My Posts This: Topic Forum | in theory the metal ones are made with more precision but just run the stock fan and save your money. to cool off the engine a bit open up the main needle valve a couple of clicks. On the TT-39 you may need to open it up 4-5 click.
Also, maybe look into the low end needle mod. The TT-39 and 50 can both benefit from this.
