Check your valves, sounds like they could be getting a little tight. Tight valves will only get tighter when the engine warms up, and then you will have a bear of a time starting it. Hope this helps,

Also make sure the not start isn't clogged....... Although mine start hot without it so it's most likely valves.

If your valve clearance checks out ok you may need to adjust your idle mixture screw. If you don't know what or where it is there are plenty of threads that will help out if you do a search.

You can check them youself easy enough but if they need re-shimimng some special tools are needed.
