doesn´t start when is hot

[jorigz]

may be somebody can help me?
which could be the reason that my monster doesn´t start when the engine is hot.
i have to wait until it gets cold again and then it start whith the first intent

It could be running rich, try starting it with throttle half open see if that makes any difference.

[jorigz]

yes it tries to start but doesn´t do it

[gremlin]

maybe your valve clearences are too tight. when the engine is hot the valves could be hanging open

[jorigz]

does it is dificult to adjust the valve clearence?
