I am going to try two webers on my son,s TP auto on the weekend.

I have a 32/36 DGV and a Ford 34 ADM .

I have to order the jets, as I,m pretty sure that the standard ones in it are too big.
As I,m in a rural area I can,t just pop down to a local parts place.

What,s the recommended sizes , for a stock motor?


I was thinking of 120 Prim fuel, 160 sec fuel, 160 prim air 180 sec air, 45 / 50 for idle jets.

Sound like a good starting point?

y dont u get an A/F metre and test it? get an oxygen sensor hole welded in ($20 at any exhaust place) and get the A/F metre. its upwards of $200 i think but its there and u can use it to tune the car anytime u want. all u need then is a cheap as laptop, d/l the software and u have ur very own tuning tool.

i have a single weber on my car and my primary fuel i think is 135 and secondary fuel is 220. gives me a perfect air fuel ratio wen cruising and on WOT. but, i do have other mods so it would differ slightly to a stock car. something to think about anyway

I,m making a mixture meter right now as I type , , just etching the PCB, it,s the one from performance electronics, it,s good around stoichiometric, so should be ok .

I just needed some idea where to start with jets , as it takes a few days to get the jets in.
I,m a few hundred km,s from a major town.

I,ve got the old O2 sensor from the commodore , which should be ok, single wire job.

Damn I just noticed I don,t have an LM358 IC in my parts bin, Dick Smith is 300K away :)

im running the same, seems to run pretty well, the secondary of 220 might be slightly rich though, ive gotta dyno tune it once ive run this engine in. but wouldnt be far off with them
i dont know if the mechanic who did the engine transplant changed my idle jets but i found that with my old engine 55/60 idle jets worked pretty well. 60/70 made it run rough unless i turned the screw out heaps.

well my A/F ratio with those jets in i think is about 14/15 wen cruising (just on primaries) and about 13/14 on WOT. which is pretty good. it could go alittle higher wen cruising... maybe a 15/16 or so, but just for fuel economy issues.

/me waits for a phone call from the old man to drive 300km back home with the part lol

Would 45/50 idle jets be too small for a 34 ADM on a stock Magna TP? Think we should just stick with 50/55? or 55/60? And would 135 Primary fuel and 220 Secondary fuel work well in my situation?

It,s ok , I,m using a TL072 op amp, pin pin for substitute.
