The float bowl is cracked?

And your point is ????

no gentlemen, its the pilot fuel screw (i think), it looks different. the other 3 i have are shorter and sit more flush with the boss, where as the screw for #3 it longer above the threads. i dont know if it was just replaced with a mismatched screw by the PO, or if its the way it is supposed to be.

Strange looking pilot fuel screw. Long head should be easy to reach with the carbs installed though.

My last post was a sarky one sorry, i did spot the air screw

The air screw length above the cone shaped tip does not really matter its the length & angle of the machined point thats important as long as those are all the same & undamaged no problems

The air screw in question has been replaced btw

thanks for clearing that up. to the naked eye, it seems the same under the threads. length, taper, tip, diameter. guess im good to go, then.

Sorry to nit pick but those are FUEL screws, the air screws are on the top of the carb bodies.

Yeah, there's a lot of confusion about which screws are which.

Your photos are great illustrations of the fuel screws.

That longer one with the knurled head sure would make adjustments easier. I wonder what it is from?

[jed.only]

im not sure. i did some poking around at mikesxs and saw some similar, but not exact, and probably becuase its for astock mikuni BS38 CV carb.

fuel idle mixture screw, 256 type:


fuel idle mixture screw, 584 type:

i'd like the extended fuel screws on mine. It sure would make adjustments much easier!

Amen to that, just tweak it with tank etc still on... in past i have used those bit driver thingys, (you know all the diff things only an inch long that u fit in the screwdriver)

butr that would make life easy!

K&L replacements are long like that.
