hello all.

well striped my carbs again and reset the floats again sadly when i drove it it fell flat on its face still 8-(

soooo i decided to try a different aproach i found the original alfa 115 main jets out took myself a 1.5mm drill and well you can guess the rest .

it is driving a hell of a lot better in fact its frightning 8-)

my head temps are down 50 o F and this is good news .

ive done a big jump here from a 135 main to a drilled 150 (bigger id imagine by default ) i now want to try a 140 / 145 for the perfect setting.

as much as i didnt like drilling out jets doing it and fitting a bigger main has saved me a lot of pain.

here is how they have ended up.

40 dells (ex alfa)
35mm vent (custom bored by local tame engineer type)
150 main (drilled sadly by my own wavy hand)
180 air (as per usuall)
55 idle (out 1 1/2 turns running 900rpm)
5mm- 17mm float
35 pump (still on alfa setting needs checking)
cold start wired shut
on 21/2 in tall manifolds
fuel pressure (lazy man still not checked left to right carb flow!!!)


and does it rev o yea need ther weather to get better so i can get onto the autobahn and open it up a bit

the locals really dont expect to be overtaken by an old typ 3 with english number plates on it but i cant help myself and it just seemed to happen loads today.

well worth a conversion to a typ 4 engine.

my gearbox is going to die i think!!!
