Hi all
dual carbs are often contaminated with fuel deposits, mostly caused by evaporates that clog carby jets, airways and internal surfaces. This is particularly so with vehicles left standing in hot sun. Never buy a used old honda from a car yard without demanding the Caltex Techron 5000 treatment prior to payment. Techron 5000 will dissolve all fuel contaminates over a period of about two weeks. Patience is required to force sufficient Techron 5000 true the entire fuel system, about 500 KMS. Do not contemplate interfering with carbs physically until the Techron 5000 solution has been given time to work wonders. Once a year thereafter give the tank a 350 ml dose of Techron 5000 to a 40 ltr tank, use Caltex 98 RON for this dosed tank. I restored a Civic 1991 ed3 that was totally contaminated and inoperable in a fortnight. The dealer dumped the car with 148000 kms, immaculate one only old lady driver in 23 years for $650 as a carby overhaul was quoted at plus $1700, carbies out sent to Sydney cleaned returned and reinstalled. Techron 5000 cost me $15, car is perfect.
