My new 22r has a 32/36 weber and I followed the weber set up to a tee. It had a little flat spot just before secondary and the mixture screw ended up a 3 turns with 55- 50 idle jets. I bumped up to 60-55 jets and it definitely better but still fill a little anemic at 1/2 to 2/3 throttle just before secondaries. Secondaries are great. Mixture screw is a about 2 1/2 turns. Tried 65-60 jets but I had difficulty with the mixture screw and had almost no room to play. Seems like it was at about 1 3/4 turns but the truck drove not well. Just did not feel as good as the 60-55 set up I have now. Any Ideas??thanksmark
I can't seem to get mine right either Sir. Idles great but weak on the primaries with a HUGE stumble when you open the secondaries. I'm only getting 12-13 MPG to and this is with a brand new ATK long block. My wife gets 18-21 MPG in her 86 Runner and the motor has 181,000 miles on it! Her runner will just pull away from my 82 truck on the highway as well. I'll be watching your thread to see if you get any good advice sir, good luck!Nate
and what jets (idle, fuel, and air) are you running??
QuoteQuotemy idle jets are 60pri and 55secmy fuel jets are 135pri and 130secmy air jets are 165pri and 160secfeels abit lean first half throttle but I would not really call it a flat spotengine has an RV torque cam, oversized valves and springsand 2 inch exhaustthose fuel jets are WAY too smallthe air jets are also small but not as far offi want you to start here idle jets 55p and 55sfuel 140p and 150 sair 165p 180 secokI will go with your recommendation
