alcohol/methenol

put as much compression in the motor as you can get. not only wil the motor et better round after round but will be much faster. use a top lube, with it you can go week to week racing with outdraining the system. when going over the winter drain, lube the pumps with wd-40 and leave all the lines and tank open. keep the barrel or cans closed all the time and only open them when you need to. seal all the vents off to the fuel tank when not racing and towing. the alcohol will eat the sealing rubber around the lid of the plastic fuel cell so keep an eye on it. keep an eye on the accelerator pump diaphams also. when your oil get milky, drain it into a 5 gal can and let it set and all the alcohol and water will come out of it. you can also heat it out with a turkey deep fryer or 40+ cup coffee maker and use it again and again.
