plug and wash reading.. tuning help

Actually new plugs make reading them much harder. It helps if they have a few miles on them. Reading the wash can be difficult to do. I have a borescope and you still can't see the whole piston with the one I have. I have used a mini flashlight with a 4" long flexible tip that is the most helpful, it can be inserted into the plug hole to help light up the piston.

I use THIS bore scope from Snap-On. A little pricey, but you will find that you use it for a ton of other stuff too. It has a magnet tip for the camera head as well so when you find that nut under the engine you can surf the camera to it and snap, you got it. Has a 90* head/mirror to look into tough to read ports or valve seats. There is a video out RCA jack so you can easily plug it into your video camera and save a video image of the wash to take back to your "piston wash" expert buddies to look at. Not that I ever had to do that. lol. You can also look right up the Y-Pipe to see piston skirt wear or ring land issues on your Dragon, again, not that I ever had to do that. lol. lol...........sorry, not funny.

This is a great tool to have. Once you've had it for a while you wonder how you got by without it. Get 5 buddies to throw in $100 a piece if money is tight and share it. There may be other brands out there for cheaper too, but I know the Snap-On works great and will stand behind it if you hit the electric start with it down the hole. Not that I ever did that.. Good luck. EW

I have a hard time reading a plug and piston that is on a turbo sled with race gas. They always look lean to me.
