Title: Carb Set up Specs. Post by: Warks_Dubber on January 19, 2014, 01:08:24 am Evening all
Hoping someone could give me some advice on setting up my 48IDF's for my 2276cc engine? I am running 82mm crank, 1.4 rockers, Wedgeport heads.. Hoping to set CR at about 10:1 From what I know the carbs are currently as sold in spec... which is: ◾40mm Venturi ◾150 Main jet ◾F2 Emulsion tube ◾180 Air corrector jet ◾0 Pump exhaust valve ◾55 Idle jet ◾50 Pump jet ◾2.00 Needle valve Is this ok? does anything need to change? Thanks as always. Jas. Title: Re: Carb Set up Specs. Post by: ED2.4 on January 19, 2014, 16:24:13 pm Hi,
with 40mm vents ,i'd go with 165/170 main, 200 air 60 idle jets (maybe a bit fat,try 55 first ) F2 tubes are Ok ,50 pump jet and 200 needles too, float level set at 10mm closed, no more than 5 psi fuel pump pressure |
