well this is whats going on.. I got a toro 21 mower with a kawi on it and the other day I took the outer cover off of it to clean under it. Well when I put it back and stared it...well it stared to make a squeking sound. I checked to oil just to make sure and it need just a small amount and its still making it. The mower starts fine but then it start to make that sound its not loud but it was never there before. Did i put to much a$$ on the bolts or what ? Let me know what yall think and by the way the mower is not new it has some age.
