1989 suzuki lt-250 4wd

I recently rebuilt the top end of the motor and rebuild of the carb. It was smoking real bad and hard to start. Now it starts right up and shoots out white smoke and oil out of the tailpipe. It also idles fast with no adjustment on the idle screw . What can be my problem?

Thanks

I had the piston replaced and the cylinder fitted to a new one and the head finished by a service shop and

I bought a carb rebuild kit from e-bay and cleaned it and put it all back together.

Vacum? Which hoses would that be?

Thanks Dennisg

check your boots on the carb:yes: check your head pipe connection to the head Check your carb again ! Blowing white smoke ? check your head gasket JMO

I have checked the head and the pipe and it is tight with no leaks. The carb boots , it seems that it does not make any difference weather the boot is connected or not, just runs fast at idle with no adjustment. I assume that you are talking about the boot that goes to the airbox.

Thanks

No I was thinkin the one that connecets the carb to the motor If you checked all that stuff then I would go back in to the carb The white smoke is puzzling to me !! Dou have any pics of the quad ?

It is a 4 stroke. It is like it is possessed or something. The carb screws should work and the overhaul should have stopped it from smoking. It is just the same as before all of the work.

People say that it needs and overhaul and the carb needs to be rebuilt, but both of those have been done. All of the hoses and boots are in good condition. It runs too fast and the engine spews out white smoke.

Thanks

It is air cooled. The rebuild was two months ago, that is how long I have been trying to get it running right. The rebuild was just the top end, with new piston and rings and head with the valves reground. Keep the questions coming maybe we can figure something out.

Thanks

Do you know if you put the rings on the piston in the right order.For the high idle Double check your throttle cable to see if their is an binding sometimes where it goes into the carb can be a little tricky. Does your throttle work smoothley. Even if your head is tight does not mean the gasket did not get damaged when you put it back togather Did you torque everything to specs and with a head you tighten head bolt alittle at a time lets say the specs say 25ft. pounds torque you would set your torque wrench at 10ft. pounds and tighten each head bolt in a cross pattern or x pattern and continue these steps till your at 25ft. pounds. Did you do it this away?

      Hi everyone. 
      Let me explain the thread title. 
      My husband and I are very active in the nudist community, and we have stayed at many and most of the mainstream nudist and clothing optional campgrounds in the USA. We are now approaching our retirement and would like to start a podcast to share those off the road / backwoods / little known camping areas where nudity is allowed. We have purchased a 5th wheel camping trailer with a rear garage for the ATV and now need some good reports on the one to buy. 
      We are most interested in a side by side unit but would love to get your thoughts. 
      Feel free to stop by and say Hi and ask anything you would like to better understand what we are looking for in an offroad unit. 
      Thanks for reading and hope to hear from you.

      Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?

      From Arkansas. Just bought a 2012 Gator 850i RSX because I could not pass up the price. BUT it has an idle problem. So, to be honest, I joined just to get a service manual. I have a choice: 1)Buy a hard copy: ~$100; 2)Buy a CD ~$35.00; Get a direct download for free posting 10 times; or get a download for $29.00 (subscription). Haven't decided what to do yet.

      Hi Guys!

      New member and could really use your advice. I would have to believe this has been an issue for others but a search here came up with nothing......? (Probably me not doing search correctly)
       
      I have an 87 Big Bear 350 YFM350FWT
      The OEM Mikuni BTM carb is shot and would rather replace than rebuild.
      It is no longer made and I have had good luck with NICHE carbs so I ordered a #K-CRB-0006 This was what they said was replacement when ordered. This Carb only uses 1 Throttle cable. The Slide is linked so it uses one. (OEM had 2nd cable coming through top to move slide)
       
      Problem is when I ordered a replacement Cable from NICHE (#C-CBL-0061) the Cable wire is a little short, not allowing Throttle to return all the way down to Idle position. I called NICHE and they are at a loss. Haven't gotten back to me after 2+ weeks.
       
      What would you recommend other than a carb rebuild?
      Can I just use 1 of the OEM cables (It is the right length) and snip/disconnect the other that went to top of Carb for Slide?
      Or ??
       
      Thanks in advance for any advice you have!!

      Howdy y'all, I'm trying to fix a neighbors 2015 Brute Force 300. Came in with hard to start and won't idle except on choke issue. I pulled the carb and found the pilot jet as well as the emulsion tube partially clogged. Cleaned up everything, put it back together, still having issues...  It will start right up on choke and will also start off choke if you give it just a touch of throttle but it absolutely will not idle unless it's choked just a touch. Also, excuse my ignorance but I'm assuming the "dial" thingy attached to the carb that turns in and out is for setting idle??
