It was me being stupid the engine runs in reverse to what I thought, "stupid boy"

Hi, I thought I would fire up my Wheel Horse Raider 12 for the 1st time in about 18 months but I have a problem, the starter is turning backwards, it was alright when parked it up and I haven't touched any of the wiring, also the battery hasn't reversed polarity, how can this happen, as far as I remember it is negative earth isn't it ? Any ideas please, or have I done something stupid

Hi Colian, did Wristpin sort you out ?

Thanks dcp, what make is yours?

I found this photo courtesy of pmackellow of one of his Multigardeners and even though nothing in common about the deck the height adjuster is the same.

The German translation is "Before shifting come to a halt"

Thanks dcp, yes the Multigardener does have similar lines but I cant find anything on the net with any sort of height adjuster, even the colour is similar

Nice collection, shows how small those Mustangs really are.

Yes they are identical and swapped, the engine is basically 2 singles with a shared crankcase and crank. No I didn't check piston height or swap the rods so it is something else to look at.

Hi, I have swapped injectors and cylinder heads over.

Yes will probably be something simple just hard to find. I think the fuel pressure is ok, there is plenty of fuel returning back to the tank from the ( not sure what there called ) overspill hoses, I don't think it can be less delivery on the 2nd cylinder as swapping the feed from going to the 1st pump to going to the 2nd pump 1st and also swapping the pumps over would have swapped the problem to the 1st cylinder ( not very well explained I know ) I am going to try and make a new injector pipe so I can feed no2 cylinder from no1 pump just to see if I can make the smoke stop on no2.

Yes already tried that, it was quite easy but still the same

Valve timing was right, the " book " does refer to Bosch and traditional pumps so whether the traditional doesn't have spacers I'm not sure, the book is good in places but a bit vague in others, mine aren't Bosch they are Standyne. I may try a thin washer between the pump and tappet to see if it improves things, but I will turn it over by hand 1st to make sure the extra lift isn't to much lift.

I thought you had it for a bit Doug, took the bad side pump off and no spacer "page 36,drawing 80, item C" so took the good side pump off and also no spacer, the lobes on the cam shaft are good and lifting the pump tappets the same amount. I cant see any possible way now why its smoking, its just lucky that as its a twin with the same components for each so I could swap them about or I could have bought things I didn't need but its still not fixed Thanks for your help and Its back to the shed for this one for a bit, given up with it.

Good thinking Doug, thanks, I will see if I can do that,

Thank you Koen, had already seen it, not much help for stripping down but plenty of info on tolerances and assembly.

Another problem now, to get the camshaft out you have to take the oil pump off the far end and to take the oil pump cover off the generator has to be split from the engine, I presume it will be a taper fit but I cant see any way of getting a puller on, has anyone any idea how they can be split?

No air, no blocked breather, nothing internal as I have swapped over the pistons, cylinders and heads but everything looked ok anyway, I swapped over the fuel feed today so the smoky cylinder side gets the fuel 1st but still the same, only thing I can think of next is the lobes on the cam for the injector, cant see it being that but what else to check.

The fuel supply comes from the other injector pump, ie it is teed off, I did think whether the lift pump was supplying enough pressure but if I slacken the injector pipe off on the 1st cylinder the engine still runs on the white smoke cylinder, still making loads of smoke

That's a lot of rain, could you set up a water pump, if you have anywhere to pump it hat is.

The engine is air cooled, there is no water in the diesel or in the sump, and swapping over all the parts should alleviate the compression and injector, injector pump causes, I am not an expert but I think I have covered all the possible problems. There are 2 separate cylinders or barrels which are identical.

It is air cooled so I suppose the cylinder nearest the fan gets more cooling but it smokes when cold and hot, under load and at tick over.

Not really an old machine, from the 90's I think, but still perhaps of interest on here. I have a Ruggerini M150 twin cylinder diesel genset/welder with a problem, it white smokes very badly on one cylinder, I have swapped over injectors, pumps, cylinder heads, cylinders and pistons and it still smokes on the same cylinder each time, if I slacken each injector pipe off, the revs drop a bit, the same on each cylinder and still it smokes on the same cylinder, any ideas anyone please?

A couple if pictures of my Hayter Harrier, bought it last year off a guy who bought it new in 78, only needed a new carb diaphragm to get it running again, sadly it has to go, it is a very good mower but I just don't have the room for everything I've got.
