I got a Trinity Platinum A. Drake in a deal for a Truggy. The engine maybe has 12 tanks on it. I have no idea how to tune this engine. I'm not even sure what the base settings are. I took it out and ran it today it ran fine. I tuned it to be rich so not to mess it up. I didn't get more than to tanks through her before I discovered the front diff needs rebuilding. Brought it home took the head off and the piston is clean and shiny still. It gets stuck at TDC so I know it's a fresh engne. Just need some help and some suggestions. It sure sounds mean as hell.
