ive set mine to 2 1/2 turns and RPM should be not more than 900RPM - you should be able to determine by listening on the motor if you dont have the tool.
kinda answering my own question
Your carb is overflowing. Possible causes:I hope some body can help me on this.
My cab is an F6A 3 cylinder/12 valve, carbureted, rear wheel drive only, with no aircon
and no extra accesories.
My problem is this, I'm driving along ortigas extension for approximately 30min. The traffic was moderate and my speed was approx 20-30kph. I stopped for the pedestrian, then slowly moved 2-7meters. All of a sudden at idle, the engine starts to falter then kaput its dead. Started again for 3 times but was successful.
Started to moved the truck slowly to a parking space (buti na lang madaling itulak tong ganitong sasakyan!), when I checked the engine, I immediately noticed dripping gasoline under the carb. I'm an ECE grad, so unfortunately I don't no any of these things. All I did was remove the hose from the air filter, and check for broken fuel lines or anything odd. But I didn't see anything strange. Luckily, a mechanic passed by us and knew what exactly to do.
First, he removed the fuel filter, then drained the fuel from there. Then he started the truck, it started ok but the idle was not smooth. He rev the engine hard (>3000rpm???) for about 5-10min, then he let the engine idle. PRESTO!!!
everything's OK!!! I asked the mechanic whats was wrong and what caused it, he told me that the carb was overflowing with gas and that it needs to be drained, as for the reason he cannot explain it to me.
Now my question is, can somebody tell me the root cause of it? Can it happen again? During sundays, we bring this cab to cavite via SLEX, if it would happen again,
lets say in SLEX, I doubt if there would be a mechanic walking around.
I've tried googling around, and found out that I should clean and/or overhaul the carb. I'd like to here your comments. By the way my current engine is a new one
( Surplus, sariwa pa daw galing japan! ) bought it for 15k php, and its been running for almost 6 months. I'm only using this truck 2-3 times a week, mainit kc eh walang aircon.
Thanks in advance.
Thank you for the replies, but so far it did'nt happened again, even after the typhoon ondoy flood were in this truck is 120% submerged in flood water for 1-1/2 days and only had it running again after 1 month since the flood! ( I feel sorry for those cars with computer boxes though.) Anyway Its still running smoothly today except for the grinding noise every time I step on the clutch, i think its the release bearing I'm not sure but there's no problem on shifting gears.This happened to me last time my carb overflowed.
Take out your float. Shake it- listen for liquid inside. If yes, the float is cracked. Needs to be COMPLETELY DRIED OUT in the sun and then soldered at the crack. Not an easy task since the air inside expands when heated and then contacts when cooling, sucking in air through the crack you just soldered. So you should use a soldering gun- not a torch. And freeze the float before you solder it.
Not sure if there is a leak? Put it in the freezer for 5 minutes. Air will contract inside the float. Take it out and dunk it into a glass of hot water. Air will expand and escape from the crack. If no air bubbles come out, the float is good.
That means your needle valve or seat is leaking or most likely the little adjustment tab on the float needs to be bent to close the needle valve sooner. Easy fix
