My engine is tuned not sure to what extent, 652 126 with lumpy cam, 123 ignition the guy that fitted prior to me buying it. He fitted a Weber 40 which by the consensus of the forum is too big, but as it's there i might as well leave it on. At the moment it has a k& n type of filter but I noticed a lot of people fit trumpets rather than a filter apart from the obvious danger of sucking in debris are there any benefits of fitting trumpets? if so does length matter?
If driven without either i have noticed the occasional flash & popping exiting from the carb.
