Does anyone have a throttle body synchrometer?

[natben]

I am looking to buy one of these but before I do does anyone have one they no longer need/use that they want to sell to me?

In your other thread you said you balanced the throttle bodies, how did you do them before. Just curious, presumably borrowed.

I borrowed one before, but I can't keep on asking for a loan of it. I should really have my own one.
I am happy to buy a new one but if someone has one they do not use anymore I would take it of them.

I've bought one,

Found one online at a good price.

I' went for this one.

Hoping it eventually stops raining so I can take the car for a drive get it up to temperature then do the balance.

I would like to balance them next week if it stops snowing/raining.

I am going to balance them at 2000rpm and see if it smoothes out the hesitation I am experiencing between 2000 and 3000 rpm.

You wont be able to do them at 2k revs, the gauge will go off the scale after about 1400 rpm.

Ahhhh, thanks for that Clifford , should I just warm the car up and balance the bodies at tickover 800 rpm?. I thought I read on here that someone had done it at higher revs and smoothed out his hesitation problem, but pissed of the neighbours doing it!!.

It depends on the calibration of the synchrometer.
Most of the e bay ones go out of range on our engines very early on.

I've got a synchronometer very similar to the one you've purchased judging from the photo. It works well but you'll need to cut down the tapered rubber seal as the butterflies are much closer to the lip of each throttle body than in other cars/carbs. If you dont the tapered seal touches the butterfly which either a) pushes the syncronometer away and stops the air seal or b) moves the butterfly creating an erroneous reading.

You could try a Gunson Carb balancer? I havnt used it for this purpose, but it works well on SU /Weber Carbs and can be adjusted to flow a lot more than 14oo rpm.

I bought one (cant remember the brand offhand but they all look the same anyway), the difference was - it came with 3 adaptors for different throttle body sizes. Think it was £30-£40ish.

One adaptor fits the circumference of the speed 6 tb perfectly without the need for cutting, and still slides under the bulkhead for cyilinder 6...it sits on top of the TB's lip rather than sitting inside...

Looks just like this one.

Think the outside diameter of the TB's if 56mm from memory??

You could always make your own, search you tube for diy motorcycle carb balance.

I used to borrow on the rare occasions I needed gauges but when the owner was away I made a set from aquarium tubing,old skirting board and atf fluid.

The beauty of this setup is that you can rev as high as you like and because the measurements are comparative they are extremely accurate, plus once set up they are calibrated forever.

Its probably a bit more faff to make a six cylinder set but if the speed six setup is like a bike then you can set the first pair then move one pipe to successive cylinders in turn using the first as a master reference if you see what I mean. This way you only need one piece of tube.

I balanced an old Ducati this way and it is so quick and accurate compared to flickering gauges, the whole setup cost less than £3.

Hi George PM Geo on here.

Also George as well, he bought one to do his Cerb but now it is sold on he might part with it.
