not satisfied with Speed

AE92 4A-F (Small body)

di naman sya mabagal pero napapansin ko na medyo mahina sya in terms of RPM. Nag-try ako mag-Rev ng naka Neutral at hirap(Or medyo di ganun kabilis paabutin) sya paabutin ng 4K. so far ang pinaka mataas kong naabot habang umaarangkada is 3K (RPM - Primera) tapos kapag segunda at tersera medyo matagal na paabutin ng 3k. Samantalang nakikita ko sa mga Video, kayang kaya isagad hanggang 8k(Neutral - tapos Rev lang).

Ano ba ung mga dapat kong i-consider or dapat i-check?

tune up muna. then i-assess mo.

usually sa tune up:

change oil
change spark plugs (right specs)
change high tension wires kung luma na (e.g. cracked)
change air filter
i-patiming ang makina (using timing light kung pwede)

check the distributor: change the cover at yung rotor (mura lang ito)

kung kaya pa sa budget, overhaul ang carb (mga 1.5K ata sa Metro Manila)

posible din kaya ito for toyota 2e engine?

Sounds like carb overhaul and ignition advance issues

-Yung Air Filter po ba ung nasa carb?
-Okay ba ung Bosch Spark Plugs? and, ano ung specs ng Spark Plug ng 4A-F na makina?
-Magkano po ung Rotor at Cover?

Maraming Salamat!

sorry to confuse you sir..

Just curious dahil 3k rpm lang din inaabot ng engine ko.

kahit newly top overhaul, change oil, replace High tension wires and spark plugs yung engine ko.

An engine of an AE-92 should be free revving up to the redline without any signs of losing power...

The 2 primary suspects are: fuel delivery or electricals. I suggest you check the systems one at a time...

Considering the age of this venerable engine, the high tension leads could show signs of wear and this could lead to the "kinakapos ng hangin" phenomenon. The HT leads can have cracks and could lead to less delivery of current to the sparkplug. To test if your HT leads are not shorting, open your bonnet and run the engine. Make sure you do this at night with a minimum of light around. If you see blue sparks coming out of the HT leads then there's one problem.

As for fuel delivery, look into the fuel filter system. There are usually 2 fuel filters so make sure you look into both. If the filters are good then, as the previous posters have mentioned, a carb cleaning/overhaul is in order.

The 4A-F engine was one of the first engines in the Philippines to have electronic ignitionI seriously doubt if there's something wrong with the timing. Unless the mechanics misaligned the camshaft gears ever so slightly, that will be the only time it will have timing issues.

Hope this helps.......
