I have a 1600TP with the standard solex carby (34pct I think?). Have a bit of a flat spot (so whats new).

My question - I have a chance to buy a 40mm DCN Webber and fit it on - Good idea?. How much better will it be? I assume I amy need to rejet for the 1600, are they readily avaialable.

personally i think that 40mm is too big for a 1600tp but ive never run one. i prefer the 32/36 twin barrel progressive webber as pictured here

it runs good goes like a cut cat

Depends on how cheap.

Are you running a 009??

A NEW 34 pict and a SVDA dizzy will set you back near on $500

Personally i agree with Barls, and like the Prog. Easier to jet and more available. Just need small hands to tune the f@cker!

If you can pick it up for under a $100 - why not.

Otherwise get a 30 pict and a conversion plate

you dont need small hands if you get the one of a lada niva as the adjustment is at the front or a new one but thats about $600 new

Have a look on ebay. There're a few well priced single carb kits on there at the moment

for starters just run a kit thru the carby, cheapest option . As it could just be the pump jet diaphram thats stuffed . Unless the motors modified its easier to stick with the stock carb.
Ohh check for vacumm leaks.
