The 205 engine has a lower compression ratio than the 185... |
...this is because the piston is different on the 205... |
...if you look closely the 185 piston is nearly flat on top... |
...and the top of the 205 piston is dished |

Note the cut out in the piston skirt for the oil squirter |

The pins partially removed |
There are several differences in the design of the piston |
Note the lack of oil hole on the 205 piston |
The ring grooves look to be in a very similar position |

Rather oddly there are 4 pieces of metal inside the 185 piston, each side of the pin??? |
