    1995 SPX help

    I have a 1995 SPX. Starts and runs mint. After riding for a while it bogs and runs like crap. The rear cylinder spark plug fouls. Any idea why?

    Clean & rebuild carb & replace any grey fuel lines that have the name "Tempo" on them.

    don't use the ski again until you do that.

    You’ll want to check the fuel valve too

    I typically have had to replace them

    Look for green residue on the brass connectors

    Just an update here. The ski run great as long as you want. If you shut it off when it's hot iscwhen there's the problem. Hard to start andcthen it bogs.

    That sounds like leaking needle and seat then

    Shut fuel valve when you stop engine

    Turn it back on a moment before you restart

    If it behaves that’s your answer

    Could also be worn out rotary valve
