Reply to "Holley carburettor adjustment needed"

Hi Rene,

a Holley carburettor is more tolerant than a Weber in terms of adjustments. A new holley is pre-tuned at the factory and runs as it is, and your engine should start, without backfiring, and not stall below 1800 rpm, the choice of jets, nozzles and power valve, cams, etc. .. are for optimized settings. I think it is necessary to recheck the firing order, recheck the connections and the plugs on the carburettor and on the intake pipe, etc ... before drilling holes in the butterflies and returning the secondary back to adjustment of origin.
