that would be my recommendations


and DO NOT break the engine in blubbering rich , thats even worse then grossly over lean , well almost

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 ',
Monty
