Pinto Only Likes Accelerating

[keith kelly]

hi,

i have a pinto with twin weber 45's on that everyone keeps telling me to take off (i never give up). she runs find if you put your foot down but does not like plodding along in traffic. she pops and sounds a little rough. before i start palying is this likely to be the timing as i am almost certain the carbs now setup right? she runs fine at idle and if you apply throttle at standstill. and as i said she runs fine accelerating.

 

the timing is set to 12deg

the webers are as follows

 

all fully sincronised with same air to each

choke 36mm

main jet 145

air corctor 180

emultion tube f16

idle jet 60f9

 

any suggestions would be helpfull

 

regards

keith

I had Twin 40's on my xflow 1600 Sylva Striker and I have to say the best thing I ever did was put them on ebay.

 

(Stand by for friendly abuse from Weber fans!!!)

 

Car ran so much better in all situations on a twin choke Weber downdraft.

 

Sorry, not much practical to offer other than I had nothing but bother with my twin webers

Hi Keith,

 

You don't say what cam you are running. 12 degrees is a bit high for a standard cam but ok for hi lift one. Sounds like your carbs are not running the correct mixture on part throttle. What fuel pump are you using? If its an electric one are you using a fuel pressure regulator?

 

The only way to set up twin weber carbs is on a rolling road. There are way too many factors to take into account with changing jets by trial and error and the only real way to sort it out is when the car is under load on the rollers.

 

The only rolling road I've used is Bogg Bros and Dave knows his stuff. Quite reasonable but quite far for us Leicester hoodies.
