Sorry to have bombarded the forum lately :/. My carby is playing up and I was going to go 32/36 weber but then I had a thought (dangerous). Ive seen people use twin motorbike carbys by cutting the inlet manifold and plumbing that up to 2 motorbike carbys. Is there any magical carbys I can use on a stock a12 with extractors and not have to jet it ect? I kno I should be tunning any new carby but was wondering if there was something close enough or if someone knew what jets and springs on what carbys I needed?
