Indeed I am afraid of that to
Purchased the sled blown up so that I could learn how to rebuild a motor! Getting much more than I was looking for, will be an expert in the end LAMO!!!!
But again all the expertise form all the guys is is great!!!
Honestly, its about the only way (and best way) to learn.
You can read all day on hear and learn some things, but once you actually do it, its in your brain for good.
And, it becomes easier and quicker every time you have to do it again.
Its a good feeling to be able to do this work yourself with confidence!

Yup so true!
So I removed all the cylinders, sucked all the liquid from the base and added water in the coolant system, bringing the water level in the water jacket of the base up to base gasket ( 1/8 below).
I rolled the Primary by hand to work the water pump, to see if water would seep through... it did but not sure if if was only liquid dripping from the crank that was soaked.... so shop vac dry again and now letting it seat for few hours to see if some water will rise/accumulate in the bottom of the base...

I was doing so troubleshooting this afternoon and and searching on here.... I found one of my old post and remembered that their is a weeping hole in the base under the water pump shaft.
when posted on the forum question about that hole, we came to conclusion that it was for the purpose of seeing if the seal was done... coolant would leak from there...
So If my base fills of coolant by the water pumps seal, I should see leaking through that hole?!?!? but by the amount of coolant that I shop vac in the base I would have expected lots of coolant in the bottom of the sled, belly pan... but pretty close to none.....

While it was running,
1. Was it firing ok.
2. Was there a sweet smell in the smoke.
3. Are there any "wash" spots where hot fluid has cleaned away any gunk.

Hi,
When I first started it after the rebuilt it fired properly but right away huge white smoke started coming out of the exhaust and every 10 seconds or so their would be a missfire. Now, before I reopened the engine, it would not fire but understandable with all the coolant going in.
not sure of the smell of the smoke but definitely choke you and make your eyes cry!!!!very dense.
I did not have the opportunity to make it run long enough so that the coolant have time to warm up. But before putting the engine back together I poured some oil down in the base so that crank would be lube for initial start. Now I did drained with a shop vac, but when I look down the base with a flash light and at the crankshaft, now sign of oil at all. (not sure if this is what you mean by, gunk away)

This is making no sense to me. The water pump shaft is between the MAG on CTR cylinder. the CTR and PTO are puking all the coolant. how is that happening?

Good point! (in my little knowledge so far)
I filled with water yesterday and let it sit, will wait 24 hrs to see if any seeping. The only I have found visually so far is that some of the bolts holding down the cylinders seemed a bit loose. (maybe just me being stressed of everything now lol )
But again if it was a faulty gasket/ not torq enough, i assume it would leak outside to, not only inside...
Going to canadian tire looking for that copper spray. Unless you guys come up with something to investigate or test, I will put it back together, fill coolant and see it it does it again....
Shouldnt NEED copper spray. Those metal gaskets are reusable, and seldom leak in my experience.
If those cylinders were loose enough, could cause it, but its alot of coolant.
I still bet on water pump issue. If its not sitting on perfectly level ground, it could be dumping coolant in the case, and running in that direction, then getting thrown out.

Was there just tons and tons and tons of white smoke? Much whiter & denser than normal 2 stroke smoke. Or was it pretty much like a normal start-up?
did anyone rinse out the pipes with gas or varsol? pipes and silencer might have had some in them from when it poped.
You guys watch the video he posted ?
Lots of coolant currently going through motor while running.

ohhh shit no!!! Mucho white and dense.... Impossible to see through at some point. And every time I attempt to fire the engine when I remove the plugs, they are full of that white/grey sludge.

Hi!
I did not rinse with gas of varsol, but every time I make a new attempt to fire the engine I remove the pipe after and always dump the coolant from it and let the pipe sit up side down for a day. So when I put it back on there might still be a few drops in it but nothing like half a cup.

thats what I changed in the first pic and in the second pic what it looked like when it was put together..... I will remove the cover from the water pump today and have a look in there.
third pic is the weeping hole under the water pump
As I stated, I think it's the water pump seal. Another thought, could you assemble the head onto the 3 cylinders with the head gasket, torque down to spec, flip over and fill coolant passages with water to see if anything weeps by the head gasket? I realize the coolant wouldn't be pressurized but could help eliminate that area as a source for the leak?

Sure can definitely try it! I will come back with the result.

UPDATE:

Ive put the head and cylinders together and torq to approx 35, flipped it upside down and filled with water...now waiting.
took a few pics and a clip of the seal. To my knowledge all seem ok... appear to be seating properly against the body of the base and to the feeling as well, dont see any damage....

ok so after close to 24 hours of having the head mounted on the cylinders upside down with coolant channel full of water, no leaks.
