[theorekz]

but master cookie, is it ok tht the screw was turned differently??? Cause one is turned horizontally while the other senget a bit upwards... And i ask something stupid can? Is it possible to modify the K&N filter for 12v aisan carb to fit into DCNF?

advan30, thts a really nice deal.. semua datang only Rm450.. too bad i already bought 1 for myself.. 36 DCNF means venturi smaller ar?

another thing, weber dcnf has the function like aisan carb where if u cold start the car, it will automatically rev the car until certain temp then it stops?

cheers
:D

this is a progressive carb..
at a certain rpm or suddent throttle open then only the second butterfly will open

this is to ensure, that you have good driveability and fuel consumption with the advantage of having twin barrels and only used when the driver indicates it..

from what car?

The two yellow screws is ur jets..

the aux venturi should be tight not longgar

the control ur idle, that all it does...

photos are a bit blur and out of focus..

 

[narx]

can i know what is the 2 yellow drawing there?? What screw / jet is it?? And the placing is shown as above... One is placed horizontally, while the another one is diagonally....

o.. ya btw, is it necessary to change the spark plugs into better 1 like iridium or platinum to provide bigger sparks? Thts wht my mech told me, he says it is the best to upgrade spark cause i have changed to dcnf...

happy new year.. :D


thx hatta for the pic
:D

spark plugs? eerr no need..unless ur changing the entire ignition system..
but this what i knowler..
