![]() Less throttle needed for highway cruise :1 occasionally 14:1 very little backfire (if any) at deceleration 15-18:1 but smooth decel. Gas mileage 24.4-10.08%= 21.94 actual mpg (my speedometer is a little on the high side).ĥ7° dew point Second quickest set up to redline. Higher dew point 66° leaner readings in the 14-15:1 at idle at sea level. Side note engine temperature at shut off in garage 195° 95° ambient. 12.5:1 highway acceleration up steep grades, 13-14.8 low throttle uphill highway.Ħ/13 very close to the same as above 68° 40% humidity 43° dew point, car ran very smoothly.Ħ/25 93°ambient dew point 55° AFR about the same running mostly between 11.5:1 to 14.5:1 between 12.2:1 and 13.5:1 90% of the time. Smoothest deceleration with almost no sputtering (clean) Wideband readings about the same as Change 19, dew point 58° elevation 0-2000 ft.Įvening 1k to 2k ft. Very good! As quick as any set up to redline (still feeling power in yellow line to redline). Timing and Distributor advance will also be a performance factor. I am not the author, but directing you to his information. This is ballpark Weber Jetting for San Diego, CA - Sea Level to 2,000 ft. Thanking in advance those that have the knowledge and for sharing it with me. I only have to wait until the unbearable heat lets up here in the very Southern part of South Carolina which should be coming soon. I have also read a lot about that procedure and stand ready to move forward to complete that project as well. I want to make sure the jetting and carb tuning is spot on prior to moving forward to my last major project under the hood and that will be adjusting the valves. So who out there has a 2.0 similar to mine that could give me some ideas on what my jetting should be. I am pretty confident that when I purchased the new Weber from Pierce that I failed to mention that my request for a new carb was nothing more than a stock 1.9 GT - I have learned a lot since then. I have not taken the new Spain made Weber apart yet but assume the jetting would be similar. The GT's new engine, as of today, has a total of 2400 miles on the odometer after my 60 mile drive today, and the Spain made carb on the car would have a little less mileage than that, perhaps 1000 miles less.Įverything on the used carb appeared to be in good working order and had the following Jets: However one of the emulsion Tube caps was clogged.Perhaps that was my problem with this carb from the time I installed it 20 years ago?Ĭurrent Jets in the used/and or rebuilt Italian Weber: ![]() Anyway the used Weber, made in Italy, never seemed to run right so 10 years ago I purchase a new one, made in Spain, from Pierce Manifolds. Without these videos I would never have tried it. there is both a tear down video and a rebuild video, specifically for the 32-36 DGA series. ![]()
