    Lightbulb Help with recommendations on Dellorto carb. please!

    I have a 2002 Aprillia Scarbeo 50 (Minerelli), I added a 60cc BBK, pipe, springs...

    I had some problems tuning with the factory size carb., so i did some research and found people recommending a Dellorto 19.

    Before i purchase one, i wanted to get some feedback on which exact model to get for my scooter, preferably one that fits without anything extra. Also, will i need to order a choke cable kit? I see some that come in a kit.

    The one I have found is a: ergaser Dellorto PHBG 19 DS 2-stroke type 02631

    Can anybody weigh in on this? All comments welcome. Never been down this road and need some guidance.

    TIA

    dellorto 16mm SHA from treatland / its tuned from the factory for regular two stroke air fuel ratio if you have the correct slide. thats enough air to hit 10000rpm with a 60cc.

    Our member jixaw has a 15mm sha on a 70cc and its nice and quiet for an open filter. he loves his... hes got the 11 slide and the stock mainjet.

    thermodynamics states that you cannot fit 19mm of cold air thru a 19mm hot hole{sport cylinder outlet}. maximum 16mm unless you pass 8-9hp wich is what the carb is rated for tops.

    you need a phva 17.5 ts with a hand choke
    the 19 is to big for a 60cc low power kit
