Be sure the vac hose from petcock isn't attached to a vent nipple. Except for the vacuum nipple being used to supply vacuum to the petcock, all other vac nipples should be capped/plugged. Assure that both of the two vent nipples exit to open air. Good Fortune! 1973 Z1 KZ900 LTD

Only other nipples are float bowl drains. Mick 1994 ZR750 Zephyr C4. Attachments: The following user(s) said Thank You: Patton

Yeah those carbs look very similar to mine, that's where my vacuum tube vents to those nipples. Mine is only on one of the nipples though which I think is correct. Where do your 1 & 4 go to? Ram air system perhaps?

Same nipples are where you would put lines to sync carbs. Mick 1994 ZR750 Zephyr C4.

Ok mate its definitely worth a go, perhaps there's not enough vacuum getting through with just the one hose and where I took off the exhaust recycle system so can't hurt to play around with it.
