The 1973 Mercedes 250 has been in the Bridge Classic Cars mechanical workshop after our paint and body had finished with their jobs in this classic German saloon car. Our technician Jon has been working his way through the mechnical work the car needs.
”Clean block and manifold. Clean all exhaust flanges. Fit new gasket, refit manifold and secure. Refit all pipes and hoses. Resecure throttle to block and reconnect to carbs. Refit exhaust downpipes and front pipe and secure. Reconnect battery and turn over. Battery low, put on charge. Build new front bumper. Secure chrome’s to crash bar and mount to car.”
”Continue with rear bumper. Disassemble old rear bumper and remove crash bar. Clean and paint bar black. Build chrome’s. Tap out threaded holes. Mount chromes to crash bar and mount to car and secure. Attempt to start again but battery still low after been on charge for hours.”
”Get off ramp and tidy area. Remove battery for replacement and found battery tray corroded and holed.”
After Jon had discovered the rust on the wing and the battery tray, the project was briefly turned over to our fabricator and technician Greg to remedy and get the areas repaired.
With the repairs finished, the car could be moved back into the main mechanical workshop for our technician Jon to carry on with his recommissioning of the car.
”Refit battery hold down brackets. Fit new battery and secure. Refit coil and ballast resistor. Crank over and check for fuel at arbs. Starts, runs and idles now but has an air leak on front carb. Also needs timing up correctly and testing. Fit rubber over rider trim to front and rear bumpers and trim to length. Start stripping front carb.”
‘Attend ”to air leak on front carb. Remove carb from manifold. Tighten base plate screws and e3fit. Make all connections and test. Run up outside. Fuel leak from return valve. Remove valve and strip. Diaphragm gone hard but clean out, rebuild and refit. Still weeps under acceleration. Pla e rag around it while I set ignition timing. Run up, seems OK except for under heavy acceleration. Disconnect link rod. Rear carb seems to stumble when revved. Front carb seems OK set idle vacuum control rod. Leave other settings until fuel leak cured.”
