Title: Bultaco AMAL Carb question???
Post by: Curtis on November 04, 2014, 09:41:29 am
Im working on a Bultaco Pursang with a AMAL carb. My experience is with Japanese stuff so AMAL are new to me.

The little plunger on the side of the carb which im assuming is like a primer has a 4.5mm hole in the side of the plunger casing?? When you prime it the fuel comes out the hole. My question is..... was this a mod?? Is this normal?? Iv looked at other AMAL carbs and none of them have this hole. The bike still starts and runs ok. .....thoughts??
Cheers :o

Which Amal is it, MK1 or 2. A photo would help a lot.

Probably a concentric MK1 by the sounds of it.

Yes the little doodad is pushed until fuel pisses out of the hole. You are then ready to start.

The MK1 concentric wears main jets, so if it's an old carby you'd do well to get a new main jet for it.

Yea, I wish it was easy to uploads pics, its beyond me.
 Iv figured it out, someone has drilled it out and fitted a nipple on it so it can run a overflow hose, I found the nipple stuck in the end of one off the hoses.
 Is there any way of identifying what model carb it is? It has L/1036 stamped on the right hand side, with the number 11 under that. Is there a place in OZ that can supply parts for these things? Thankyou!!! :)

That sounds like a sensible mod putting a hose on the overflow.
That model number if a MK1 36mm. Bultaco Parts Australia at Toongabbie Vic or Don Newell in Brisbane should be able to help you.

Exactly, for that money it's not worth the headaches from old worn carbies.

Spanish alloy --- English design, it's a no brainer. MIKUNI always. Started up my Bully this afternoon with no dramas and idling from cold.
Life's too short for dud carby's .

Agreed on the Mikuni option! If this thing gives me dramas ill be going down that road. Where did you get the pre jetted bad boy from Jerry??

Speed and Sport. Got the adaptor there too. Aus $ bit stronger then so will probably be a bit more expensive now but well worth it in my humble opinion. If you go the CDI route speak to Peter Schoene at Bultaco Parts Australia. J
