If you are meaning top towards the rear based off viewing from the side, that's caster.
And, yes, being that you would only be going straight, caster would be beneficial.
12 degrees is a bit extreme..many sports cars run roughly 6 degrees at the most.

Skinny tires offer less ground contact patch, in theory, would be less rolling resistance. In your case, I don't think it would hurt it.

From what I found, the turf smart only comes in sizes that are "large x huge", and not the typical sizes used for racing.

Well, rather then start a new, identical thread, I thought I would resurrect  this as my youngest daughter is now in second grade and doing the same project.

So, If anyone would be willing/interested in sending a postcard to my daughter and her second grade class, please send me a PM, and I will give you the address of where to send it.

Thanks!

Driveline / Re: PEERLESS 688 A: Transaxle stong??

It will "pop" out of gear. It's an issue those transaxles/transmissions had.
2 options are, gear it to run in second, or use a bungee to hold the shift lever into 3rd. I've seen both used.
I don't recall the "why", other than it was a shift fork thing.

Internally the 600 transaxle is quite similar to the 350/400 transmission, except it has the differential and axles.
Prone to popping out of 3rd gear, and due to design/shape, can be a pain to mount. 3/4" axles are also weak and prone to bending.

Briggs OHV & Vanguard / Re: Broken spring on compression release
« on: September 17, 2017, 03:36:55 pm »
Thats really cool and all, but seeing that this is a lawnmower racing forum, and not a "fix my grasscutter" forum, you do not need the release.

Judging by the fact that it has been stated there is a different air filter and exhaust installed, one could assume it is being raced, and not mowing lawn.

There are literally hundreds of Briggs singles being raced across the country that have increased compression, reground cams and the like, all with no release, that are able to start...

But, what do I know?

Your issue isn't the compression release.
Either your starter is dragging and drawing too much amperage, your battery is crap, your cables cannot support the amperage, or your solenoid.

Chassis / Re: 3 or 4 bolt rear hubs

3 bolt hubs are typically used on 6" wheels, whereas 4 bolt hubs are normally found on 8" wheels.

Briggs OHV & Vanguard / Re: Isky intek v twin cam
« on: September 14, 2017, 07:00:22 pm »
Well, it would run.
Would it run better? Probably.
But, when it's all said and done, it's still an Intek..

Might very well be.
Briggs crankshafts are only good for about 1500 though..

Thanks. Do you know up to what rpm the 95 made power to?

It would pull past 6K, not sure how far though, as I limited it to there, as I had a tendency to break crankshafts.
Lots of crankshafts.

I looked in all my usual places, and no grind sheet for that particular cam. I must have tossed them. I still have a few from our last Tecumseh grinds, but thse won't help.

The old Precision Cheetah cam, which was in all reality only good for making power in about a thousand RPM window had specs of

Intake-open @40, Close @80, centerline of 108, 246 duration
Exhaust-open @ 79, Close @40, centerline of 111, 247 duration.
(I found an old sheet on it) They do not provide lobe separation angles..

If memory serves, the #95 had a 106 or 107 centerline, alot more overlap, and lift in the .310" range.
It also made power through a much wider and more useable range.
