Crashtd420 Posted June 10, 2019 Report Share Posted June 10, 2019 You can probably leave the air correctors alone..... usually they effect high speed operation... mostly when going wot... So if you were going lean at wot and high on the rpms you would want a smaller air corrector... How did the f2 emulsion tubes changes things? Can you possibly describe? I went from f11 to f8 tubes and it tightened up my high rpm readings.... Once I get on the main circuit I stay pretty stable.... i had thought about trying the f2 also.... 1 Quote Link to comment
alexg89 Posted June 10, 2019 Author Report Share Posted June 10, 2019 Its kinda hard to explain to be honest.. it just feels smoother when like backing out of my driveway and leaving .. before id put it in gear and drive away and it would hesitate and buck unitl it got past the rough spot and now it dosnt really do that.. i can feel a slight hiccup but nothing like it was It was still super rich so i stuck the smaller idle jets back in and it messed it all up so im gonna stick the 65s back in and see what i can make happen I think with a larger air corrector tho it may help.. Not sure but im gonna buy the main and idle jet kit i think and start messing with them Quote Link to comment

All you can do is experiment once your close.... at least it sounds like it's more driveable.... It drives me crazy because I'll make a change i think will help and it will but then it throws something else off..... 1 Quote Link to comment
alexg89 Posted June 10, 2019 Author Report Share Posted June 10, 2019 On my lunch i put the 65s back in and put the idle circuits back to where i had them .. its deff more driver friendly now and dosnt buck while going down the road between 30-45..i can actually enjoy it When i go to a nice long straight away i floored it 1st through top of 3rd and the wideband was a 9 the entire time except between shifts when i let off so i think the larger air corrector may help with that Not sure though casuse well i dont know what im doing lol Quote Link to comment

Not sure but im gonna buy the main and idle jet kit i think and start messing with them Does it get better or worse when you lean into the throttle? Does it get better or worse if you stomp on the gas pedal? One easy trick is to gradually pull on the choke (when things are acting up). If it starts to run worse when the choke is pulled, then you know you don't need more fuel. It is very hard to know the difference between how all the various jets, nozzles, pumps and venturis affect the driving. Sometimes an adjustment to the accelerator pump or pump nozzle fixes what seems like a jetting issue. Have you been paying attention to how the spark plugs look? Quote Link to comment

I have not to be honest.. i put the new plugs in weeks ago and have just been trying to get it to run i have a new set on the bench i need to put in and start over again with watching the colors of them Quote Link to comment

The air corrector will only correct the top end but the main will reduce the whole circuit ( only taking about main/air corrector) I still think you need to lean out that main jet.... If it started off good as you got on the main jets and then it went rich then I would agree go bigger on the air corrector.... you may still need to but I still think you should go after the main first.... What are you currently running for a main and air corrector? Quote Link to comment

Crashtd420 Posted June 10, 2019 Report Share Posted June 10, 2019 I'm actually about 2 3/4 turns out on my air/fuel screw....I am running a leaner idle and main jet now and I feel I'm getting closer..... I was surprised how much the idle jet didnt effect my idle as much as it effected my cruising on part throttle, which is what its supposed to do I guess..... I did some plug checks and it seemed to follow what my air/fuel was telling me so you should be ok.... but it cant hurt to pull them and check..... Ideally while out for a cruise get a steady reading on the gauge, kill the motor and see if the plugs agree .. Quote Link to comment

And usually I've seen a larger separation between mains and air correctors.... about 50.... Currently I have 125 mains and a 180 air corrector.... Quote Link to comment

You are definitely rich all over..... I know messing with the air fuel makes it stubble , but maybe you need to lean it out then bring the idle up some..... I dont use a choke but I have to keep the idle up a bit during start up or I'll be up around 15 to 16..... once its warmed up it drops and hangs around 12.5 to 13... Quote Link to comment

docbainey Posted June 10, 2019 Report Share Posted June 10, 2019 (edited) Hey, I'm not pimpim this, but, it puts all into perspective. Yeah, your AC jets are probably wrong. That probably jacks everything else up. Just chasing your tale. https://www.piercemanifolds.com/product_p/98.1517.05.htm Best money I ever spent to save me money!

alexg89 Posted June 11, 2019 Author Report Share Posted June 11, 2019 Went home on lunch and got the truck heres a little video of the super rich, slow, not exciting, blubbery pull Quote Link to comment
datzenmike Posted June 12, 2019 Report Share Posted June 12, 2019 You know.... 9 may be as low as the gauge can measure. Probably in the 8s. Quote Link to comment
alexg89 Posted June 12, 2019 Author Report Share Posted June 12, 2019 Yah i would agree with you Quote Link to comment

I may have to try that .. i ordered the Mains and air correctors last night so im gonna put them in and then get some plugs.. I know its rich for sure, its not as responsive as it was before Quote Link to comment
alexg89 Posted June 13, 2019 Author Report Share Posted June 13, 2019 (edited) so i pulled the number 2 plug last night that the wide band is on and im kinda confused How is this thing not pitch black and what is happening lol Edited June 13, 2019 by alexg89 1 Quote Link to comment
Crashtd420 Posted June 13, 2019 Report Share Posted June 13, 2019 Not sure what to say there...... Did you run the motor just before pulling it? Maybe do a recalibration on your gauge.... with mine I had to expose the o2 sensor to open air and power it up to calibrate then reinstall into exhaust.... Quote Link to comment
alexg89 Posted June 13, 2019 Author Report Share Posted June 13, 2019 No it had been sitting all day and i just decided to pull it out .. ill try a re calibration on it and see what the scoop is .. but it dosnt explain why its so sluggish unless the timing is playing a factor finally .. I still have the jets coming and should be here Saturday so im deff gonna mess around with it Quote Link to comment
