    My 362C-M came home today and I am about to put the dual spike kit on.

    But... I forgot the 362 doesn't have a pre drilled Clutch cover. So what would your advise be? I am gonna drill from the inside, but should I put tape over where the bit will come through? What kind? I don't want to chip the paint ;)

    This shows that the new kit is the same size, but adds a larger bottom tooth and a chain catch.. Also eliminates the cheap stamped stock spike/dog

    I'm glad you posted. I was wondering the same thing for mine that I'll hopefully install this weekend.

    well if I read this right then I would carefully mark where you want your holes on the backside and drill with an undersize bit from again the backside and then drill to size from the outside(painted) side. debur with countersink or what-have-you. hope this helps.

    That would have probably worked great. But I was getting impatient and couldn't wait anymore. . :)



    There is a hole inside the cover. Where they normally would be, and the instructions show to use a 7/32 bit and just drill from the inside, to the outside. But I was worried about chipping.

    I ended up using the next size down (3/16) bit, because the 7/32 seemed like it was gonna be sloppy. I put masking tape over where the bit was gonna exit. Ran the drill at a fast speed, but light pressure.

    Worked great..

    Lukem, your gonna be shocked at the sheer amount of chips that are created when you drill that cover out. :)

    I see I'm too late, but this is what I was going to post:

    I'm going to differ with this. If you drill a small hole first then it will have to be much smaller than the final hole, or else it will be liable to make the larger drill act like a screw instead of a drill, biting in too deeply and trying to thread itself through the thin clutch cover material. This can cause all sorts of havoc, from diverting the drill away from where you wanted it, to chipping out a rough hole or even cracking the cover material, depending on how powerful the drill is and how fast it's turning.

    I would probably just centerpunch the hole locations on the outside and then immediately use the correct drill size in a handheld VS drill, lubed with a nice puddle of oil, taking it very slow and easy as the bit began to emerge on the inside of the cover. I'd finish up with a couple of turns of a countersink on each side as pigpen suggested.

    Looks great. Was the 3/16" a good fit or should I go with 7/32"? Waiting somewhat patiently on the full report.

    when I do a pilot hole I usually drill it with a bit slightly larger than the web of the final size bit. but like I say, its not how you get there its the finished product that matters.

    3/16" worked, but was a little tight. So once through, I just spun the drill at a high speed and kinda took some off the sides (not wobbling. But rather pushing against the sides, all the way around).

    But it looks great and I just came in from running it. I only cut about 7 cookies, Dayuum!! This thing Hauls the mail!! No doubt my favorite and I don't regret selling the 036 one bit. I honestly can't believe where it's all coming from. And that added muffler port makes it sound awesome. I had a pretty big hole in the stock outlet already, but this saw obviously benefits from a lot of exhaust outlet! It's a screamer. No doubt would take a stock 70 cc saw. No doubt..

    But the 7/32" would probably be a one and done deal.

    This has to be the biggest gain in performance on a stock saw that I have run. It is UNREAL how strong it is..

    Glad you got the dog mounted. IMHO, Jon1270 provided the best method.

    I would say I'd like to run it....but I fear it would cost me $300...plus shipping.

    Out of every saw I have had stock and ported.. This saw takes the cake.

    It would be money well spent.

    Anyone who is close enough to come run it? Should come run it. It is an amazing feat for a 362. I HATED the 361 and OE 362. But the new 362C-M is a Monster..

    And that is a pretty chitty chain (Forester). A good chain and this thing will be like a light sabre!! :thumbs:

    I forgot to answer your question earlier.

    It's a chain catch. If your saw throws a chain? It won't bunch up under the clutch cover and possibly crack it.
