Hey guys I bought an xlt last winter and it always started fine at first but if I shut it down for a while it woul take forever to restart it. It won't start at all now it tries but nothing. I poured a little gas in each cylinder but now it backfires so I'm afraid of it lighting on fire lol. What could be the problem Im terrified that its the problematic PTO bearing.
Check to see if your choke plungers are stuck or not bottoming out. Did it run ok when riding it or was it boggy? Also, make sure your throttle cable is properly adjusted and it is returning all the way to the block on the bars. If it's not you are triggering the safety switch. You can pull all day and it won't start. Both are easy to check and at least a starting point. If those are ok it could be your needle seats in your carbs causing it to flood. If I'm not mistaken this was pretty common with the tripps. Shutting off the gas when not running will help. Have you cleaned the carbs lately?
Remove carbs, remove bowls, remove floats and needle valve.
Look at the tip, it is most likely metal and will show some wear [it will have curved face rather than straight to tip].
Replace with the rubber tipped ones as they seal better and do not wear so fast.
mine acted like that last season after I rebuilt it,,,,started ok cold and ran well,, shut it off and was a bugger to get going again ,, ,,I got a diaphragm kit to rebuild the fuel pump,,,,seemed to be the fix,,,(it's cheap too)
