Hello,

This is a downloadable PDF sheet, relating to the carburettor shown in the title of this product page.

You will receive the link to download the PDF sheet, as soon as you have completed your order.

You will NOT receive anything through the post – THIS IS NOT A PHYSICAL PRODUCT.

You will need a printer, or a storage facility on your computer/mobile device/tablet, to view and store this PDF file.

We need your postal address during order checkout, because this process involves a financial transaction between you and classic carbs UK.

But we will not be posting any physical parts to you (unless you have included additional, physical parts in your order).

The diagram is mostly in English, but some variations might be in Italian or French.

The PDF will typically show you an exploded drawing of your carburettor, name of each individual part, part number of each individual part, and the original jetting and choke venturi calibration.

The download will be instantly available to you, and you can use it to help you rebuild, restore, repair and calibrate your weber carburettor(s).

This is NOT a generic ‘How to repair your weber’ manual, it is a specific spec-sheet diagram, showing you what you have and what parts it is made of.

This is Genuine WEBER factory publication, with Precise technical details, that can be very useful towards successfully bringing your weber carburettor back to life!

Add it to cart, proceed to checkout, add your contact details (incl. address), and select Paypal, debit or credit card, or bank transfer to pay for your order.

If you need any assistance, email us at [email protected]

Thanks,

Emmanuel
