WET.K30 Posted February 15, 2011 Report Posted February 15, 2011 hey evrionee I'm in the middle of putting twin 40mm dcoe webbers on my ke30, 4kc can anyone please tell me what they done with the break booster hose that goes on the manifold and the vacume advance hose from the dizzy advice would be greatly appreciated JOSH :) Quote
altezzaclub Posted February 15, 2011 Report Posted February 15, 2011 If you're really really keen you can drill & thread into each arm of the manifold and run a line to the brake m'cyl that goes into each one through T-pieces. I did that once, but the next time I just ran it into number 4, there's not that much air goes in through the brake booster line. The vac advance needs to be fitted according to how Toyota did it. If it works off manifold vacuum just drill & tap it into number one, or anywhere in the Weber manifold. If it needs ported vacuum then you will have to put it into the actual carb if Webers run a port for that. If you don't know the difference between manifold and ported vacuums, its time for an hour on Google.. Read the jet sizes and post them up somewhere for us... I assume it has 30mm chokes, yes? Quote
WET.K30 Posted February 15, 2011 Author Report Posted February 15, 2011 I'm runing no choke, 27 mm venturies :) ighty ill try that thanks dude Quote
altezzaclub Posted February 15, 2011 Report Posted February 15, 2011 (edited) Great- chokes are used as the same term as venturis, although 'venturi' is the correct word. The starting cable 'choke' you won't need as Webers pump so much fuel in when you boot them the starting problems are always with flooding! You have four 27mm venturis, compared to the usual 32/36 downdraught Weber with one 26mm and one 27mm... so it should fly at high revs! If you pop a top off you can extract a jet set and read off the air jet size, the emulsion tube number and the main jet size. Those 3 and the idle jet will form the basis of tuning them to suit your motor. They should be something like: main 110/air 175/emulsion F16/idle 50F11. and the idle should set smoothly between 1.5 and 2.5 turns out on each throat, otherwise the idle jet is the wrong size. Ah- it also seems the DCOE never fitted ported vacuum, so if your dizzy runs on that then you won't have vac advance working. Edited February 15, 2011 by altezzaclub Quote
