Very informative review . That's s handy tip adding a drop of meths to the solid fuel. Yes very good review.

This vid was well done and takes about what you were doing witch helps us hobby people unlike other vids were they just try to force the wheels instead of working the water out of the pistons,.

I've built two of these with no issues. I have also made all the updates, and have changed over to meths firing.

Nice demonstration of the MSS loco! Neat little things they are too, I see the Merioneth And Lanticilly Rail Traction Co. Ltd. might be getting one ;)

its a very nice vido reading about the praming plodlems is ver starge because when I go mine the boiler never had that the engine ran like clockwork

awesome. I'd love to built one of those kits but I reckon, knowing my luck, it'll just go bang haha

Make sure you flush out your boiler. I use a 50%/50% water/vinegar solution to about 2/3rds boiler full. Heat this up towards the boil with the safety valve removed. Lots of agitation and let it cool down. Then flush out the boiler several times with cold water until you get no signs of any deposits. Gets rid of all the excess solder paste, etc. that causes your priming problem. My factory built MSS Saddle tank was really bad for priming when I first started running it.

How well would it scale up to 2 1/2 or 3 1/2 inch? I had one always wished it was bigger. Mine was a kit from Dream Steam bought in bits for me in Australia...

To fix the whistle problem on the kit version you need to shorten the screws used to hold the cab back retaining clip to the cab roof - MSS have supplied the wrong length screws. Is the clip on the factory built version held on by screws & nuts, or rivets? Rivets may need to be carefully filed down. The steam leak could be due to some tightness with the pistons/piston rods. Try rotating the piston rods by 180 degrees and give it some more running in going backwards.

i dont understand why my MSS loco ran so terribly. It never worked right and even after spending more than it actually cost on repairs and upgrades it still sucks

Was that a MSS kit or a factory built MSS? And how old is it as MSS quality control seems to have dropped in recent years?

Unfortunately, my new ready-built one was an excessive primer. It dumped half of it's boiler contents in 3 seconds flat. Ah, well. It will settle in, soon.

No D in the word locomotive 😀

it isnt gonna run :(
