Advice on buying a carb

the 44hiff looks a big carb but su's work differently to other carbs like downdraft type.....you will never see it fully open even though your foots is all the way down the vacuum dashpot will never open fully even on autograss racing k10 doing 7500+rpm
 
don't mess about changing the dashpot spring or anything in the carb,,,use standard engine oil in the top damper......try and set it up without doing anything to the needle,,,1st get it to idle,,,ie set the throttle stop so the engine is running around 1000rpm and then wined the mix screw in or out only 1/4 turn at a time and find a point were the engine rpm is at its highest....then bring the idle down to around 800rpm by the throttle stop adjuster......
Then try it............let me no what its doing after a road test
 
Thanks for this ! I now have another car as a runaround , but it helps because it means i can take my time and do this k10 exactly as i was it , ill be slow progress but it will get done in due corse . When i get my car back i will keep my blog updated with the SU on it
