I thank you all for your comments. Here is why I've asked this question. I will be actually using my cubs this Summer to mow my lawn rather than just toying around with them HAHAHA! This being said I'll be putting some stress on the old engines and just want to do what I can to keep them in shape. I don't have the skill set to rebuild an engine and have to take all the precautions I can to keep these engines running. Rebuilding carbs, no problem now. I have never taken the head off an engine but I'm pretty sure I can take care of that with some help from you folks :-) Pretty much, most things outside of the engine I'm ok with and feel that I can take care of but once that engine needs to be rebuilt I'm going to be in trouble. I also have that Marvel Mystery Oil here that I think has helped one of my engines come a bit back to life but I do have to agree with one of the posts, if these chemicals break down the gunk, where does the gunk go?

So on a side note, any chance we could put together a thread that links to threads around here on tips on how to maintain your engine? I know all these nuggets of gold live in hear but unless you know what you're looking for it's hard to find. I watched a video on setting your valves. How would you know when it was time to mess around with them? You folks have got me a lot more confident to work on my tractor but I'm still lacking the knowledge of when to mess with something :-)

Anyway, I want to thank you all again for your input on this Seafoam topic and it really seems like it's a personal taste thing and folks all have their own experiences with the product.
