Once again thanks lads, all good info, I'll check out the circlip at the weekend. Re the stator, lets see what's in there, I do have an old Indian Lambretta points stator and I think there is some similarity with the coils/core so with some luck some bodgery could ensue lol

with the indian 1 you'll prob find the coils are same but diameter of base plate is different ,so when coils are bolted on there either to round for the flywheel or too small a diameter . i know thats the case with electronic staters ,same coils n pick ups but diff spacing , reckon it might be bodgeable but loads of work , H

The replacement engine that I bought is actually an LML reed valve electric start jobbie in bits having been stripped to find a miss-diagnosed fault. I've had to get it delivered to a scooter mechanic friend to sort out due to the scooter work embargo.

from what ive heard there generally good lumps ,an some tuners prefer em as theve got good potential to play with. H

That's good to know H, I reckon he'll be wanting it to go faster when he passes his test and fettling the LML will probably be cheaper than sourcing a 200 engine?

Right, my money is still on this being a Douglas 152L2 125cc 3 speed engine, '59 - '61. That 503 Amal carb was used on them, not aware of any other model which also used. Ive seen Douglas motors stamped with both Piaggio and Douglas, back of the clutch cover may also be stamped.
Its not really an engine you'd want in a PX, i'm curios about the back wheel though, the motor would have been on 8" wheels with a very small brake hub, not compatible with a PX 10' hub without some serious modification, and does it have 4 gears? may be a bit of a hybrid if it does..
Yes the fly nut is standard thread.

yep ,totally agree with bryno , douglas used piaggio cases first ,only swapping to there own 1's marked douglas about 60-61 with the vbb1t /sportiques from what ive seen ,an that its a amal carb helps to confirm altho carbs can be swapped , have checked my douglas cases an there a 1 number 2 letter prefix (5EC) so def different to piaggio an moto-vespa stamps, . i'm trying to remember my amal carb codes ,are you sure its a I an not a 1 , as there usually 2 numbers ,1 being the choke size in inches an the 503 the style/type of body casting . thats what i can remember from later monoblock/concentric amals. an i bet the rear is still a 8" wheel ,with a single brake shoe pivot , i dont think they can be changed to 10" without heavy engineering , H

was waisting time sticking "vespa " into flea bay as sumtimes bad listed stuff comes up cheap, like a crank for 3 quid 5 miles from home ,result . anyway if ya type in "vespa MOTO spanish engine believed 150s" ,a spanish piston ported lump like this comes up ,an it shows the engine number an pre-fix which is def not like yours so the case for douglas is stronger. also has some other info ya might find interesting ,its at 125quid 4 days to end an no bids ,worth keeping a eye on as bryno reckoned they werent worth much but your douglas was ,give ya a idea what to ask for ,maybe get enuff for a px125 lump, or if sticking in vespa in first 200 results theres a dismantled lml reed valve lump with crackered crank , for about 4 quid but to far away from me to get it ,cranks about £100 an other stuff to build it would stand ya well under 200 bar ,just a thought ,idle 1 anyway, Henri

Bryno and Henri, many thanks for taking time to research my engine. The Douglas case is staking up but I can assure you that the rear wheel fitted is definitely a 10", the scoot has Shwalbe Racemans fitted front and rear. I daresay the hub isn't on properly, I will investigate when I get a chance. I did look at the gear quadrant as advised and confirm that it has 3 notches. Also tried unsuccessfully to see if I could get a spark out of it but I'm not sure I was connecting the correct stator wire to the coil. Also, how do you set the points with no window in the flywheel
Rest assured this engine will NOT be staying in the PX, I have already bought an LML125 reed valve electric start engine in bits. I got the seller to ship it directly to a scooter mechanic (good mate). Going off thread but the barrel is damaged and needs replacing and I have seen various adds on fleebay for 5port LML 150cc barrels and piston kits, are these any good and what sort of performance increase should I expect?
Thanks
Guys
Colin

the flywheel must be a later electronic 1 ,from a smallframe pk to fit on the smaller/earlier taper , its def a "bitsa" that engine . it could that the 10" rear wheel/hub is original as some older models did have 10" instead of 8" , gs models for instance , makes the lump more valuable to some if its right ,the difference is in the rim not the hubs ,an no need to thank me for time spent, i learnt along the way so i'm happy , i like to get the "ya learn sumting new everday " moment over early , then i can get back to my village idiot persona/career happy. the difference between 3 an 5 port barrel kits isnt massive when used on 3 port cases ,on a lml reed valve it should already be a 5 port barrel , so as there pretty similar in price i'd def stick with a 5 port . an so long as ya buy genuine lml from the longer established indian firms , enfield county is 1 ive used for years ,an mickey spares ,you wont go wrong ,ive had barrels n pistons off em an theve been fine,no probs .

Very valuable advice re Enfield County and Mickey Spares, their prices are a LOT lower than UK dealers sell them for. I have heard scare stories of pistons disintegrating whilst on tickover within 10 minutes of being put together but there are hundreds of backstreet outfits in India and it's good to get 1st hand recommendations
