Thanks! I did try to solder up some of the holes in the tank, but only one stopped leaking. It takes quite a while to do but I think it will work if I go over them again. Yeah the rings could be seized, when the engine is cold there is reasonable compression but when it's been running for a while there isn't very much compression.

Sounds like we're on the edge of another teardown here!  

The fill and the cap for that tank look really rough.  I can't believe it works, but I think the vibration from the engine would pop that cap off pretty quickly.

Nah, it runs alright so I don't think I'm going to bother taking it apart unless the compression gets that bad it won't run. Yeah, I'm not too sure about the cap but we'll see.

So I tried to solder up the holes, but it doesn't work. Tank still leaks. So I'm going to try some metal tank repair putty like these to try and seal the tank up.
My soldering iron's not very good either so that didn't help when trying to plug the holes.

I guess it's time to go the epoxy route.  It's cool to see a product specifically for this.

Fixed the link. Yeah I hope the epoxy will do the trick. The tank does have some rust in it, but I will clean it out as best as I can. I'm not going to put too much money into this tank cuz it might not work.

Did some research into the engine on this water pump, turns out it is a 3hp. Must be pretty rare with the updraft carb and rope start only, which is surely quite late for a 1975 model. Found a Briggs 3hp & Alcon Water pump identical to mine for sale on ebay starting at £30. It is in better condition than mine though and runs. Found a 3hp Briggs with updraft carb for sale for £40 which is too much, especially as it doesn't run. Also found a job lot of Briggs', 2 have the updraft carb and separate tank same as mine, and the other is a carb & tank setup with what looks like an Alcon pump.

Just some of my internet findings if anyone's interested Smile

So ordered up the tank repair kit. Should be here in the next couple of days.

I'm trying to get the pressure washer pump off the Honda GX200 that was removed from the frame that the water pump is now on, but it's stuck on. Is there anything I'm missing, like a setscrew or something?

I struggled taking one of those off an engine at work.  Basically I really had to fight with prybars to get it off once I removed the four bolts holding the pump on.

Yeah I'll probably end up doing that, haha. There is a screw in plug on the pump where the engine shaft should be so I might take that off and see if there's anything holding it on. I want to check before I force it off and break something.

So the tank repair kit turned up today. Patched up the tank, doesn't look great but hopefully it holds. I can sand it once it's cured. The instructions says it cures within 1 hour, but I'm going to let it sit overnight and leak test it tomorrow.
