Setting float Heights

That's it, I'm pulling the sodding carbs off AGAIN, I've watch umpteen video's of setting float heights and they all seem to contradict each other, every time I pull the carbs I'm marking the repainted engine cases and I really hope this is the last time, so this time I'll get the vacuum pump out as well and pressurise the carbs checking for leaks, I'm finding that, do it properly, do it once, yea right I've heard that somewhere before, I thought I was ready to go out for a test ride and shake down, maybe later.lol

Nurse Julie:
If you stand the carbs up on their end like it shows on my guide, you can't go wrong. And if you still can't get them right after following my guide, then you haven't been following my guide 😁😁😁

I feel like I'm chasing my tail, I watched all the vids, carb float bowls off at this point I used a vacuum gauge to check for any seals leaking and ended up using 2 of my old float valves, after I was happy with the test, I reset all the float levels, yes the carbs were end up with just the tang touching, all clamped back up bench test for fuel leaks bugger no 4 carb over flow, carbs apart again no 4 over flow leaking, changed the float bowl, clamped up again, petrol on, petrol everywhere, quick tap with screw driver and a shake all's well. Carbs back on bike and bike running but I think it's no 3 over flow drips a bit, not so much when running just if I leave the petrol turned on and not running, is this worth another carb strip.

I did all that all on the bench before and after assembly, even using a vacuum gauge but you have to use some petrol or WD40 to get some sort of a seal, I can only assume the height on that bowl is slightly high unless I have another weeping float bowl over flow pipe.

wildtapholer:
I'm still not happy, so I intend to pull the carbs apart again and use all the original brass work, recheck the float heights and check all float bowls again except for no4 I've already changed that, I'll just have to be really careful taking the rubber seals of the new brass wear when swopping them over.
