Needed New carb for justy (or Weber DGV)

[Justasubaru]

My Justy's Hitachi carb is possessed. Idles when it wants to and at the RPM it wants to IF it decides to.

Completely drives fine other wise. So I went and bought the required adaptor for a weber. (was hopping to find a good used one locally) That didn't work either

SO I'll try you folks here before i pay out north of $220 for a new one.

Anyone have a decent working weber or early Holley 5200 for sale??

Apologies if stating the obvious here.

Harbor Freight sells an inexpensive ultrasonic cleaner. Worked great on some motorcycle carbs and a lawnmower carb using some mild detergent. No solvents to attack old rubber or plastic. Turn the carb over a couple of times while immersed to get at all the little passages inside. Watch close and check it frequently at first - sometimes the carb body really is that cheap pot-metal and it’ll start to dissolve! The t-junction for my 4-carb fuel feed did that.

A rebuild kit can also help if any gaskets are leaking or needles/jets are worn. Sounds like your idle screw might be, if cleaning doesn’t clear it up. Never scrape bonded gaskets off phenolic, though, unless you have a resurfacing plate and a lot of patience to polish the scratches back off. I had to replace the phenolic spacer on my old FJ-40 carb after scraping it up.

Vacuum leaks can also muck up an idle, also ignition advance.

Good luck!
