Yes it has the wider piston rings, it couldn't have anything else as they had discontinued the narrow rings and this was the replacement given in the 1975 parts price list. David

A picture of the piston with rings part #400560 (picture saved from ePay many years ago), this was listed as the replacement when the narrow rings were discontinued. David

The narrow piston rings are A-33-13 (also used on early 13B engines), when these became obsolete they used replacement piston & ring set 400560. And the wider rings used on later 13B engines are 200862. David

Maybe post #9 here will help, I added a short guide to reassemble the 13B starter (note 20A engines are different, as they were made in both rotations). David

The type 133 is actually the engine for the military version of the Kenco pump, as seen here; I suspect the original engine was red, as the rest of the pump is. Also the standard muffler was not supplied with a type 133, due to the military using a different type (also shown in the above thread). Need to check the information for the other engine types used on these later Kenco pumps, earlier ones didn't have the engine directly bolted to the pump housing. David

Will PM you tonight, only have the diaphragm, cover gasket & plastic check valve (not usually required for later engines). No one seems to make the crank seals in the sizes O&R used (expect the front crank seal, which someone on here found a modern replacement for), we have to use O rings to replace them, no idea how long they would last, mine only get run for demonstration purposes, note they are very loud. David

If you meant the Creme Lure generator, the batteries will not start the engine, they were used to boost the ignition circuit only, probably not a good idea to add extra voltage to boost 50+ year old coils. As with anything using batteries you may find some old ones fitted, I did in mine, of course they had leaked & made a right mess of the battery terminals. Lastly the plastics used for the tank & frame do not age well. David

As it's the Perry branded version I guess you are in the UK, I still have a few reproduction carb diaphragms for these older type 13A engines. The owners manual can be found as a pdf, in section 4 of the manuals thread here; Note these engines aren't the most reliable things, even with a carb rebuild and avoid modern ethanol tainted fuel, as it does no good to vintage engines and the seals & fuel lines, etc.. David

If there is anything I can help identify, let me know the part number(s). David

If it has a type number stamped into the cylinder plate and/or the crankcase, then I could look it up in the list & see who it was rebranded for. David

Engine type 115 was used on the Kenco water pump according to the list I have, also seen one fitted to a Kenco pump in a thread on here, older Tiny Tiger Model 300 usually have engine Type 111. David

That is a Type 133 engine, they were supplied to the military as spares, for use on the military version of the Kenco pump; David

Part #21 on that diagram is a screw, this is used on earlier engines with a tapered output shaft, later engines use a D shaped shaft for the clutch assembly. David

They were actually made by the K & P Manufacturing Company, everything else is just a re-brand, aka badge-engineering. David

Apologies for not getting back to you, been knackered with the heat, work & change of medication recently. The con-rod bearing, are you talking about the lower one for the crank pin? and if you are, does it have a slot in the bottom on the con-rod? this determines which type of bearing should be used. I have collected bearing info from the parts diagrams I have (1961/62/64 & up), need to check if I have more 1963 info, as they changed the bearing types from Oct 1963 to using steel cages, instead of the nylon plastic ones.
