Going to tear them down

[Zep71]

after reading a thread Jam Racing 1 turned me onto about sealing your nitro motors. i have decided to tear all my motors down again and reseal them. even ones that are not in use. i have had some tuning issues and this should help i hope. thanks Jam Racing 1

Sometimes the screws that hold the head on are difficult to remove. I just put mine on the woodstove for about 5 minutes, then the screws crack loose with no problem. You can also use a heat gun or oven. Just have some leather gloves on hand because the engine will be too hot to handle!
