    650cfm QFT Carb Tuning / 383 / 727

    Hi guys, I did some tests, went from 62 to 64 on primary jets, from 42 to 37 on primary pump nozzle and changed from pink to green cam. Results are much better! I even gave it a go with the blue cam that I think I will stick with. Going from 0 to WOT as never been that fluent since I own the...

    650cfm QFT Carb Tuning / 383 / 727

    Hi Mattax, Many thanks for this great answer. I may not be that far from a good solution. I think that without knowing I've been trying to compensate a lean condition setting bigger pump nozzle whereas it may come from the pump shot cam. I'm going to go from 62 to 64 on primary jets and try to...

    650cfm QFT Carb Tuning / 383 / 727

    Hi Gents, I am looking for a set up for my QFT 650cfm double pumper carb as I can't find help over here in France. I would need a configuration of jets, squirters and power valve as a basis I could adjust afterward. I did some tests but I get lost with my AFR readings. When the carb was stock...

    [WANTED] Bay engine part of driver fender Plym Duster 70

    Hi guys, I'm looking for the inner part of a driver side fender. I can't buy a full fender as it would be costly to get it sent to France where I live. This way I could rework my actual fender to have something clean before painting. Car is a 1970 Plymouth Duster Cheers! Nico

    Door end seal, pillar seals and lock seals...

    Hi Gents, Pretty hard for me to make the difference between these seals... I'm I right saying that "Pillar seals", "U-jamb" and "lock seal" reffers to the same part? YearOne don't have these seals for my application (1970 plymouth duster) they say. Do you know if I'm supposed to have those on...

    Main jet tuning... ...in France

    Ok... And what's the process I should follow using the AFR gauge to find the good PV?

    Main jet tuning... ...in France

    I did some tests with a 4.5 PV I found. First feeling : I get "holes" in acceleration when applying load so I guess 4.5 is too small. Keeping the 60 main jets I get an AFR around 15.6 when cruising at 3000rpm in 3rd gear. with 68 main jets I get an AFR around 12.0 when cruising at 3000rpm in...

    Hi Yellow rose, thank you for your help :) I'll let you know as soon as I'm sure I need them. @AJ : I checked the vacuum at idle, transmission in D : it's between 12 and 13 with vacuum advance plugged in. I guess I should keep the 6.5 PV? Nico

    Main jet tuning... ...in France

    Hi Guys, I'm now dealing with the carburation tuning on my 1970 Plymouth duster. I first ordered a full set of main jets from quick fuel ($94) but it turned out I need smaller primary jets than the 68 stock ones (kit range is 75 to 110) so I ordered 57, 58, 59 and 60 (regarding the AFR gauge...

    Battery ground wire and hot wire section

    Well, to be fair that's what I was thinking about, but if it's better to have two wires of the same size, I guess I'll go for a bigger one. Update on some tests I did with a big /00 positive wire and a smaller section negative one : when car is warm she struggles to start, I can see a huge...

    Battery ground wire and hot wire section

    Hi, First I bought a complete kit with too small section wires.So I just bought a new bigger /00 red wire and I wonder if I have to do the same with my negative wire. But I guess I have the answer now ;)

    Hi guys, Thank you for your replies. The kit I bought came with a 2 gage red wire and a 3 gage black wire both 14 feet long. I had difficulties trying to crank up the engine and wires were hot so I guess I have to replace them. I will go for a 2 times bigger red wire but I wonder if I have to...
