Petter M 1.5

Hi Chaps,

I spent an interesting but not very fruitful morning trying to kick some life into my newly acquired 1.5 Hp Petter M:

Crank, crank - - - No Spark :(

Clean magneto points,

Crank, crank - - - No spark :(

Strip magneto - - - secondary open circuit :(

Swap magneto for known good item.

Spark! :)

Crank, crank - - - No Fuel :(

Strip mixer

Q. The books I have indicate that the bigger 'M''s have a cone type fuel collector, mine doesn't. Is this normal for the 1.5 HP? The atomiser on mine is just a block with a few holes in it.

Clean / rebuild mixer.

Crank, crank - - - Nothing :(

Crank, crank - - - Compression seems a bit feeble. :( :( :(

Whip head off.

Bore looks OK, not oversize, no wear ridge, not much piston movement. New Rings required?

Crank, crank - - - fuel getting in now :)

Reassemble.

Crank, crank - - - Nothing except a blister on thumb (the one that's kept out of the way when cranking - b*****ks) :(

Swift application of easy start - - - Nothing but smoke from exhaust :(

Check air valve clearances (desperation setting in) - - - OK but reset to

Crank, crank - - - b****r all!!!! :(

Chucked a couple of squirts of oil down the plughole to gain some compression (and some more easy-start).

Crank, crank - - - more smoke from exhaust, otherwise b****r all :(

Fed up - - - Get coffee and go and do something else! :)

So .................

Is there something missing from my atomiser assembly?

and

To ask the question for the thousandth time, who is the best bet to supply piston rings?

and

Any other ideas?

Best regards but a slightly dejected,

Mark
