Wow that's alot of porosity in those welds I've welded a fair few cases scooter and m/c I always dipped mine in solvent first then hot washed them if I had blow holes I'd cut them out and redo them
I'll admit I've never put that much weld on one but actually as you put more on providing the first pass has been cleaned up it should do a better job with each pass of weld

Exactly! I'm guessing your only consolation is you only paid £180 and not the £380 I was quoted.

Honestly mine was fine. Ignore the nay-saying. Just fill the blow holes with jb weld or something and all will be cool.

yes i agree, youve done the right thing using jb weld to fill them, i use yambond or similar on gaskets or where there isnt a gasket without any problems, and like you say a leak down test will be well worth doing, keep the pics coming, some good work there, ive got a few welding flaws on my 290 rotax conversion and thats going to get the jb weld treatment as well,

Well if its of any help, I've used JB Weld on my Sprinter Crankcase, where, trying to weld anymore in the crank area would just cause more porosity, and its been fine. Its a crankcase that's had a fair bit of welding btw.............

Had a case coverted about a year ago. If you want the welding cleaned up / reshaped they will do this for you (or would when mine was done) at extra cost. Personally i didnt bother as it aint visible when engines in anyway. There were a couple of tiny bubble holes on gasket face but nothing that was going to cause a problem and a leak test confirmed this. Good luck with your build.
