I did find out the carburetor was designed for 1960's Ford Falcon and Mustang. The minimum of 140 cubic inches. Well my little ASPENCADEdoes her best to breath right. When you sit at a traffic light for a short time the idle starts to load up. I have thought of trying to find a Carburetor for a smaller application.
Any Ideas,or experience with this??
Experience with fuel system design, yes. It makes no difference what the size of the original engine is. 140 CID = 2295 cm^3 but that is meaningless. Carburetors have no way of knowing what size engine theyre on, they. Fuel metering is controlled by air flow, not cubic inches.
That carb could care less whether its on a 1200 cm^3 engine wide open or a 2295 cm^3 engine half shut down. It spits out fuel based on airflow and nothing else.
Yes, put a single motorcycle carb on a large V-8 and its not gonna work, because the engines airflow is much more than the carb can supply, but the opposite is not necessarily true. Put a small carb on a large engine and the AFR goes rich. Vice versa, it goes lean.
What was done to properly design the intake manifold
? This sort of thing (half baked motorcycle concept) usually goes something like "manifold volume too large and too cold so the fuel distribution is poor. That will kill idle quality faster than anything.
I put a Holley racing carb on a 1200 (List 4779 square bore racing carb) and "they" said "it wont work, its way too big for the engine".Proves "they" havent a clue what theyre talking about as the 4779 has slightly smaller bores than the throats of the Honda carbs plus there are distribution problems that the single carbs dont have to deal with.
I wish"they" would leave the old wives tales to the old wives!
