Two motors couple different issues. <br /><br />My F60 is hard to start often requiring 5 to 6 attempts to start before it finally kicks off. When it does start it runs a tad rough before smooting out.<br /><br />My T8 starts Ok usually on the second try, but it smokes quite a bit. Also at lowest RPMs it runs a tad rough causing the motor to shake. This leads to an anoying squeek that I think is caused by the control cable bracket and the control cable rubbing due to the shaking of the motor. Come up a 100 rpms or so and it goes away - the squeek that is, but it smokes more than a 4 stroke should.<br /><br />Gas has stabil in it and Ring free, primer bulbs always squeezed till they are hard, do not run gas out of motor at the end of the day, and neither motor burns any crankcase oil, T8 has 32 hours and the F60 has 14, plugs are still original.<br /><br />Will a tune up solve these problems?
