You won't find anyone who can do this without trial and error. I have kept a carb'd Honda before, and I know the pain.

My go to guy was Altaf at phase 2. I can PM you his number. He's an older gentleman and does a better job than anyone else that I showed my car to.

[pwuser157216306436]

Thanks for your reply. I would be grateful if you could share his contact. I also had a Civic EF 91 before and it was ruined by the mechanics, which I eventually ended up selling after spending hefty amount on restoration. It was giving me around 4km/l average. I don't want to repeat that episode with my accord since it's gem of a car.

This car is nothing too special, any mechanic who can work on a later model carb city or civic can work it, its basically the same carburettor just slightly larger.

The few differences are the timing marks, the valve clearances etc.

I dont know of any mechanic personally now as its been a very long time since I left Pk.

[pwuser153796752163]

No one works on carburetors anymore, only a specialized mechanic would do that, i.e. someone who works on older Euro or American cars.

[Xulfiqar]

You definitely do not want a stromberg or carter carburetor mechanic working on this.

Those guys are completely insane, this carburettor is very simple, imagine it like a slightly weird shaped and larger mehran carburetor.

[pwuser153796752163]

Yeah, my point was; no mechanic wants to work on carburetors anymore, it's easier for them to swap sensors or "assemblies". Makes them more money too. A friend can rebuild a carburetor in a day, but to make him do that is almost impossible.

[Xulfiqar]

If no one wants to work on it anymore then the only hope of getting these running good again is full 100% DIY.

[pwuser157216306436]

@Xulfiqar bhai my mechanic pulled out the engine and repaired but after he fitted it back, my Power Steering is hard and i guess it's not working anymore. What could be the reason? What he might have done wrong or forgot to do? I am worried. These mechanics ruin cars instead of repairing

[pwuser157216306436]

I further noticed that the Carburetor has been replaced with Civic's Carb and also an after market fuel pump. Is it possible to use accord's OEM fuel pump with this carb?

[Xulfiqar]

Good luck finding the factory fuel pump for this car, its a very low pressure electric fuel pump (looks like a tiny sized efi fuel pump) and this car has a dead head fuel system (no return line from engine to tank, it only has a supply line)

I dont know how this afternarket pump is plumbed, did someone add an extra fuel return line?

The fuel pump relay is a bit unique too, it has a 1 second key on timer (this primes the fuel system like an EFI car anytime the key is spun to “on” and then the actual run on is latched with the rpm signal, as long as there is an rpm signal to it, the relay is latched and pump keeps running. (Like an efi car)

You can try to use a suzuki low pressure intank pump.

[pwuser157216306436]

Thanks @Xulfiqar bhai for such a detailed input. We lack such professional advise from so called mechanics these days.

Yes, whoever has replaced the carb has also added a return line to it. I don't know how but it's working somehow.

So technically, what I have inferred, I will need it's OEM fuel pump and also it's OEM carb to support it? As this Civic carb do have a return line and OEM fuel pump won't support it/need a return line?

Another question, will it be a wise decision to do so to revert it back, considering the abuse mechanics have already done? How easier it will be? Keeping in view the limited temperament and knowledge of mechanics these days. Sourcing parts is easier than making them do such job professionally.

Or

Just keep running this fragile setup until I can afford to swap it with F18B or other such EFI engine?

I wish we had passionate professionals here in Karachi

[Xulfiqar]

The return line has nothing to do with civic vs accord carb, the problem you will face is that the civic carburetor has narrow throats as compared to the accord one and because the main and power jets are not removable in thse you cannot change the fuelling

Now comes the big problem, this engine has more displacement and has a longer intake which means very strong suction at the carb, and because you have installed a narrow throat carburetor, the carb will literally dump fuel into the engine

Imagine like sucking a coca cola can with a thin 3mm juice straw compared to a regular 5mm one.

You will get a lot of drink on very little suction.

@Xulfiqar bhai 'Brake Lamp' indicator turns on when I drive. What could be the reason? Brake oil level is ok. Does it indicate anything serious or just an electrical malfunction?

[Xulfiqar]

The little wide thin indicator at the bottom of the pictogram of the open doors?

[pwuser157216306436]

Exactly! That wide one at the bottom of open door indicators
