Hey all have a XR 100 here won't start. When u kick it 4 or 5 times it seems to backfire but more of a phewwwwww sound from exaust. I just bought I trying to get it running. The PO put a new carb in before I bought it. Tried starter fluid and still won't start. Definately spark from spark plug. Any suggestions would be appreciated.

Thanks

Is the carb flooded? Maybe a float is stuck is the carb...when you remove a spark plug does it smell like gas or is the plug contact wet?

Mike

Sounds to me like it's firing 180° out.

no the plug is not wet though when I remove the plug I can smell the gas. I checked the flywheel timing and when its at TDC the piston is at the top. Not sure how else to check the timing. It is a brand new carb. I do have the old carb. When I went to buy it from the PO i kicked it a few times and it did start to idle as soon as I gave it gas it stalled. I figured this would be an easy fix but I am stumped

Check the valves on it.
