calling 281/288 experts

i bought a 281 a couple of months ago. i finally finished the carb rebuild and replaced the starter cord. i tuned it this evening with the intention of running it some tomorrow.

it so happened that the oil tank was empty and i heard something rattling around. after removing the covers, starter, handle, and then seperating the upper and lower halves of the saw i realized the noise was coming from inside the oil tank. i thought it might be the pick-up but i found it was a bolt that was loose. it is about 2.5" long with a thin, square head. i found it on the IPL (PN 501 81 57-01) but i don't have any idea what purpose it serves.

can someone tell me what it is for? can i run it without it in place? is it necessary to split the case to put it back (i don't think there is any way to re-install it through the fill hole)? if i have to split it the cases, does it require a case splitter?

the saw seems to oil ok and i don't notice any other problems with it. i was really stoked after i reassembled and tuned it. it sounds very nice.

does anyone have a service manual for this saw?

can you see where it came from in the tank or did it loosen up and wear a hole through the tank and fall in?

it is low and to the back of the tank, near the crank.

it is one of your bar studs,or an old one if both are in the saw.

maybe an old one. both are on the saw. it does look like a bar stud as it is not threaded all the way to the head.

i will check and see if it is the same size as the bar studs.

well i checked and it appears to be a bar stud.

remember the Boy Scout edict: always be prepared......nothing like having an extra bar stud, you never know when you will need one.

thanks kev!!!
