Hello from Cyprus. Ok guys I really need your help re-jetting my Weber 32/36. I' ve searched the entire internet and can't seem to find a straight answer. I have a stock 4K engine on a KP36 Ute. Bought the engine brand new from an old part store, doesn't even have serial numbers on it :) These are the following installed so far: Stock 4k motor Weber 32/36 manual choke 4 X NGK BPR5EY Spark Plugs AccuSpark Electronic Ignition AccuSpark 12V Red Coil Custom Extractors 4K Heavy Duty Water Pump 71 Degrees Celsius Low Temp Stainless Racing Thermostat Racing Mechanical Fuel Pump I recently followed the advice from an old post in another site and tried re-jetting it with the following: primary main jet = 125, aircorrector = 180, emulsion tube = F50, idle jet = 55 secondary main = 130, aircorrector = 195, emulsion tube = F6, idle jet = 50 The car drives like SHIT. This is my everyday car. I start it up at 5am and needs 10min to warm up. I pull the choke and it shuts off. As soon as I start driving it just hesitates. It's driving me mad. I even bought an electronic distributor and brand new coil and sparks. What are the best Jet Sizes I can use? You are my last hope.
Hello, I posted this in my rides thread but ill put it here too, I have recently put a weber 32/36 on my 4k and fitted extractors at the same time. The carby came off a 18RG? i think. I can't get it to idle stable. It seems to be very rich at idle. Have attempted to tune according to basic settings and will continue to surge at idle and when backed off from accelerating will drop and nearly stall. I have checked: 1/ Ignition timing - 10BTDC at idle and advance is working on acceleration. 2/ used starter spray to check for air leaks, couldnt find any. when i replaced it i replaced all gaskets including manifold gasket and used aviation sealant on carby and adaptor plate gaskets 3/ Have checekd jets, it has Primary/Secondary 140/135 mains 160/175 Air 50/55 Idle 4/ it idle very well before carby swap It has an electric fuel pump fitted which worked on standard carby with no problems My questionsn are 1/ Shoud the air jets be larger on the secondary instead of mains? 2/ Do i need a fuel return line, at the moment i have blocked it and i suspect this may be a problem? The red arrow is fuel in The green arrow is blocked fuel return the blue arrow is the vac adavance hose 3/ any other suggestions? Please see youtube video of what it is doing,
