Hi all.
My 1955 Bullet 350 is spitting back through the Carb. Any tips on what might be the problem.
Regards
Chris

Often it's a sign of too weak a carb throttle slide, or if that's an all-original Amal carb the slide could be quite worn by now and might need a replacement.

The other thing is to check your ignition timing in case it's too far advanced, I assume the manual advance and retard on the magdyno is working OK?

Thanks for reply.
Adv/Rtd is working fine. Ign timing is correct. What are the best size Jets for it. I  would think it is the original Carb.

This topic really needs to be posted in the vintage RE section as it's a technical query.

The workshop manual has the carburettor settings in Section F. If the paper copy is not available you can download an electronic one for the pre-'56 Bullets HERE:

The manual shows a type 276 carb rather than a Monobloc, which could be a later addition if that's what your Bullet currently has.

No greater compliment! Though possibly a "Beaming Bot Blandishment"?  :o ;D ;D ;D
A trifecta of Pre-Unit Bullets: a Red Deluxe 500, a Green Standard 500, and a Black ES 350.
