Help! Weber 32/36 Install Issue/Engine Knocking

[Cole Deleon]

My brother and I woke up this morning with some completely undeserved self confidence that we chose to apply to attempting to swap out my old Weber 32/36 for a shiny new-ish (DGAV-33B1) replacement on my 75 2002. We worked through the checklist, the swap seemed fairly straight forward, we then started her up and drove victoriously through the neighborhood on a sunny day here in the Pacific NorthWest. Started up smooth, the illusive idle/stalling issue I have been chasing seemed to be fixed, time for more celebrating/debating next project ideas. After an hour or so, I went to start the car and head home and after a couple cranks I heard a rather terrifying knocking/clanking under the hood. I will do my share of googling and searching but wanted to kick off this thread as my brother's wife isn't loving the new orange immoble decoration in the garage of the house they moved into....36 hours ago. Will likely wear out my welcome in the first week if I can't figure it out or get it towed in the next few days. 

 

Any thoughts are greatly appreciated.

Did the car start, or did the clanking happen when you were cranking?

I would check to make sure all the Weber parts are accounted for (throttle plates, screws, aux. venturis , etc.).

Hope all  your tools are accounted for as well!

 

Or...could be your brother is having some fun...

I've seen that clip that guy is mean, but it's hilarious.

[Cole Deleon]

haha a joke that runs about 8 hours too long sounds about right for him.

 

Clanking did happen while cranking and sounded like something I shouldn't try and push through. Headed back out there tomorrow and will take stock of all parts/tools. Kinda hope that's what it is but also kinda hoping it's something a bit less obvious than leaving a wrench in there ha. Just for the sake of my own ego that's already pretty damaged after the days work. 

 

Thanks John!

This probably has nothing to do with your carb. Time to do some basic troubleshooting: compression and leak down test, 

[Son of Marty]

I'm with John the carb it's self would not cause this if I understand your description. I would pull the valve cover just to make sure all is in order there but it is possible a carb part or something went down the intake.

I vote for dropped wrench in the valley somewhere, or hung up on the exhaust downpipe.

 

I have a yellow PicQuik screwdriver that did 3 seasons in the wedge beside the pedal box...

Thanks all! Sounds like I will spend tomorrow looking for a wrench, a loose screw, a screw driver, or maybe even a Junior Mint...

 

Will report back.

Post a sound clip.  There are guys on hear who can tell you the missing wrench size from the sound or how many stimulus checks it will take to fix.

Does the clank have rhythm while cranking, like does it make you want to dance to it, or is it random like Bohemian Rhapsody?

Air filter hitting the hood?

[John76]

Is your battery secure?  Don't see a tie-down strap....could have shifted and knocking on something.

I'm just here for the dog pic.

@dangWas a little too terrified by the sound to boogie to it but the clank did seem to have a bit of an even cadence to it. 

@tmeClosest guess to the amount of stimi checks it takes to fix can have the roughly $12.32 that will be left in my bank account. 

 

Headed back out to my brothers this evening to begin the search. Is this a decent order of oporations? 

 

- Search high low & down in the valley for anything that shouldn't be there 

- Check Air Filter Position

- Check battery is secure 

- Take inventory on carb components 

- Pull valve cover 

- Pull carb & intake?

- Compression & leak down test 

 

Any other recommendations on good hiding places? 

 

Thanks,

It's something simple.
