Hi All
I've been told about a conversion where you fit a single, twin choke weber carb on a T25 air cool. I can't seem to find out anything about this using Google, so presume its not that common a conversion? Does anyone know anything about this conversion? Is it better than the standard twin solex set up? Or is it uncommon because its not very good? Any info gratefully recieved.

JK do a single webber kit,
I bought mine from Street Style and Power, found it worked straight out of the box, depending on what size boots you wear you can get 25-28 gal from it, but you loose acceleration in first an second gear,s it works but not a rocket ship, originally fitted to the latter engines in Bays so I was told by Simon (toomanytoys) bigest headache when setting up is Type 4 engine fitted with twin vacum on dizzzy Webber carb has only 1 advance only so you have to find the sweet optimum blank the retard off or leave open.
Dont run a Type 4 now I converted my Air-cold to water and put in a smoker, aqs my sig indicates.

these single carb kits do really strangle the performance of the engine.
weber ict s are no better really.
the best kit (which also gives most mpg and power) is a pair of delorto drla or weber idf / ida, 36mm to 40mm chokes work best.
speak to
www.raceshack.co.uk for more info
or jim at stateside tuning.
dont waste your cash on anything less.

Mine really increased performance but was fitted with a sports exhaust and crossdrilled airbox. T'was a bugger to set up and mpg went thru the floor! Sold it on ebay blooming thing...

It was a wsser boxer but still had the same hassles! Some people have luck with them and some don't and thats on lots of engines not jus Vw's even escort owners I knew have had probs with them! The twin Dells are a much more refined choice in my opinion I was tempted to try that but got a new van..
