Coud you guys give me a pointer on where to start fixing a backfire . it only happens at high revs , i have been tweaking the dizzy over the last few weeks to try and sort the old carbs running issues , since the new carb has been fitted she runs far better but will not idle properly and backfires at high revs . should i start with points , gap timing etc , she has new plugs , leads, points, rotor arm and dizzy cap and as i say a new carb . Thanks in advance ,Malc
Ok will do , any tips on how and where to start looking , all pipes seem ok and connected properly , i have read about using wd40 to check for airleaks - any tips on how to do this please .
WD40 makes a mess. Use carb or brake cleaner. When I do it the engine slows if you have a leak. Others disagree ^. Find out for yourself - spray a squirt of your chosen leak detector down the carb and see what happens.
