Driveline / Disc Brake
« on: October 06, 2020, 05:41:53 pm »
Peerless 800 series transmission. Where do you put the brake rotor. There isn't enough room on the axle between the tire rim and the transmission case.
Thank You

Driveline / To shift or not
« on: March 25, 2019, 12:12:15 pm »
I posted this in the Drag section and had 186 views, but no answers. Hoping someone could help here.
I have a Peerless 800 series transmission and will use it in a drag mower.
My question is what gear do the drag mowers start in, and do they shift more than once?
Thank You

Driveline / Peerless 800 axle
« on: November 05, 2018, 06:36:22 pm »
My Peerless 800 series transaxle has only 4 inches of axle sticking out of each side of the transmission. I have already locked the axles. I have heard there is a longer axle available, but would like to use what I have. Will a deep off set rim extend the width enough to make it useable for racing? Maybe CP or CPR.

Briggs Flathead / Walbro 56 carb
« on: October 20, 2017, 03:23:31 pm »
Went through my carb parts box and found I have two Walbro 56 carbs and one 48. I also have the EC high end needle kit. Removed the choke butterfly and shaft. Checked out the Walbro 56 search function and found several comments on this carb, but most answers are several years old. EC declined to comment on how much to drill out the tube when you add the new needle. Some one suggested 5/64th. Any new information on mods for this carb?
Thanks

I posted this in the drag mower section, but want to get as many ideas as I can.
Is there any advantage to running skinny tires on the front of a drag mower?
See any safety issues with this?

Chassis / King Pin Angle
« on: September 25, 2017, 11:38:11 am »
I posted this in the drag mower section, but want to get as many opinions as I can.
Thanks for the indulgence.
Should the king pin on front axle be slanted towards the rear for a straight line racing mower?
I think my A/P is set at 12 degrees.
Any advantage in skinny tires on front for drag mower?

Drag Mowers / King Pin Slant
« on: September 25, 2017, 11:12:30 am »
On mowers set up for straight line racing only, do you still slant the front axle king pin towards the back? I think my A/P mower is 12 degrees.
Is there any advantage to running skinny tires on the front of a drag mower?

Briggs OHV & Vanguard / Valve lash specs
« on: August 27, 2017, 04:11:52 pm »
Valve lash specs for the Briggs OHV 28ci seem to run all over the place.
I have seen recommendations of intake: .oo4 and .003. exhaust: .006..004
A small engine mechanic told me he sets both at .003
This is a stock motor. What works for you guys?
Thanks in advance
