Good point about the filter. I will check it tonight.

As soon as I remove the cover it runs perfectly. I will check the intake tonight and try and see if it is blocked somehow. It is deffinately the air cleaner cover which causes it not to run and not the filter because if I remove the filter and replace the cover it still wont run.

Thanks for the pointer about the idle air bleed set up. I'll leave it as it was set originally.

lets just hope the intake is blocked somehow.
