96 xlt wont start please help

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.
Thanks guys

Eric

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?

Try shutting off the in line fuel valve before switching off the engine, I'll bet you have needle valve seat wear that needs fixing.

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.

Like RJ said. Also under your exaust manifold there are 3- 10mm bolts. One for each cylinder. Take these bolts out and drain the crankcase. Prolly filled up with gas cuz of badneedleseats incarbs
