I'm Becoming A Bother Here, Getting My Lil Landy Running Sweet Arnt I
Just A Lil Problem, Looked On't Forums And No Thread So Far, Getting Misfires At Higher Revs, I'm Doing The Obvious And Changing The Fuel Filter But If That Doesnt Cure It Is There Any Other Possible Causes?

assuming it's a doozel, then I'd be checking the lift pump - if it's on the way out, it may not be able to supply enough fuel at peak demand.
