ano po ba mangyayari sa makina ko pag pinagpatuloy ko gamitin ung unleaded or xccs?

The carb jets will "erode" as you use it. So your engine will slowly change from running nice and smooth to running richer and richer.

i dont get this much... im really new in terms here...


by the way... can i just use a toyota 4k engine? will the parts be plentiful and available? and what will be the changes if i shift to surplus diesel engine... will my cost in maintenance be higher if i just use the 4k engine?

thanks in advance

uy hello po newbie kosa_lucena, EX-CON ka ba kosa_lucena? OK pa naman yata makina mo di ba? Why not try to unchoked yung makina mo? Nakakasira kasi pagnkachoke ang makina kc pwepwersahin mo sa gas para tumakbo ang makina mo. Regarding sa 4K parts, madami pa pong parts yan.

Dear Sirs:

The idea that somehow the gas can chemically ERODEs and enlarges the carburetor's jets is a fallacy.

I have used micro drill bits and measuring tools to check and re-jet and can say that what actually happens is that it is more likely that our dirty local gas creates deposits that slowly PLUG the jets over time.

The most likely cause for long term enrichment of the mixture is that something (like a dirty air cleaner) is BLOCKING the supply of air.

Sincerely,

Dusky Lim

Normal running engine = correct ratio of gasoline to air to the cylinders

Richer = more gasoline to air than normal

Lean = less gasoline to air than normal

If you switch to a diesel engine, fuel won't be much of a problem nor maintenance (aside from the usual diesel calibration stuff).

But you will need to replace the transmission to match the diesel engine. And the performance of your vehicle will be slower too.

And yes, potentially black smoke from your exhaust pipe.

now i understand... thank you to all of ur replies... this forum is a great help...

Sir Dusky,
Which creates poorer FC, exhaust pipe with smaller inside diameter than stock or exhaust pipe with larger inside diameter than stock? And also why? I just need to know the effects.
Thanks in advance!

Since the mid 1990's most car manufacturer's have installed very good STOCK exhaust systems on their vehicles.

For all around general performance there is little or no improvement over stock that can be provided by an aftermarket exhaust system.

Of course there are exceptions, and they can only be discussed on a case-to-case basis.

A good example is the excessively restrictive muffler on my Mazda B2500 pickup.

But for 1990's to late model Toyota's, Mitsubishi's, Honda's etc., I defy most local muffler shops to demonstrate a measurable (on the dyno and track) improvement.

If you under-size your exhaust system over stock, it would be like fitting a smaller engine to your vehicle, SAKAL - indeed too much restriction and back-pressure and you will end up with WORSE fuel economy and power.

The same thing will happen (only MUCH, MUCH WORSE for fuel economy and power at the low and mid range) if you OVER-SIZE you exhaust system.

Siguro kung talagang barat ka sa gas, undersizing the pipes and mufflers by 1/4th inch will result in better fuel economy at the expense of top end.
