RE: Is the K&B .65 a good engine? I found a new one in the box.
LIKE ANYTHING IT DEPENDS ON WHO YOU ASK ~ IT IS A LOWER END OF THE LINE ENGINE AND AS SUCH WERE/ARE INEXPENXIVE TO BUY ~ HAVE MANY .45 AND .65 AND I PUT A LOT OF HOURS ON THEM ALL EACH SUMMER IN CLUB TRAINERS AND FUN PLANES AND RUN RICH THEY SEEM TO GO ON FOREVER. I NEVER HAD TROUBLE WITH THE O RINGS OR CARB SETTING BUT A FEW OTHERS HAVE. ALSO HAVE TO BE CAREFULL NOT TO STRIP THE THREADS IN THE MUFFLER BUT IF YOU DO CAN SLIP IN A NUT AND LOCK WASHER. EASY STARTING AND GOOD RUNNING ENGINES IN MY EXPERIENCE AND WE PUT HUNDREDS OF HOURS ON THEM EACH SUMMER TRAINING. WE PREFER A 13X6 MASTER PROP ON THE .65'S. FOR WHAT IT IS WORTH! AL
