I know I've already posted this topic but I really need help with my clutch problem. Sometimes when it's in 1st and I pull in the clutch and kick it over it will jump like the clutch isn't pulled in. And when it starts in nuetral and I click it into 1st it will jump and sometimes stall right out. Does the clutch simply need adjusted or do I need some new parts for the clutch? Also the guy before me ran a low grade automotive oil with friction modifiers in it. What could that have done? And I'm running 10w-30 and it's about 5F up here. Should I switch to 10w-40?
