Upgrade your aircooled engine with this twin Weber 34 ICT carburettor kit, now supplied with a premium CSP bellcrank linkage system for superior throttle control and reliability. Designed for 1300cc–1600cc twin port Type 1 engines, this kit delivers improved performance, smoother running and excellent fuel efficiency—ideal for both daily drivers and mild performance builds.
Twin carburettors allow each cylinder bank to receive a more direct and balanced air/fuel mixture compared to a single carb setup. This results in improved throttle response, increased power and more efficient combustion across the rev range. The Weber 34 ICT is renowned for its simplicity, reliability and drivability, making it one of the best all-round upgrades for aircooled VW engines.
The inclusion of the CSP bellcrank linkage is a major upgrade over traditional linkage systems. Mounted centrally, it provides smoother operation, improved synchronisation and more consistent throttle response. The original EMPI linkage is also included in the kit but is not required for installation.
Kit Features:
• Twin Weber 34 ICT Carburettors
• CSP Bellcrank Linkage System (upgrade)
• Aluminium Alloy Hex Bar with Steel Ball Ends
• Sealed Aircraft Heim Rod Ends
• High Flow Aluminium Intake Manifolds
• Heavy Duty Steel Linkage Mounts
• Gauze High Flow Air Cleaner Assemblies
• Coil Relocation Bracket
• Brass Fuel Tee & Fuel Lines
Factory Jetting (Pre-Installed):
• 1.75 Needle and Seat
• 130 Main Jet
• 52 Idle Jet
• F7 Emulsion Tubes
Supplied ready to run for standard 1300cc–1600cc engines. Engines above 1641cc will require re-jetting, particularly the main jets, to achieve correct fueling.
For best performance, twin carb systems should be properly balanced and ideally tuned on a rolling road to ensure smooth running, correct air/fuel ratios and long engine life.
Important Notes:
• Will NOT fit 1200cc engines
• Heat riser ports must be blanked off when removing the original manifold
• Fuel pressure regulation may be required depending on setup
