B100 valve adjustment, clearance specs needed

[stoeptegel]

Hi,<br /><br />I have a Honda B100 longshaft and need to adjust the valves. Can anyone tell me what the clearance specs are?<br /><br />Background info:<br /><br />The engine runs fine for a while, but when hot, it stops. I have been told the valves may need adjustment.<br /><br /><br />>> EDIT >> Bought a manual (here) adjusted valves but found problem to be spark plug cap contact problem.<br />>>END EDIT>><br /><br /><br />Thanks in advance,<br /><br /><br />David
