I have a head gasket leak on this machine (It's a Briggs ZZP). It still starts first pull, runs okay, and idles super low, but after it warms up, it starts bubbling from underneath a head bolt and will spray you with some nice hot oil. Nice. Anyway, today I took the head off to see what the issue is. It appears that the head was repaired at some point, I'd say, and I'm guessing that's the problem as that's where the leak is. I was going to try some of that copper spray to see if that does the trick and seals it up. Anyone here tried it before? I know an old-timer told me that they always used aluminum paint and just painted the gasket. I've read that aluminum paint isn't what it used to be (what is?) so I thought I'd try this copper spray stuff that I hear people talk about as it's meant for just this purpose. I figured I'd give it a go and see what happens. If it doesn't work then I guess I'll take the head in to have it machined. I'd like to try the budget friendly option first as this is just one of my many projects on my to-do list, and it does seem to run nicely regardless of the leak (other than it's fairly gutless, likely due to the head gasket leak - but that doesn't really matter as I don't work it, just use it for cruising). Any insight into this copper spray stuff, how well it works, how to use it, etc. As I said, I hear a lot of people swear by it, but I've never tried it.
