Today I finally was able to put the carbs back in my bike, but now there is a small amount of gas dripping from the bottom of the carb where the float bowl is (from a little hole). When I turn the petcock to RES, a stream of gas comes out of those hole. Have I done something wrong with the hose routing, or is there something wrong with the carb itself?
Did you close the carb drain screws? They are a special screw with a tapered end. Can't use a standard screw.
anyway - been there. Put things on. Turned on gas and GAWOOSH! gas pouring out the carb drains like crazy. WTF! Forgot to turn in the drain screws. Can we do a face slap?
Could be bad gas seals at the point where the carbs join at the gas inlet. I had that happen to me and that's where it dripped from. If gas is flowing while the bike is off and on RES then your petcock may also be bad. When you get those issues sorted, check the float height with the clear U tube method as well.

Haha, I think it's the float bowl cover you sent me. So I can't tighten it with just a normal phillips? I'm going to have to hunt down one of those japanese screwdrivers. I hope I don't have to adjust anything in the carb itself. It was a B**CH to get back on.
Float bowl screws can be anything. Is the gasket in right? Is it leaking around the gasket or the carb drain hole?
If it is the drain hole, then it does need the right drain screw. It should have been in it. Maybe it is dirty at the tip and not closing it off.
If the drain hole, you can cap off with a nipple and if you need a new drain screw, I can send one. It should have been in the float bowl. Or take the drain screw out f your old float bowl.
So exactly where is the gas coming from? Drain hole or around the gasket area?
It's the drain hole. The gas also streams out of it when I try to start the bike.
Where does the drain screw go exactly? In the drain hole?
I added a mark to show the drain screw but Photobucket hasn't updated it yet. Maybe in a few minutes.
It is the hex head screw with the phillips in it that points to the drain hole in from the side.
May not be hex head, but usually phillips (JIS) screw going in from the side. That's how you drain the carb bowls before removing them.
Same place on old and new carbs.

That's the problem, there's no drain screw in that float bowl. The reason I couldn't find the drain screw is that the bowls are reversed :o I think I did that by mistake, no paying attention to where the screws were located.
The bike won't start without this screw in place correct? Is there something I can put on the drain to stop the flow for the time being?
I threw out the broken bowl cover not knowing there wasn't a screw in the new one.
You can plug it with a nipple or tiny piece of hose pinched off. It needs to be there or the carbs drain.
You need to reverse the bowls so you can get at the drain screws. You need that also to check final float height with a piece of tubing.
After you do that, you can remove one screw and look at the end. Probably can take a screw and carefully file the end to match and use that on the other bowl. Use brass screw as I think they are brass. if not use anything. Don't screw in too hard you don't want to strip the hole.
Or use most anything for now to plug things up to get running.
PM me your address again and I'll mail you a screw tomorrow.
I've also noticed that I have the throttle cables reversed. This would affect starting as well correct?
