 |
|
I bought a 69 bug...before I started tearing it apart to replace a cracked head it idled but roughly...i thought that was due to the cracked head...i replaced both heads and when I went to start my bug it refused to idle, I checked for vacuum leaks, bad plug wires, and everything else
Like a dumb dumb I decided to check the carb last...this is what I found
Also I was wondering what goes in these holes and which hole do i use once I'm done cleaning the accelerator pump

Those holes allow you to adjust the accelerator pump for the right amount of squirt. Use a little washer and cotter pin.

Start with one, drive it. If it drives great, it is right. If it appears to bog down from too much gas, it is too tight. Vice versa. There are only a few holes. Start in the middle.
And read this... http://www.vw-resource.com/accelerator_pump.html

Another way to check the pump spray is on the bench with the bowl full of fuel. VW actually had a tiny adapter that went over the brass spray nozzle and you could measure the output. You can do it without by pulling it down and seeing how much fuel you're getting at each setting. When you pull the throttle, you should see an immediate full spray out of the nozzle.

Just an update
Still having issues. I rebuilt my carbreuator, but I'm having a hard time getting the accelerator pump to seal. When I open the throttle gas squirts out of the side of the accelerator pump at the diaphragm...i have rebuilt webers before so I am familiar with the process...i am thinking about using the old diaphragm. Has anyone else experienced this? |

I always flatten both surfaces at the diaphragm pump. The body and the cover. They will leak if you don't do that. There's also suppose to be a paper gasket between the cover and diaphragm as well.

The rebuild kit I ordered did not come with the gasket between the body and cover, and when I took the carb apart there wasn't one...do you know if they sell that gasket individually? |

I don't know if it's sold separately. I'd try flattening the sealing flanges on the pump/carb body and then it's cover. They are usually pretty warped. It may seal just fine with just the diaphragm if you flatten both sealing surfaces on a piece of glass (or something dead flat) w/220grit paper on it. The last carb I did was a German Solex 34-3. The accelerator pump flange sealing surfaces were REALLY warped. I laid a flat edge across both the body side and the cover. It was shocking.

I will check for warppage when I get home, bothbsealing surfaces looked pretty flat, but the eyeball isn't always trustworthy |

Think about making your own gasket from rubberized sheet gasket, available at auto parts store.
I drill any holes first before cutting.

Update...
I checked to see if the accelerator pump cover and body were warped. I sanded them flat and installed the new accelerator pump diaphragm....still leaking like crazy
I didn't have time to get gasket paper last night but I will attempt to purchase some today
I am trying not to let myself get too discouraged... I have a set of dual Kadrons and a Weber progressive sitting around...if I can't get my solex solex 30 pict 2 to work I might throw one of those on there. |

No need to get discouraged. A simple gasket should fix the problem.

Thank you for the positivity and support...I found this laying around the shop at work today, I think it will work to make a gasket out of

Update...
I GOT THE ACCELERATOR PUMP TO SEAL!!!!!!!!!!!!!!
Gasket paper and patience...now instead of only idling for 15 seconds it idles for about 30 seconds then shuts off...
Could it be that I have too much squirt from the accelerator pump? |
