Series 70 MKI 160cc with a G3 carby.

No decompression valve, and yep, it should have a trigger type (Sure Start) wind-up (Impulse) starter, with the chrome surround.

This is the 1971-1972 model I beleive, Although it could be 1970, can you post the serial number stamped on the engine? The serial should be here:

The only things that seem out of place to me are:
-The starter
-The red boot on the spark plusg (should be THIS)
-The Fuel tap (I beleive this mower had the whote plastic tap with red lever, not the black one)

Cheers
Ty
