I have a 2003 predator 500 that is a real pain to get started when cold. If I can get it started at all. It has spark, is getting fuel, and cranks like normal. I have disassembled and cleaned the carb. Have also tried switching out the carb. No noticeable change in attempting to start. Have swapped out spark plug and made sure the gap is set correctly. Have looked at fuel pump and appears to be in working order. Have taken to air tube off and noticed a lot of back pressure out of carb. Does anyone have any advise for me or come across the same symptoms?
