Hey Monty, much love on the data! A few questions on terminology..

1) comp heat?
2) primed the system?
3) Cleaning the engine out?
4) heat cover?
5) heat cycles
6) hest cycles
7) air filter media

heat engine to 190-210° , i prefer comp heat , start it after you have primed the system by opening carb and blowing into the exhaust pressure line until no more air bubbles go through line , dont be afraid to rev it up a lil , keep it running , you will have to lean the needles a little and turn the idle up a touch , use a quality temp probe such as exergen brand (important) tune as to maintain a constant temp between 190-210° , unplug comp heat and let idle for 5 min , engine will be a little erratic at first but will settle in after a bit , clear the engine out every minute or so .

repeat this process three times on the bench with head covered , make to sure to pull head cover off during cool downs , place piston in a free movement area (some refer to this as BDC)


after 3 x 5 min heat cycles do 3 x 10min heat cycles on the ground in the car at 190-210° , head uncovered (unless ambient temp is below 50°) and run around gently , dont baby it but do not rod on it , above all refrain from blipping the throttle as it is referred to .

after 3 x 10 min heat cycles do 3 x 30 min. hest cycles , the last one of these can even be done on the track but remember to keep a conservative tune , do not rod the engine all the way down the straights , check temps frequently .


from most novarossi engines i would not expect miracles within the first gallon of fuel but the engine will perform well enough to race with , at some point the engine will change tune and go really rich on ya and tune will keep changing for a period of 4-5 tanks of fuel , i call this "dropping the nuts"


when you take the time to take care of your novarossi based engine it will provide you with a long life of trouble free running !!!


remember to make sure your air filter is always up to snuff!!!!

there are a few companies that sell air filter media that i wouldnt use if they paid me , one great bargain and excellent material is answer rc , great filter media , when used in conjuction with the awesome kyosho air filter oil , your filters will stay dirt free and protect your valuable engine !!!

happy motorin ',
