Re: Weber carb

You might have to modify the Manifold where it connects to the engine, I have a spare 1.6DGT Manual Choke Carb for sale if you want it.

Re: Weber carb

Anything is possible if you have the tools or the money. I'm not saying it will make a difference or that it is practical but I have been told you can fit different Carbs with modifications.

Re: Weber carb

Not always. The stock cam is very weak too.

You could fit Twin weber DCNF 36's or 40's They would go well.

Re: Weber carb

The 'hot' camshaft will make better use of improved carburettors. Doing one without the other is often a waste of time/money, if only because you have to re-tune if you later change the setup (see below).

There are companies that can regrind your camshaft (the cheapest option).

Incidentally I don't know of any bigger carbs that fit the weird Tipo manifold, I suspect you would be better to use an aftermarket FIAT 128 manifold for twin carbs (Bayless in the USA, etc.)

Choosing jet sizes for the carbs needs to be done by someone having a selection of sizes and a fuel/air mixture meter (ideally a rolling-road as well). This gives better economy and the engine will live longer if not too lean (melted pistons etc.) or too rich (oil diluted with fuel).

I wonder if your petrol is as expensive as ours?

-Alex
