    Hi there. How you proceed on dual carbs. On the video you only adjust on one. Thanks

    Is the Gastester discontinued? I see them for sale from a few vendors, but they’re not on Gunson’s website.

    It looks like you used the gas tester to adjust the mixture screw. Is it possible to use the gastester to assist with jetting? And if so can the secondary jets be set somehow? I’m assuming the idle jets could be easily adjusted but to get a reading on the secondary part of the carb you would need to give it gas and drive it down the road. Just wondering how I can make that work.
