hey everyone I am having a problem with a 1993 xlt sp w/ a 580 tripple that after warming up the sled Idles at a very low rpm and wants to die all the time . my question is how do I adjust the idle speed ? when I first start it, it idles at around 1200 rpm,then when its been going for a half hour or so it wants to die unless you manually feather the throttle.
You should have an idle adjustment screw on each carb or if like my sled I have one that adjusts both carbs.
I'm not real firmilier with tripple's but some one on here will have probably a better answer than me.
But you should have the adjustment screw there somewhere.
Ask Madcow if he cleaned the pilot jets with fishing line or strands of wire. Idle to 1/4 throttle is your pilot circuit. I would make sure those pesky pilot jets are clean before doing any adjustments.
If the needles and seats are replaced... A very common problem to have go wrong on the XLT Id say that this is a problem with the adjustment screws... Its sounds like its getting too much fuel maybe and is flooding itself out when its warm... This sounds like a loading up problem to me.
