Thanks datsa73, pictures would be appreciated. I might look at a battery place, I know where there is an Interstate Battery store nearby. If you could post pictures of your installation that would be appreciated. I am not good with electricals.

The diagrams that are making me lose my mind looked exactly like this:

I have a feeling this is the book that I lost.

Okay not a worry, I found it. And it does have very detailed 3d wiring diagrams that I would recommend everyone to use. I can possibly scan this one in for everyone to use when I get a chance.

Now that my panic attack is over, I also took off the stock carburetor today to prepare for the Weber 32/36. I found this weird gasket with a sleeve on it. Do I need to reuse this for the installation? If so, what hole does the sleeve go into?

How do you guys recommend sealing the carb adapter. I was thinking of not using any gasket to the manifold, just sealing it with a rubber compound/wet gasket and using a paper gasket between the adaptor and the carburetor base.

I also plan on removing the stock carburetor linkage to modify the Weber. Going to work on this tomorrow.

The insulator with tube goes on the manifold.

Use a stock gasket both sides of insulator. Usually you can reuse the stock gaskets unless they are torn.

Use a standard Weber positive-compression gasket on the adapter.

16174-H3900 INSULATOR-CARBURETOR



The primary purpose of this plastic spacer is heat isolation. It keeps the carb from overheating.

The plastic spacer is designed to extend the carb bores, so don't cut the center out of it. Newer ones use an extender on the primary (a metal tube goes in the plastic spacer). This extends the bore down close to the floor of the manifold. It makes a huge difference in driveability--for the better.

With a Weber you don't need this
* the tube wont extend the larger Weber bore
* Weber gasket is insulating type 5mm thick

The gasket for top of manifold is included with a carb kit
Or just re-use a good old one, if you can peel it off the insulator in one piece.

no sealer is needed. Just get the gasket surfaces scraped perfectly clean.

So the carburetor kit I bought second hand did not come with throttle linkage. Well it did come with this U-shaped bracket that doesn't look to "crash-hot". So instead I decided to disassemble the throttle linkage on stock Hitachi carburetor. The throttle lever bolts straight onto the Weber !! Pretty easy modification. Tested the linkage and both butterflies open full 90 degrees. Pretty happy with this, I can't wait to get the engine started.

Is there anyway to test run my engine safely without a driveshaft? Or is that a no-no?

Sure you can run the engine w/o driveshaft. Put it in neutral so it doesn't sling gear oil out.


Redline sells the cable bracket.

Thanks DD I will look into the cable bracket. If you scroll a few pages back it looks like my new chrome rocker cover has a custom bracket welded on.

There is alot of chatter on Facebook about Weber "genuine" carbs. Mine is not stamped anywhere with the Weber logo, it only has a round plastic sticker near the fuel inlet with "Weber North America - void if removed"

Does this mean my carburetor is not "genuine" and if so does it really matter?

In the long run I plan on installing sidedrafts anyways when I can afford them,
