Marketing Manager - Bridge Classic Cars
Classic car technician Jonn has completed the PDI on our 1976 MG Midget. It is now ready to be delivered to its lucky new owner. Jonns notes about the work completed are:
Drain coolant header tank and replenish with new anti freeze.
Get car round into workshop and raise on ramp. Inspect underneath for signs of knocking on floor. Found exhaust been made and stting close to rear axle and floor. Drop exhaust and grind away section of rear floor to add clearance and remount higher in relation to where it was. Grease all points. Lower to floor and check carburettors. Remove suction Chambers and pistons and clean. Use vernier to set jet heights to approx 1.7mm. Reassemble but pistons sticking in Chambers. Found air filter gaskets protruding over carburettor edge not allowing Chambers to sit flush. Cut off excess gasket from both air filters and retry. Chambers sit flush and pistons return freely. Fit P clip to fuel pipe to secure to air filter bolt. Replace both ends of rubber fuel hose. Lower to floor. Torque all wheels. Take outside and run up to temp. Adjust mixture and carry out road test. Drives better but knock still present. Get back in and rase in air. Check gearbox mount as knock seems to come from this area. Fou d metal on gearbox mount hitting floor. Fit piece of rubber between mount and floor and take outside and retest. Ok now. Bond gear knob back onto stick. All ok.
