I know it's a small item, but I was wondering if anyone has an extra carb drain screw they could part with. I think the threads on my right float bowl are stripped. The screw still goes in far enough to keep the gas in, but I stripped the head of the screw trying to screw it on too tight. So I at least want to replace the screw, but wouldn't mind replacing the entire bowl if I can find one used.
I was also wondering, is there a non-stock screw that will fit the float bowl, that I could pick up at a hardware store?
I have a parts carb. Someone is interested in a cap. Both drain screws went to toogoofy (she might have a spare now?)
I could take it apart and let you have the bowl. Tonight I'll take it apart and see the condition of the innerds. All screws have good heads so I don't think it was ever taken apart much. Just one butterfly is rusted stuck.
The screw is almost certainly a standard metric size. If you take the good screw to the hardware store they could probably find a replacement.
A vernier calliper and a tool called a thread gauge are useful if you want to measure up screws at home. The gauge looks a bit like a set of feeler gauges, but it actually has a bunch of small toothed blades that can be matched up against the thread on the bolt, or inside a hole to measure the thread pitch. Use the vernier calliper to determine length and thickness, and you should have no issue finding the right bolt in the future.
I have a 3/16" thick metal screw sizer. I can check that way - "which hole will one screw into?" I'll take the screw from a spare set of good carbs and check the threads. Like burning said, then use your calipers to get the correct length (but longer would work, shorter wouldn't).
It appears the taper on the end of the screw is what does all the work of closing off the hole. I don't think a stock screw would work because of that.
Maybe use a dremel to cut a new notch in the head for a screwdriver in your one that's toast?
Thanks for the replies. I forgot about the tapered end, that would create problems with a standard screw replacement. I do have a dremel, so I'll try cutting a new slot into the one I have. I wish I had remembered this when placing an order for a bunch of parts from Bike Banbit. That order shipped, and if I bought a new one from them the shipping would cost more than the screw :confused:
