Interesting. Have you got a blow on the exhaust manifold where it meets the head? Richard

How did you get on? I'm just about to launch into solving a multitude of water leaks on an HW3 Richard

There is a door on each barrel giving access to the water space. Fitting the hoses is a pain, the longer on squashes and goes on. The shorter ones on the tee piece require careful juggling. You can't assemble them to the doors, then fit the assembly as there is a nut and stud behind the pipe (!!!). Before you ask, the 'S' shaped hose on the flywheel end is obsolete and unobtainable Don't bother trying to unscrew the 'filter', it will be very firmly stuck. It is easier to take the inlet manifold off. It isn't a filter, it's a noise suppressor - actually it' a pepperpot exhaust serving as an air intake Richard

Don't be surprised if the metal stubs on the doors have corroded through. I have replaced several Can't say I get a lot of trouble with Jubilee clips, apart from this horrible ones where the 'thread' on the band is pierced through Richard

All correct for a fixed speed engine Richard

I'm seeing industrial JP's that have now worn through the chrome in the liners. Leads to lots of oil coming out of the exhaust Richard

Don't bank on it! We have always changed the points per section a bit to encourage some parts rather than others. Bigger changes come from bonus points for starting points. Probably the most significant changes are which bits can be score in both directions - and they do get changed We are about to initiate Jon into this secret process as handed down for centuries, hopefully he will bring his own hedgehogs Richard

The organiser knows how many points per section, because they have set them. They know where the 'quiz' questions are because they have decided them. We haven't known the answers because Andy Tidy kindly set them for us - which automatically disqualifies him, we still decide it was unfair to compete It could be possible to both organise and compete, it would need some careful planning to be both fair and seen to be so. Richard

Just to say how delighted we are to be handing the organisation of the BCN Challenge to Jon. Well, he did win it - perhaps we could use that as a precedent. That would shake things up a bit! Richard

Good question. Probably! Richard

Oh, probably. That end can be a mystery because it often has non-standard pulleys fitted. As yours has The little one looks like it is for a bilge pump, check to see if it has an Allen grub screw somewhere in the side. As an example of 'customisation', you engine has had the camshaft cut short Richard

The SABB was a surprise to me! Richard

The flywheel will only fit in one location, there's a Woodruff key in the taper. Td'A may be remembering SABB flywheels The bolt that holds the flywheel on will be incredibly tight, you'll probably find it has been undone and done up with a large hammer and chisel in the past. Although crude, this works in the absence of a large socket. There's also a tab washer Free the bolt off and unscrew it about a quarter of an inch (6mm). Then put the gearbox shaft back on - you'll find it won't go all the way home because it sits against the head of the bolt. Tighten the three bolts up and eventually there will be a bang and the flywheel will come off the taper We have new flywheel bolts and tab washers if you want to replace them Richard

We scrapped one because of a cracked block - frost damage. That one looks OK. Nice engine Richard

Technically, it doesn't. It measures straightness, roundness and concentricity. You can infer cylindricity from those figures, not measure it Richard

OFF-TOPIC When working on experimental Stirling engines, we used to get the pistons checked by the metrology department, including cylindricity. They always pointed out, cylindricity is something they couldn't measure. They can measure straightness, they can measure roundness, they can measure concentricity - but they had no 'cylindricity' measuring tool Richard

They're impressive, those blocks. I didn't get them to unpack the crankshafts they had in a box Richard

Did you enjoy Cov Classics? Richard

If that was some time ago, their whitemetalling man has moved to Coventry Classics. Richard

Apologies - you are right. I hadn't read the whole thread

Indeed. If it's a Marine JP you are going to have to take the flywheel off, and when you refit the gear housing you must get the fuel pump timing right Richard

Not really. There are several versions of the JP manual to trap the unwary. The reprints we sell have the plunger pump added at the back Wait 'til you try and work out a part number... Richard

Last time I dealt with a Fuzhou gearbox on one of the Kingfisher engines it had broken the spindle to the oil pump Richard

I'm warning against my idle, untested speculation. From the bits of theory I remember the engine is one mass/spring/damper system with the damping coming from mainly from the engine mounts. This system is going to have a (or more likely many) resonant frequency which is determined by all of those. You cannot change the mass, the springing and damping come from the engine mounts So, in theory, if you've got an engine that's going into resonance at an undesirable cruising speed, you could change the frequency by having different types of mount front and rear On the other hand - I'm speculating idly and R&D do this for a living. Go with the R&D set up Richard
