u flip the carb upside down u can see the butterfly , two screw that hold it , need impact screw to remove the screw , and to take the shaft out u have to basicly dissassemble the entire carb

You mean, based on the photos which I showed, the throttle butterfly can be reached from below ?
I just want to clean up the throttle butterfly only.

And what is the function of the shaft actually ? Do I need to dismantle the shaft?
Just in case I remove the two screws in red, can I still clean the throttle butterfly without having to take out the entire carburettor ?

yes u can get accsess to the butterfly at the bottom , if u wanted to clean it i dont see the need to disassemble the butterlfy , just a simple turn of the spindle u can clean the entire butterfly

Wow..
Amazing..

Sifu tunjuk ajar..........

hmm our stock carb only 2 knobs/screws to tune? (1 being AFR the other being idling?)

Please advice what are the ways to access to the throttle butterfly valve if I do not remove the 4G13P carburetor from the car ? Thanks ~~

no other way , simple solution , use carburator cleaner to get ur butterfly clean of dirt and carbon

1. Please advice, can we just spray carburetor cleaner into the 4 holes in yellow of the picture?

2. And secondly, in case I still want to attempt to access the throttle butterfly valve without taking out this carburetor from the car, can I just remove the 2 screws in red circle in the picture (and plus one more screw under which cannot be shown on the carburetor view), only 3 screws, then I can remove the front housing, and access to the throttle butterfly valve ?


Attached thumbnail(s)

as per the thread title.. where am I able to find someone to tune my 4G13 carb ?

u spray carburator cleaner with engine running , the cleaner will be suck by the induction along with the dirt , u will get a clean surface , yes u can spray inside the breather hole and air bleed hole , and result to flooded system and make ur engine hard to start

removing the front screw will gain u access to the variable ventury piston housing and the piston itsself and to remove the piston u have to take out a screw on the top , yep it will gain u alittle access to the buterfly , but with the risk of spring falling into the intake manifold , that time it will be fun

anyone can confirm on this?

Thanks for advice ~~ so, it seems it is too complicated to see the throttle butterfly with carburetor still in the car. So will you suggest that I can only spray the carburetor cleanner through the 4 holes when engine is still running ?

And if it is the correct way, then I would only need to remove the circular air filter, which is relatively much simplified work...

yes , the upper is idle jet screw mixture , bottom is main jet screw mixture , to adjust idle to 2k / 3k afr u have to fiddle with the idle jet , beyond that is main jet

argh hand itchy to play with it despite everyone say leave it
