Will these work well with my 1.7?
My FI was working when I bought and torn down my car (haven't registered and driven it since I bought it) but last week I took out the spark plugs and they were black as soot. (Fuel pump was hot wired to the coil too so it runs all the time)
Would it be worth $100 to buy this set-up to keep as a spare way up here in Northern Canada?

What a bullshit artist this seller is...it's people like this guy that don't do a single positive thing for our 914's.

Don't lie in order to sell an item, this carb setup does work, but it's a comprimise and should only be used as a last resort or out of total desperation.

The biggest problem with this setup is not the carb. itself, it's the piss-poor location. The runners are too long and not properly designed to be a "wet" intake setup. As the airfuel mixture goes down the tubes, the fuel will want to cling to the sides of the runners and will start to drip down the runners....liquid fuel does not burn as well as an atomized mixture.

Dual carbs are much, much better than the single carb since the airfuel mixture has more of a straight shot down to the intake valves.

As to CFM, a single carb of ~200cfm should be okay from the carb. calculators I've seen.
