RE: New mcd cy motor tuning trouble(gas tank)!
The buggy looks nice.
A few tips for you though - replace the 24 & 25 teeth plastic gears with the 23 & 26 teeth steel ones and cut out most of the front side windows on the bodyshell. If you race or use the buggy for long periods I would recommend cutting out all of the four side windows and drilling holes in the front window as well - your engine will run alot cooler as a result of this.
