engine stalling

[badkuk]

lately, bumalik ung sakit eng ride ko, i.e. parang binibilaukan ung engine when cold. it would running smoothly, then biglang magstall/surge out of nowhere. this happens when the engine is cold, although it hasn't behaved this way ever.

i made a quick inspection of the engine bay, and found this:



apparently the portion of the air filter directly above the carb jets appear burnt. ano kayang ibig sabihin nito?

i had some overheating problems a few weeks back, pero solved na siya; effect kaya ng pag overheat yung pagkasunog sa filter?

i doubt overheating had anything to do with that...

[badkuk]

aside from the burnt filter, there are some burn marks around the air filter assembly.

is it possible that the a/f mix is getting burnt prematurely, kaya nasunog ung filter? e.g air flows into the throttle body, which sucks in fuel further down along the body, a/f mix gets ignited there before it gets into the cylinders.


what could've ignited it, though? stray sparks? unusually high engine temperature gawa ng pag overheat?

[speedyfix]

heat won't be enough to ignite fuel. you need sparks.
