I challenge you to do this on your Briggs and tell me the result.
This has been covered (in these forums) over the last couple years and no positive results have been achieved to date.
If this mod did do anything, everyone would have done it long before now...including the manufacturers (and myself).

After reading that nonsense. It lists the cam turn in degrees. Degrees are quite smaller than teeth. In saying this it is not worth your time to go a tooth or so forward or backwards because you cannot accurately tune it.
I will try to find a 5 hp briggs and then me and my bud wolfie are gona try to build it up for cheep by any means possible. he has one on a roto tiller but we cant find it we have to go through about 10 different trailers to figure out which one its in. he knows he has one but he forgets which one it is. if its not in one of them its back in the one of the sheds in the woods. woops im rambling on again. well i will try it out eventualy when we find the **** thing.

I explained the problem with this procedure (at some length) with another poster about a year ago.
I really don't feel like re-writing it at this point.
If I can locate it, I will re-post here.

so this is a different questions but... I accidentaly ordered a raptor 1 rod rather then 3. Is it still a billet rod, or is it the same thing ive got in my flat head now?

Raptor 1 rod is a 3hp rod.

I believe the only real effective way to get better results from a stock cam is twisting where you can vary intake/exhaust lobe separately apposed to advancing/retarding both lobes.
Not adviseable. These are precision machined parts and unless you can make both lobes exact I would'nt even attempt destroying the part with a welder. Reguardless without the proper tools the ramp on the lobes would differ and the cam would also be very shaky.
You don't want unbalanced parts in you engine unless you really hate it. Lol

a toothpick? Ive seen metal parts wear away, and i mean completely away. Im pretty sure a toothpick would just compress and disappear. I dont think a small wooden toothpick is the best thing for a shim. ANYWAY, are there any woodruf keys that advance the timing for a 5hp?
you'd be surprized I've been using a tooth pick on my honda motor for a long time. you really only need something to hold it in place until you can get the flywheel torqued back down.
Never had any problems with it slipping out of time, plus a wooden shim will not damage the key way if it were to slip.
But your right though if you can get an offset key that is the better solution. I'm pretty cheap when it comes to somethings.
Oh and yes they do make offset keys I've seen them before, i might start using them just to be proper...LOL

yea i guess thats true, the flywheel being tightened will help. Do you know where to get an advance key?
