Iam guessing that its a down draft weber I have done those on vw's but always had to change emulsion tubes or jets and they are expensive, if its for a 2000cc its going to need some work to get to work right on a 2300cc engine, what dont you like about the stock carb? just curious, no performace, bad milage, dont know what you have for junk yards up there but you never know what you can find, plus there just a fun place to be
The stock carb is a pita...if it works, it's fine for basic use...but once you start having issues they are not worth the effort and they are not exactly the best for performance.
There are a few dozen (it seems) vacuum lines going here and there and back again that can cause problems and finding the line that is causing the problem is not a pleasant task...not to mention if the previous owner happens to have tried to modify it or was trying to troubleshoot and took some lines off...or they fell off...
When I bought my 88 with the 2.0 the PO had done some work on it...he said his FIL was a mechanic, but I guess he was not familiar with these carbs because he had pulled a bunch of the vac lines off and plugged them up...it would not run right initially but I finally got it running...and then the float managed to raise up and it kept flooding...lost more gas on the highway than I actually burned until I figured that one out...
I saw one for sale in Ontario a few weeks ago and was tempted to contact the owner because it listed very low mileage...I could have just removed the carb and plunked mine on there and had a pretty decent truck...but it was gone before I could respond.
Anyway, once I swapped the carb and intake I had about two years of pretty much trouble free driving with it...until I overheated it...then the fight started...
EDIT: Oh, and there are still restrictions on removing things like the EGR and air pump...if the MOT or MOE finds you have removed anything it is a fine ranging from $400 to $5,000...and they can impound the vehicle on the spot if they choose to make your life interesting...so to the OP...keep that in mind when you modify anything...leave the pump and EGR in place...
