I have a 98 Polaris Trailblazer. I pulled the carborator apart and cleaned it up, but didn't replace anything. I put it back toghether and started and ran fine for a while. After it set for about a week I went to start it and I had to crank it over for ever before it finially tried turning over and ran fine. Then I let it sit for a few hours, then same thing again. Takes forever to start! What is happening, seems to be takeing a long time to get fuel or something. I didn't make any adjustments or anything, just took it apart checked the jet and sprayed the outside down with carb cleaner.

 

if you didnt clean every little hole and passageway in the carb you may have broke something loose and it got lodged in a hole somewhere. check your choke circuit and make sure its clean unobstructed and not sticking closed. your could have also bent the float a little bit causing it to flood the motor while its sitting.

 

I unscrewed the jet out and checked it then screwed it back in completely, should it only be screwed in part of the way or does it matter?

 

Compression check!!!!

 

what jet are you talking about?

 

Did the bike start OK before you tore into the carb or did you tear into the carb because you had starting problems?

If your hard starting problems started <u>after</u> you messed with the carb, then thats what I would be looking at.

If this is the case, you messed something up so go back and look closely at your work. The two jets inside of the float bowl should be snug, don't over tighten them as they are hell to come out again, if you do. Also look at how you mounted the carb to make sure it is clamped correctly, so as to not have any vacuum leaks.

Hard starting (if carb related) as you explain it, usually is a lean condition, so look at the choke or primer if yours has one. Like you have already said it sounds like it is not getting fuel.

If it was a flooded condition, a cold engine would most likely fire up right away and then die and not start again.

Well, it wasn't running very good to begin with but was starting fine. So I took it apart in hopes of improving it...which it does run smoother.....but ended up with starting issues now. I bought this quad used and have been fixing it up. I will take the carbeurator back apart and check things over again because logicially that is where the problem is.

 

Take out every jet and clean well with carb cleaner and compressed air, look inside the fuel tank for any sand or rust, it only takes one small piece to plug the pilot jet which sounds like your problem.
