before you buy a boroscope, make sure it will fit in the hole you are going through. I have used a boroscope and they are great, but sometimes they are hard to see because everything is so close. you will also need a magnet to fit somewhere at the same time as the scope. try to get one with a strong magnet and a flexible handle. some of them have a light in the magnet. I use that one quite a bit over the one without the magnet (ya, I have dropsey too. common ailment of diy'ers). hopefully you don't end up taking the intake off. i f you,though, you would be able to clean the heat riser runner under the carb in the intake manifold. there has to be a bonus somewhere here. just remember, don't let your carb get upside down or some of those "undesirables" from the water/debris episode could end up in places they shouldn't.
