i have a 2-stroke 95 polaris 400l and last week or so wont start unless i put a new plug in it wondering if i should change the injector oil. was using formula one (canadian tire) just bought some Interceptor Synthetic 2-Cycle Oil amsoil , it says it reduces smoking and gunk and fouling, and says that its recommended for polaris, yamaha , ect atvs? any thoughts

 

Most 2-stoke injector oil ok,but dont mix brands can cause lubrication problem! If pump set correctly,check needle and seat/replace if fouling plugs. Also compression, dirty air filter can contribute. If changing oil brand,drain oil tank and bleed pump. Not familiar with formula one?, havent used 2-stroke amsoil,but have used their 4 stroke oil. Our old rating on oil was TCW3 on atv's and watercraft.
