4k engine valve clearance, idle speed, ignition timing

[exoskeleton]

mga idol baka meron kayo ng manual ng 4k engine, baka pwede po pa post ng mga value ng mga sumusunod para maset ko sa tama..

1) ignition timing = degrees BTDC in relation to respective RPM

2) valve clearance = INTAKE & EXHAUST

3) stock jettings = pilot/slow jet, primary & secondary

1) ignition timing = 52 degrees BTDC

i doubt any engine will run at this ignition timing, not even the computer controlled ignition. some ignition system go as high as 36 degrees at higher revs. when you check igniton timing, it is set at idle speed with electronic spark advance disabled or both the vacuum and centrifugal advance disabled.please check again.

you might have been talking about ignition points dwell angle. 360 degrees divided by number of cylinders multiplied by 60% +/- 2 degrees

ah un nga sir heheh

try 7 degrees BTDC first and test drive, if memory serves me right it is between 7 to 9 degrees BTDC at idle with vacuum and centrifugal advancers disabled

in this website, the factory ignition timing is at 8 degrees BTDC
