Hi guys, I changed the oil and impeller on my 40 hp autolube yammy yesterday (aprox 10-15 yrs old). However, on putting the g/box back on it slips horrendously when putting it into gear.<br />I assume I have to adjust te length of the connecting rod. I assume that they are counter rotating threads and as such that would take loads of playing to set up. <br /><br />Has anyone got any hot hints on this?<br /><br />Many thanks in advance.
