Altitude adjustments

    Hey all.

    I’ve got a 1994 Honda acty (the van, street version). I live at about 5500’. Van was imported straight from Japan with no adjustments made until it arrived here. Psa: I know very little about carbs, but recently replaced the air solenoid.

    I know in the manual it says to adjust the float/ rejet after 2000 ft. Van seems to run fine enough as is (that is, being slow haha)

    Has anyone done any of these adjustments/ have any suggestions? I can’t seem to find smaller jets for the carb. I even have thought about throwing a performance air filter in there just to get the engine a bit leaner to see if that would help.

    I know speed isn’t a big concern in these guys but I have 1 hwy exit to run on my way to work so I’d like to get it a bit faster if it’s possible. Definitely spooky as is.

    Run it for a bit and check the plugs. If they are sooty, you are too rich.

    Not sure who makes youre carb. Jets from motor cycles sometimes work.

    sadly I didn't take a picture of this when I rebuild my carb. #3 the metering needle valve might have an adjustment on it. or you might "find a way" to lower it. that would lean the mixture. this carb is much like motorcycle carbs, and that is how their adjusted. edit looking again and trying to remember, I think there is a c clip and grooves.

    Sweet. Thanks for the help! Might just have to open it up and see. Anyone know the part number of the jets? Might be able to find some in a motorcycle kit.
