Thanks bro!

Now continue completing exhaust system upgrades after got enough budget.
My current rusted muffler got holes....added 1 big hole i accidentally poked during extractor upgrades. now sound like cheap straight flow oredi. haha....
I have 1 minor issue which is stalling/jerking 1-2 seconds after ignition off. Sometimes it occurs, sometimes not. After reading through previous owners experiences, it's between rich mixture or solenoid kong.
So...wanna try carb tune first. The back of carb is the air mixture right? Is it turning clockwise or anticlockwise for leaner mixture?
Due to sometimes occur only, do you think the solenoid kong or not?

Solenoid kong will judder EVERYTIME u switch off the engine. It's likely to be overflow IMO. Before jumping into "tuning" your carb, it's advisable to give it a carb cleaning process. I solved mine with a bottle of electronic contact cleaner. I know there are specific carb cleaner spray out there, but I had bad experience with the carb cleaner spray which I wouldn't like to share it publicly, hence Alcohol base solution is my next best bet. The usual spray and vacuumize of throttlebody several rounds at high revs. Once done, change sparkplugs. Ever since, never happen to me anymore

On the worst case scenario, it could be the solenoid START to kong, where the shaft weren't able to extend fully when engine's off. Which you have a very good chance in reviving it with electronic contact cleaner spray. It could be stains on the shaft that prevent it from thrusting but that's all. Tuning carburetor is the last thing I do, and I only trust CO reading where I need to send my car to a magician who has a machine/dyno machine to do so.

Others who always claim which sifu very powderful, by listen to the engine sound, see the RPM, feel the engine vibration, smell the exhaust fume ady can tell whether it's rich/lean is a big question mark to me. On a very bad situation where a petrol car start to emit black smoke, that ofcourse even a blind person also can tell it's running rich. But hey, how do you know it's not because of lean AIR that causes the RICH on FUEL?

My carb tuning never been kacauing me other than, overhaul job, change from 4toto back to stock - whilst other surroundings been upgraded such as valve springs, lifts, and also weird setup of exhaust system

Other than the mentioned, the carb has been always running on the same setting after got out from the O2 reader and or dyno machine

Do you get what I mean?
