MS-362 Spark Arrestor Screw Lost -- What is the correct replacement?

[kalevan]

The spark arrestor looks like this:

Can someone perhaps look-up the part number for me in a manual? or the on-line service docs?
My sleuthing turned up 4.2x9.5 self-tapping screw. (sheet-metal screw?)
Is that the right description?
Does it have a T-27 head?  Philips? Slot-head?
Does it show that the screen is installed with a lock-washer too?
I don't want to use any old junk-box screw due to the risk of ruining the threads.
(I'm surprised spark arrestor screens kits aren't sold With the replacement screw...)

Can anyone suggest a source for a service or parts manual? Can it be downloaded from anywhere?

No help with your problem,I suppose you are not close to a dealer to go in and ask them?

Welcome to the forum.

On my 361, it's just a slotted head sheet metal screw. If I lost mine, I would just look for something that would work from "the junk parts drawer" that would fit. It needs to be short, just long enough to engage the sheet metal, not that "slightly too long" is going to hurt anything (at least on my 361). If you're slightly oversize, well, now you have bigger threads, and a screw to match!

That said, in my 361 parts list, it's described as

part number 9099 021 0810 Self-tapping screw 4.2x9.5

It's probably no more than $50 at the dealers. :D
