Re: Single Venturi auto carb leaking (+startup issues)

I think i fixed it! Old valve seat, new brass tip valve, float was ok with no leaks but the height adjustment wasn't. Even though i had previously gone with the 28-35mm float height adjustment from the workshop manual, i had all these problems. So, at first i tried the 35-50mm (gt or 2.0 spec) which...

Re: Single Venturi auto carb leaking (+startup issues)

I will open it one last time today and check and readjust the float height. I'm also gonna dunk the float into a glass of water to be sure this time. If it's faulty i will try a new one. If nothing happens, i'm done. Not touching this carb ever again. I will go in the Weber route as soon as i can.

Re: Single Venturi auto carb leaking (+startup issues)

There was a washer (i forgot that i put one in) but the valve housing was really loose. I put the old one in with the old valve and voilà! It returned back to the exact! old problems and behaviour... Hot restarts are almost impossible once again, the bogging down is less than before and of course it...

Re: Single Venturi auto carb leaking (+startup issues)

I will reinstall the old valve and needle and see. I am just now finding that my kit had a little red gasket inside that fits the valve's thread... I believe it is meant to go there but the old one didn't have no gasket either and i didn't put it in... ( edit: the workshop manual shows no washer on ...

Re: Single Venturi auto carb leaking (+startup issues)

The brass float looked fine, do you suggest checking it again and replacing it? Is it worth it at this point? It had not visible cracks, holes or wear. The only other thing that comes in mind was that the needle i replaced was from an autolite kit and it had a pointy brass tip, but the one i took ou...

Re: Single Venturi auto carb leaking (+startup issues)

One year later. Literally. TLDR post incoming. After doing nothing for a year while still using the car as a daily driver, the startups became more frustrating and i decided to take the carb apart myself. Besides starting poorly, the other main problem is that when the car is hot, if i stop (in gear...

Re: Single Venturi auto carb leaking (+startup issues)

https://i.imgur.com/MLQPQD2.jpg Yeah, looking at this, my control link that moves the spring and the acc. pump is definitely broken... Some epoxy adhesive needed to make that into a hole again. I couldn't have been that stupid... How the hell was it hanging at the edge for so long and still working...

Re: Single Venturi auto carb leaking (+startup issues)

Update: Took the carb out myself and replaced only the diaphragm and the manifold gasket. I didn't have the time or experience to overhaul it properly but after that and a good clean to the connecting rod that goes from the linkage to accelerator pump, the car starts up very nicely with one pump and...

Re: Single Venturi auto carb leaking (+startup issues)

I have bought a service kit for the carb but didn't have the chance to fit it. I took the pump accelerator apart this afternoon to take a look at the old diaphragm, which is totally fine... but found out that there wasn't any sealing washer between the pump diaphragm and the spring! Is this normal? ...

Re: Single Venturi auto carb leaking (+startup issues)

If you want to stay with the single venturi carb and not change the manifold etc then this will be the one http://www.webcon.co.uk/shopexd.asp?id=697. You will have to fit a choke cable with this. I agree with 340 that the twin choke DGAV is a much better carb and will give you much more performanc...

Re: Single Venturi auto carb leaking (+startup issues)

Ok. Pumping the accelerator 4 times before starting will over richen the mixture because the accelerator pump squirts fuel directly into the carb ventury when it's not sucking in any air so it sits in the bottom of the manifold until it mixes with the already rich cold start mixture when the engine...

Re: Single Venturi auto carb leaking (+startup issues)

So, let's turn this thread into a carb/startup troubleshooting session. Current state of my daily driver mk3 ohc 1.6 auto: New ap6fs plugs, gapped by hand to spec (but old ignition leads...) Coil ohms at 1.3, no ballast resistor, 12v system. Valve clearances done to spec. They were half closed. Neve...

Single Venturi auto carb leaking (+startup issues)

Hello everyone, my ford iv 77hfkba carb is leaking as you can see. It does it after i stop the engine at the screw next to the pump accelerator. https://i.imgur.com/7jzwMww.jpg https://i.imgur.com/xFutP4Y.jpg Is it the pump diaphragm? That screw with the drop of fuel is tight. I don't think it's ove...

Re: Brake problems not going away

The adjuster ratchet itself is probably worn out and not holding the adjustment. The mig weld on it is an old trade trick whereby the shoes are clicked out until they are lightly rubbing on the inside of the drum then the adjuster is welded in position to stop it slipping and releasing the shoes ou...

Re: Brake problems not going away

So, i changed the shoes with one another so that the part with the less surface on the top points to the front of the car. The other side was already ok, it didn't need any action. I did it myself in the end so i could take a look at the other drum as well. I pulled the handbrake 3-4 times and tried...

Re: Brake problems not going away

[ Are the shoes 100% fitted wrong Yes! They need to stay the same way up but swap one side with the other. Maybe not go back to that garage though :o Yeah, i am looking at the haynes' manual drum photo and it really looks not the right way... I can do it myself, but i have to also change a rack gai...

Re: Brake problems not going away

Your brake shoes are the wrong way round i had that suspision when they changed them in front of me in the garage i go to, but i remember them trying the other way and they wouldn't fit. Are the shoes 100% fitted wrong? It's the 8" drum system on a MK3. Also, sometimes when i go in reverse, th...

Re: Automatic Capri slipping out of gear??

Are you sure it wasn't in gear while still revving up? Are we talking half a second delay or a couple of seconds? It was trying to upshift, right? If it was low ATF in the transmission you would feel some lag while it's trying to get to the next gear but it's delaying. It's maybe this but i wouldn't...
