Hi Ryan, thanks for advise. Fuel tank has screw cap and plastic outlet nipple at bottom, no tube inside like most fuel tanks have. Have leaked tested tank including vent/fuel tubes and no airleaks or pin holes. Do not have a digital meter to tell exact temp but engine is VERY hot to touch by hand. Was never like this on first few tanks during break-in.
Can not see if there is an LSN as carbi barrel view (where throttle arm screwed to barrel) obstructed by boat hull but do not think it has LSN as book says only fitted on Dynamite .32...anyone know if this is correct?
