wilson carberetters in airport west

he is an old guy and seems to know his shit about these things

well worth a try

 

ive used him on all my carbys for my show / modified cars

 

 

my 2 cents anyway

 

good luck

Woz

Yeh mate thats who I'm looking at taking it too, thanks for that(just around the corner from my work). Bit of an update. I put an electric fuel pump(inline 1-4psi for carbies) and it runs alot better. Still coughs some times. so still needs to be tuned. but i can nail it around a corner and it doesnt want to die (as much lol) now.

Ended up ditching the stock carby and got myself a 32.36 i think. with a redline adaptor plate. modded up a bracket for the accelerator cable. needs tuning as it doesnt want to idle below 1200~rpm. think i'll take it to wilson carbies once its back on the road for a tune.

It probably needs the idle circuit cleaning out, the same as your stock carb did.

 

If they sit around and dry out the tiny chambers and drillings get blocked with resin and dirt, and if it gets free it often ends up blocking the jet.

 

The idle jet runs the car up to about 2000rpm when it finally hands over to the main jet, so idle jet problems make it lean for all that initial acceleration.

 

Let us know what jets you end up using in the Weber, there's a lot of guys got them on here.

the idles are too rich! i hadd the same problem with my 28/36.

 

there was a 60/70 idle in it and the idle would stay around the 2 grand mark.

 

now its currently got 45/50 and its down to 1100. (needs 40/45)

 

if you want me to have a play around with it pm me

ok . so the cars booked in for next tuesday to go to Wilson Carbies. Just so i can get the correct gear in before then a good base to start with would be?

 

Main Jets

pri sec

135 140 <- ive got 100, 135, 140, 145 to play with)

 

Air correctors

pri sec

170 190 <- ive got 170, 160, 135, 100)

 

Idle

pri sec

45 50 <- this looks good enough from what ive read.

 

Is there any other shops in the west/north that sell jets (other than Thornbury carbies or is that as close as i can get)(don't want to pay another $8 in shipping for a $7 jet from weber) Wilson didnt know if they had them in stock...

 

As i need to buy another air corrector (190) for my setup i think..

 

Evan I'm looking at you lol...
