1930 Model B

Postby Johnguppy » Sun Sep 23, 2018 6:47 pm

can anyone help with parts or information , I have just purchased a 1930 model B

I am missing the front brake rod , could anyone let me know how long the rod is please or does anyone have one ?

Should the cab have a 1/4" fibre spacer to space off the carb , at present I cannot remove the float chamber as it hits the mag pick up HT connection , not a good idea if you flood the carb

thanks
john

The length of the brake rod will be found in the parts book but note that it is not easy to make, being fashioned from a 3/16 dia rod with a 26 tpi thread. The threaded portion is then rolled in order to put two flats on it thus causing the thread to increase to a bastard 7/32 x 26 tpi.
They are available here https://draganfly.co.uk/index.php/a65an ... rder-forks
Again a parts book should tell you about the carb spacer but even if not originally fitted they are a good idea. A spacer will not prevent fuel dripping onto the spark producing device, this was done on purpose to ensure that owner's had to buy a new bike every now and then to replace one that had just burnt to a cinder!

Carb spacers are always a good idea. There main purpose is to reduce heat from the engine transmitting to the carb body. Mainly old bikes never had one and can't be fitted as the carb stubs are way too short. I always remove the stubs and replace with either bolts or new stubs so a spacer can be fitted.

Just a thought about fitting a spacer on the carb manifold.... the 30 B has a very long manifold neck, I suppose the spacer should be made from something hard to make sure the carb does not become a pendulum.

Not all Ariels need a heat spacer, if the carb stays to cold the engine will not run as it should.

Thanks guys , it seems the previous person had assembled the brake rod incorrectly and one I had looked at it its fine now

regarding the carb spacer the problem is I cant remove the float bowl as it sits right above the mag pick up . it does seem I have the correct mag and carb fitted so I have added an 1/2 spacer but not sure what went on oh I did have to make new studs

Just finishing the wiring and I will see it starts

Does anyone know where I can get a exhaust valve cap that screws into the cylinder with the cooling dome ? or does anyone have a s/h one they would sell me
thanks

Try Pat who runs the black ariel spares for the club for the exhaust cap.
