Hey all. Just reading through my haynes manual on carburettor synchronisation as my bike needs doing and it suggests using a manometer or vacuum gauge set. I was looking at the vacuum types a while a go and didn't think they were too expensive, but recent searches have proved them to be slightly on the pricey side now. Can anyone recommend a good one that isn't too expensive? The pennies are a bit short this month! Thanks  |

Thanks make your own! the end of the tube go to each carb, you may need to purchase the fittings for the carbs, the liquid will be ATF or auto transmission fluid,  |

I once tried it with paraffin in a U tube. It all got sucked out. I ended up with fine jets on the tube ends but the level reaction was slow.
As said many times listening with a fuel tube or mechanic's stethoscope works fine. You are listening for which one sounds loudest. Its balanced when both sound the same so you move to the next pair of carbs.

I think a manometer would be more accurate than the old Stromberg SU dodge of listening through a tube. It never was accurate, too many variables.
Dave, referring to your choice of fluid for your U-Gauge. Many, many moons ago working as a heating fitter we filled our U-Gauges with cold tea! If we used water you could not see the level (meniscus). ;D

the trick is to use ATF fluid, and turn the engine off before it gets sucked in |
