PHP Warning: Use of undefined constant VBA_SCRIPT - assumed 'VBA_SCRIPT' (this will throw an Error in a future version of PHP) in ..../includes/functions_navigation.php(802) : eval()'d code on line 1 Can I leave the throttle on?
Yeah don't leave throttle on as it will wreck your butterfly return springs in the carby. also with the butterflys' open more air will circulate and you may get more dust or moisture which will lead to problems.
You've got the right idea just get the cover modified
