Tomorrow I would try to assemble the caliper pistons.

But, I did only 1 caliper and 3 more were still remained …

Tip to repair rubber parts

I disassembled the rear axle before. There had been no progress on it because I started the repair of the fuel tank during my summer holiday.

( These bolts were also fixing the clutch master cylinder penetrating the frame. ) ( 3 ) & ( 4 ) Separate the linkage rod from the brake pedal , and remove the brake master cylinder together with the linkage rod. ( The linkage rod and the pedal were fixed by a split pin. ) ...

One week passed and a long-awaited weekend came. I changed the engine oil , Put the oil from the sparkplug holes and rotate the crank by hand , Tighten the idle adjust screws to the end and return 1 turn , At last I turned on the ignition praying the moment of the engine starting. After hearing the sound that the electric fuel pump sending the fuel , I pushed the gas pedal a few times then turned on the key … VROOOOOOOOM!!!!! The engine started with the first ignition!!!!! ☺︎☺︎☺︎ The engine revived for the first time in 10 years! YES!! I did it!!! I haven ’ t done the accurate adjustment , but the idling was stable and it seemed good. Tomorrow I would do the adjustment for the idling and throttle synchronization ♪

The day my "onboro ALFA" would revive
