E85 might need more fuel than no jet at all. . Pretty sure I recall seeing a post where someone modded a Gemini carby forE85 and basically had no jet in the secondary. I actually think a Gemini carby would be better for this engine. ..vacuum secondary with a very small primary. And electric choke. Would need mods to install though

yeah i have the Renault carby, which ive been running. thats the one with the 125s. I also have 4 other twin choke carbys. 3 webers, which consist of a rebuilt 32/36, a 32/36 in bits, an actual 1300GT carby (i think) and a Holley licensed copy of a weber 1300GT carby. the last two i mentioned have been sitting for F knows how long. the holley carby, is extremely rare. i asked weber about them, and he said he hasnt seen one in over 20 years. -
Me thinks 140 on the primary when it should be 125 is still too fat. That's like too much jet on a Holley by 6 sizes. Small engine too, so is amplified. Do you have any other carbies to raid for their jets? Can you swap in a bigger air correction jet to compensate?

haha imagine an engine that would need so much fuel it would run without main jets haha. I think ill try changing to the 125s tomorrow and go from there. ill check base timing, see if i can squeeze some more out of it. the engine runs cold, so maybe advancing it more might get it running at normal temp haha
-
yeah i have 140 primary and 150 secondary in the same carby on a mild 2 litre in the gemini. so i suspect they'd be way rich.. not as rich as a jet removed though..
-
yeah, i should add i also had to put the choke back together. the first time i pulled the choke lever the choke setup sprung apart. the retaining pin dissappeared lol. so ill be emailing weber australia with pics and just giving them a heads up. yes you're correct. so yes its a big jump. Im hoping i can get away with dropping the main jet size down to the 125s, and the rest of the jets and sizes are close enough for the car to run happier. at the end of the day, the other jets are pretty close to what ive been running.
-
That's a shocka.. and 140 refers to a jet size of 1.4mm? That's a huge jump from 1.25. It's the equivalent of going from 62 to 78 on a Holley if my rough calcs are right

So I bit the bullet and decided to replace the carby at last with a brand new 32/36 DGV. interesting to see the clean and dirty sides of the intake all installed, using stock full length cable, with some special engineering on the big washers on either side of the throttle bracket. stock rocker cover back on. because this a factory manual choke carby, it works 10000000000000 x better than my converted manual choke carby, that used to be auto choke. I got it running and driving, but couldnt use full throttle. would completely bog down and just die under load. So tonight, i pulled the top off carby to see why.... and this is what i found. yep, brand new weber, which i picked up myself from weber performance, and this is what i find. secondary main jet out, primary main jet was lose, just sitting in.
put them back, and got the car going and driving way way better, but still not 100%. im guessing its over jetted for the 1300. this is the jetting comparison. should make sense hopefully. the Renault Carby is what ive been running. -

I had these noises from under my AU XR 6, The mechanic said link pins were gone, I bought some springs and monroe shocks and a 28 mm sway bar 2 new link pinks, It sits a few MM,s lower and handles better ..However the noises are still there...the only thing the MECHANIC pointed out to me was the rotors were slightly warped, could that be where the noise/s are coming from....he did not say any thing about the Ball joints..?
