Good that you found it.
Must have been getting somewhat hot and bothered inside - hence the reluctance to start again.

The final proof will be in the fixing ....

I just put the bike on the lift and tried the old cigarette paper trick. It was not possible to remove the cigarette paper from between the points until the rubbing block was about 30° past the opening ramp! I did not set it like this, but I will correct this.

Strangely the bike does run okay like this, it simply has issues with hot starting.

Thank you again to those who have offer kind advice.

Probably best to be sure the magneto advance diection is still the same direction the maker intended ......I can tell by the change in exhaust note  if ignition advance is right.............the army bike instructors used to do a trick of flooding the M20 carby and kicking the bike on full advance .......the carby would catch fire and they would pretend not to notice ........then when the fire was getting a bit big,retard the mag ,kick the bike and suck all the flame into the carb.......they reckoned that the motor would always start with the carby on fire.

A late A10 should be alternator with the 4 spring Triumph cluctch....not the six spring pressed tin BSA clutch...........anyhhoo,people replace the clutch with a Suzuki one ,cant recall which ,but the swap is well documented.........Incidentally the dragging clutch will smash your gearbox gears apart.,and sharp gear chips will score the shafts.............To cure this problem ,I fitted an army beezer clutch ,this freed easily,but tended to slip under power.,just had to ride the bike sedately .............Anyhoo,when I sold the bike ,it lasted only one day , and was on the news that night..........he tried to pass a bus on the inside as it turned left .

I've set the pressure plate run-out with a DTI, and you don't get a squarer lift than that.
Into Neutral before rolling to a stop is pretty much essential on many old bikes.

First, thanks 33d6. Do we need to know more or do we know enough? Nah, I think we know enough.

My best advice to Waratah owners with Waratah painted on the tank is to not re-paint it, or if you have to at least document the original paint. If your bike has original paint, R, at least we know that that particular bike had a double pin stripe. My guess is the Powerhouse Museum example has been repainted. It may have had a single stripe originally, but without documentation, hard to say.

Finally the "1934" 250. Nice and tidy. I'd question the date, because the alloy-head (three bolt) sports model was "all new" to Waratah in August 1935. So hard to date the "Waratah" aspect of the bike before 1935. But what if it has numbers in keeping with a 1934 Excelsior??? I'm putting that in the "i don't need to know" category!!

Cheers

Are you guys ensuring that the clutch lifts perfectly evenly and squarely ?

If it worse when hot, then things have expanded a bit.
Backing off the springs a shade may be required ?

Are you snicking into neutral in the last bit of rolling to a stop.
And tried changing the gearbox oil....

The OP could do the "quick and dirty" test to see if the problem doesn't lie with the mag or timing, namely set to TDC on comp stroke with lever fully retarded, then move lever incrementally advanced to find the best position and so prove the rest of the engine, carb etc.
If nowhere within that lever range produces a good running engine then you need to look elsewhere.
At full advance of the hand lever the timing will likely be too advanced so will need resetting at some point.

I've found the six-spring earlier clutch is even worse.
I've done all the things you have and now accept that it's as good as it's ever going to be. This is on an early Goldie, and spoils what is otherwise a great bike to ride.
Conversely the clutch on my plunger A7 (the earlier enclosed type) is as nice as that other much-maligned clutch, the Velocette, ie, very good.
That's a nicely engineered unit (unlike the cheap-arse BSA things) but the set-up instructions need to be followed to the letter, and many seem unable to do that.

And this looks to be another 250.
1934, Orange NSW, Villiers XVIA engine
