metal rod attached to the cable.
do you adjust the idle screw by sight or by where the bike idles at? since I dont have it idling, was unsure where to start.
thanks for any help.

What compression reading do you have?Plus not a good idea to premix and use the injector both. Too much oil could be causing problems. Plus a lot of times just cleaning a carb doesn't work as it may need a carb kit. Around 2 turns out on the air screw on average. It's not as sensitive as a four stroke carb fuel mixture screw. Choke is just a brass plug that opens up the fuel circuit when you pull the choke lever.It's called a plunger,but you just open the choke lever. This is not a push/primer type choke.

Got my carb kit. installed everything as per the video.
I only got it to sputter twice, didnt fully start. When I let go of the throttle, the sputter stopped. Also, I am guessing I should leave the throttle adjustment all the way out so it is no used and I adjust that when I get it running.
I have tried the air mixture every which way from 1/4 to 3 turns out. Fluttered the throttle with no success, only twice a sputter.
My main needle was a little corroded. There was a set of grooves on the top, I picked the second from the bottom. This is what was original. Should I remove the throttle and see if I have any different results?
I am unsure if I should get a new main also. One was not included in the kit.
Thanks for any help.

Low end on compression on the 400 engine. Average on a good bore is around 135-145psi. Has to have a good top and bottom end compression(seals) to atomize the fuel/air/oil mixture properly to run. Crank seals are what a lot of people over look on 2 strokes also.Only way to test the seals is by a leak down test,but as cheap as they are I'd replace them. It's a little work,have to pull the drive clutch and flywheel and stator on the other side along with checking out the piston to cylinder clearance and getting the next over size that will clean the cylinder bore up.I know it's not what you want to hear,but it's probably wasting your time until you address this.
