    Re: When to choke?

    I found an old picture I forgot about.

    The paper clip trick confirms the fuel pump works and the needle and
    seat didn't open. The most common cause is a vacuum leak.

    Unfortunately it doesn't work with Mikuni's unless you drill a hole in the
    center of the diaphragm cover.

    I posted this to demonstrate that this is a common problem with all
    diaphragm carbs.

    Re: When to choke?

    Guys, this is a BRAND NEW Super Jet that 77sXZX has.....

    He is simply running it out of gas. As stated, it will take a bit to fill the lines, filter, carbs etc to get to start, and YES you need to choke....

    Simple solution - don't run it out of gas. There is NO vacuum leaks, please do NOT go poking any paper clips in the carb breather holes etc.....

    The new Super Jets do run a bit lean in the low speed circuit, and you cannot adjust the carb without removing the block off caps.

    If it takes more than 1 min to start the engine, your engine is officially hard
    Thanks all. I tried this yesterday and it started up quickly

    I usually choke after a bad hit.
