Jennings reel spin problem

I have a Jennings Governor. The three reels spin but after a couple of times the first reel will only jump up one fruit and the break shoots back in, then after all goes well again for a few times it does it again. Any idea what this could be?
Thanks.

Hi Francos ......

Are you from somewhere near Stoke on Trent?
If not, no matter.

If so I've been contacted by a friend who may have sold it to you.
He's quoting the hexagonal off set wheel on the bottom of one of the brake legs.

I can't get to a Jennings at the moment to photograph it.
Basically, the clock at the back moves across a bar which trips the three reel brakes one after the other.
In order to try and introduce an element of randomness to the timing of this, the leg of one of the brakes ends in a hexagonal wheel which is off set. Thus it shows a different height to the bar each play, this lengthens or shortens the spin on that reel.
It may have stuck.

Have a squint at that, but don't forget any of the other causes as mentioned in the links Mr.P just posted.

Unless it's broken, which is unlikely, it's most likley just gummed up with dirt on old grease. If it is, simply clean and degrease it and very lightly oil with just a spot of sewing machine type oil.
Also make sure that the reel is spinning freely. To test this, take the mech out and operate the machine out of the case. As soon as the mech starts the unwind part of the cycle (once the reels start to spin) throw a piece of kitchen towel or cloth into the fan blades from the rear. This will immediately stop the cycle and the reels will spin free for as long as you like. You can then spin the reels by hand and see if they are free to spin. The spindle could have dirt in it or the reel itself might be rubbing against the brake arm (when finished simply pull out the cloth and let the cycle run through).

So I've cleaned the reels - running smother. So how do I adjust the timing?
Thanks.

Now that's another matter. Is it just the first reel brake cutting in too soon or is it all three?

Just the first break cutting in only, slowing the reel to move one place - not all the time, just now and then, after a few spins.

Is that the first reel looking from the front or the back?
