As you may know, I bought a 914 last week, and it came with barely functioning Weber IDF 40s.
Well I got the first one apart, and here is what I found: Main jets: 115 Air corrector jets: 200 Idle jets: one 45 and one 50 Float valve: 175 Main venturi (choke tube): 28 Aux venturi: 4,5 Emulsion tubes: F11 Accel pump jets: 50 FW Accel pump bleed back: 55 There was enough crud and rust that I have opted to go for the full rebuild. The float valve had visible wear, and the accel pump diaphragm looked kinda wrinkly and messed up. One of the idle jets was missing its o-ring, and one accel pump jet had 1 extra washer. Obviously one of the idle jets is wrong, does the rest of this sound ok for an engine that is probably a 1.7 or 1.8? The PO said it ran good and got good gas mileage before it got all clogged up. One air bypass screw was about 1/2 turn out, the other was completely closed (and rusty)... perhaps because of the mismatched idle jets? |
