Hi guys. I have an 84 Rampage that has developed a stumble or feels like a lack of fuel. I replaced the fuel filter for staters, but still have the same issues. Where should I look next? Thanks in advance!

Welcome to Allpar. Worse hot or cold? Check fuel pressure? Have you proven fuel starvation or is it just a stumble?
Timing correct? Cap, rotor and wires in good condition? Correct Champion RN14YC spark plugs ?
Any carburetor rebuild history?
