I actually have quite a bit of experience with carbs but keep hearing "seafoam...SEAFOAM" so much so that I got a second bottle yet it really hasn't fixed any thing. I really cant say anything very good about the product.Well now you will have to actually do some work. Take the carb off, completely disassemble it, clean each part with carb cleaner and then reassemble. Then bolt it back on.
If you have limited experience with carbs, take photos as you are disassembling it so you know how it goes back together.
