Carb jet suggestions for my car, anybody?
Ok, last night I took apart the both carburetor (Weber) rows and what I found was, goo. Yes, goo everywhere, every jet and other things weren covered in oxides and some were clogged very badly.
The carbs are clean now, but I would like to know the right jet sizes for my engine. My car has 2.4L T engine and its a -71. The carburetors are Weber Tipo 4010XXXX something. What sizes to use for jets, venturi and other things that are in the carb (that affect performance and fuel consumption)? |

I wouln't say I "know", but in my 2.4T (since
replaced), as I recall: 130 main jets 60 idle jets f26 (or was it f27?) tubes 30 mm venturi can't,for the life of me,remember the air correction jets, maybe 140s This was a tad rich. Ran decent, but keeping the plugs clean was problematic. I found excessive carbon in the combustion chambers when I tore it down. JPIII |

maybe 32 venturis with a 2.4. f26 tubes were stock and work ok but i've had good luck with f3. 140 airs would run the engine pretty rich on top end. maybe try 170 and step down to 160 if top end lacks power.

Mine has these:
??? main jets 45 DRILLED by po =( idle jets f26 tubes 27 mm venturi 170 air correction jets Last night the car was almost got on fire. First of all, after the cleanup of the carbs the car is now backfiring all the time. Also when I gave some gas to it, cylinder number 3 backfired so much that it threw out these 20cm high flames to the engine compartment. After that I turned off the engine. And what did I hear? Tsss! Tsss! Tsss! Checked under the car and I saw gasoline dripping all over the hot exhaust! No the carbs were not flooding, checked that. Ah, the fuel hose after the fuel filter had gone bad. No wonder I always smelled gasoline inside the car. Well lucky me it did not get on fire, because I had no fire extinguisher nearby. I just went couple meters backwards and started smoking tobacco. Then suddenly WHOOSH! Naah, just kidding, the exhaust cooled and the gas stopped dripping also. Today I am going to buy new hoses, also removing the metal "gas divider" from the engine compartment and replacing it with this rubber fuel hose that is reinforced with metal. All I can say is "Phew" and remove the sweat from my forehead. //Zen |
