If you google the carbs it will give you start up settings for the carbs,along the lines off screw this fully in then back off 3.5 turns,if you get my drift.
I have these fitted and they’re wonderful. Get the Dell tech book- excellent advice and set the butterflies with feeler gauges before fitting them. You’ll need to remove the engine to remove the old manifold etc but you’ll be able to fit the carbs to the engine before refitted it. You may have to remove the air filters depending on the design. You have to fit them ‘in situ’ in a beetle but a van has much more space and the carbs are diminutive For decent duel hose, a vac advance (with anti pulse) and fit your breather to one of the carbs and once they’re set up (a doddle) they are fit a forget.
Had these fitted but not tuned yet. Went out for a quick spin before MOT tomorrow and the motor seems to be have a bit more go- prob as the throttle opens fully rather than nearly fully open due to the Weber progressive awkward cable angles not working well. Nice little growl from the intake which must add 50hp on it's own. Flat martin opted to fit them without dropping the motor which he said was a bollok of a job but they're in. need to get them set up on a RR to get jets and chokes bang on. Do I risk running it to techenders before it's tuned?
Get yourself a wideband O2 sensor and weld it onto the exhaust. Far better than a rolling road and will give you months of tinkering and another gauge to worry about! I have the innovate one on eBay for £175. At least on a DRLA the jets are quick and easy to change. I am a big fan of the CSP bell crank linkage as I like the lightest gas pedal possible.
what have you done with your old air filter @Mattlad ? just wondering as i have a pancake type and would like to go back to stock (mine should have a paper element with the plastic box)
