Idle Mixture Setup Zenith 48 VIR Carburettor Bedford 300 214

Update on the rebuild of the carby and setting the fuel mixture at idle. Also, I found out why the mixture at idle was always to lean and would cause "dieseling" or engine run-on, whereby the engine keeps running for a short period after being turned off, These carbs were used on Bedford 300 and 214 petrol 6 cylinder engines from about 1958 to 1967.
