I DID have one carb kit with 2 different length float needles.

Thinking the shorter one may not come up high enough to shut off the fuel into the float bowl.

You can try blowing into the carb as you rotate it to see if the float valve stops hissing.

(since you have an extra one to play with)

I've also hooked a clear fuel line to the float bowl drain and hold it up alongside the bowl to
see how high the fuel level is.
usually somewhere at or below the joining surfaces of bowl and body.

I frequently forget to turn my gas on and the things run perfectly until they run out so setting your float level a little low is better than leaking, if overflow is your problem. or more accurately, overfilling.
Not sure if there's an easy way to adjust the float levels. Maybe that's why they make different length float needles.
The older ones had metal tabs you could bend slightly to change the fuel/float level but I think the 200 carbs are plastic and will bend once before breaking off. (It's been a while since I've messed with a 200 carb)

Make sure your fuel shut off works.

It can leak fuel into your crankcase and actually fill it up diluting the oil etc.

and all because of a tiny float valve.

Let us know.

I have one just like it right now and I'm going to just blow air (and mystery oil)
into the fuel line with the drains cracked and see if it helps.

Getting extremely lazy with this weather.

+1 yeah you cannot adjust the 200s carb float, this is all fresh in my memory since i have had problems with my 84 200s. first things first make sure your gas tank doesnt have dirt in it, any dirt at all will jam your float needle causing fuel to constantly flow into the bowl. If theres no crud in your tank check your fuel line, If thats ok then remove your carb then remove all jets + float and valve. clean all with carb cleaner. when you remove the float valve check to see if theres any dirt clinging to it and around the float valve seat. blow air threw the fuel line and clean the valve seat. then reasemble the float and valve, move the float up and down when installed to see if the valve sticks. if it doesnt then you should be golden. clean all jets and make sure you can see day light threw them.
Reinstall carb and you SHOULD be good. if not then i would think its either your float + valve or your valve seat.

Almost forgot, I usually use a clean test tank or clean the orig tank complETEly when I do a carb.
Tanks get screaming hot water, soap, shampoo, cream rinse (just kidding) pressure washed out or steam cleaned, radiator shop, muriatic acid ... whatever it takes to make them stop throwing chunks and then baked on the bbq or woodstove till bone dry and THEN
hook 'em up to a nice clean carb.

Good point 84H200s

Sure doesn't take much rustdust to hang them open.

There might be a screen in the fuel shut off, and I usually run a foot or so of clear fuel line and let it loop way down by the shifter to settle out anything that might be in the lines/tank along with a clear filter.

I'm just sick of tank rust and the 85 carbs are fun and interesting but a huge pain to get on and off compared to the 84 and earlier.

I bet I've done 10 85+ carbs this winter and just do not enjoy getting them on or off.

As I recall, the 84 carbs can come off, apart and back on in 15 or 20 minutes.

i didnt know there was that much of a difference. i pull my gas tank off and seat, unbolt the 2 10mm bolts and loosen the carb boot clamp. yeah about 15-20 mins. Any luck with your carb over flow problem?
