Hi!
Currently building a slightly modified 2 liter 131 fast road engine with the following specs:
131 block 10.5:1 comp
130 tc head nicely ported etc with bronce guides
124 std exhaust cam driving elevated distributor
Inlet cam: Colombo & Bariani 272`/ 10.3 lift/ 1.8 Ltdc
124 1800 SC inlet manifold ported slightly
124 1800 cast iron exhaust manifold ported (4-2-1 version) - 2" exhaust
Current carb and settings:
"New" 30 year old Weber ADFA 34 from 131 with emission controls and a lots of hoses everywhere (Sweden...)
Venturies now taken from 24/26mm to 26/28mm - did not dare to take it out further due to wall thickness...
Jetting as is:
primary:
emulsion tube: F 84
main: 120
air corr: 165
secondary:
emulsion tube: F 5
main: 125
air corr: 190
Plan is to eliminate/block as many ports as possible:-), and try to do a decent jetting of the carb - taking into account the bigger venturies, and increased airflow through the engine.
Any suggestions greatly appreciated!
Best regards
Remi Lovhoiden
