    Hi, I recently bought a 3 HP tank cooled M that has a starting collar fitted to both ends of the crank. Obviously, there is no pulley fitted. The engine is totally unmolested and had sat untouched for over 40 years so is completely original.

    The collars each have a direction arrow that when fitted both point forwards so they look like original fitments, that said, the arrows are of different styles.

    Any advice on this will be most appreciated.

    Roland is bound to have an answer, but suspect it might originally have been a Petter Light engine generating off the flywheel rim with just that option to start either side. What is the engine number? as chances are the original spec sheet can be found on Paul's records here.

    Thanks, that certainly makes sense. The engine number is 58625.

    Will sort next week when home. One may have a grooved rim?
    Cheers

    A VA sent to Baker Perkins (Engineers) of Peterborough on 11/06/1927. Built as a std totation engine and the record is noted "extra LH collar fitted to other side" and an anti-clockwise starting handle supplied. It was built to P(lant) build spec. but no note of what it was intended to drive. Probably a dynamo or pump whose rotation direction demanded the engine be fitted with its normal starting side obstructed. So it would appear its always been like that. I'll index in the archive when it becomes available.

    Thanks again Roland that is very interesting.i will be refitting the collar and not a pulley. It looks like one side was more exposed than the other as one flywheel has more corrosion.......the rusty one has the extra collar fitted so.
