Make sure you read all the instructions. I used a buddies flux core welder a few years ago. Wouldn't weld worth a damn! I looked up the manual online and found when using flux fire the polarity of the welder was supposed to be reversed from how my buddy was using it! After I switched it, all was ok.

That is correct. Flux core wire does use opposite polarity from solid wire. Polarity DOES affect a weld.


Incidentally, the only way to learn to weld is to be taught by someone who knows how, and to actually do it. This is one of those things where practice does make you much better..... if you understand how to do it.

Hey Tim, if you have not put the thing back together yet could you let me know what length the bolts are that bolt the cradle to the oil pan? Of the three left on mine, two are different lengths and one looks to be non original. Looks to me like they should be 1".

Thanks,

David

Good idea to chase the threads in the pan, then put a too long of a bolt in there
and measure, allowing for lock washer, and thickness of the iso rails.
Too short and they will strip, too long and you will break into pan.

Yeah, that's what I did, looks like a 1 1/8" bolt would be perfect so either a 1" or a 1 1/4 with an extra washer or two. Probably better with the 1" just to be safe. The threads for the missing bolt seem a bit sloppy, thinking about heli-coiling that one, or maybe all 4, what do you think ol' George?

1" - yeah I would be careful going longer especially on aluminum pans. I'm already replacing one of those with cast iron. I'm sticking with 1" and a lock washer I think.

So what's goin on timbo2, you getting that thing back together? Just wondering what your using for motor mounts.

Yep getting it back together slowly but surely.

I'm using solid mounts from Jeff in PA.

Got the engine back in yesterday and have been cleaning up the piston and valves, adjusted the valve clearance.

Waiting on a new pto switch and need to clean up some wiring, flatten the cylinder head. Then clean the carb real good, this thing was set super rich when I got it a few weeks ago. the high speed needle was set out about 4 turns vs. 1.25 spec. lots of carbon to clean.

Looks like you got it cleaned up real good. Nice work. How 'bout the 3 pin driver, staying stock or going with a solid one?

It's a hydro 1650, technically a 1450 that got a k341 in 1990. Could be quite the machine before long.
