Briggs OHV & Vanguard / Re: EC Roller Rocker Installation: 33 vs. 31
« on: July 26, 2014, 04:37:15 pm »
The problem is the tower is to high for the late model heads. EC will make [2] two towers for the different heads. For now just measure the tower and the rocker stud towers and machine the rocker arm tower off, mine needed .206 " milled off.

The rockers are flat across and hit the valve stem real close to the center.
The stupid slide show loads backwards, Duh

Coffee Shop / Re: thumb throttle
« on: July 26, 2014, 04:17:11 pm »Just give him a centrifugal clutch. If anyone has a problem with that they are heartless and don't belong in mower racing.
Just my opinion
You " Rooster " have a way with words, NO other has ?????

What he said. All my mowers have thumb throttles. Will not go back !
Some clubs allow brute clutches and chain drives, so just thumb the throttle and hold on !

Briggs Flathead / Re: 11hp flatty
« on: November 25, 2011, 08:02:02 am »
When the stroke is shorten, the piston dont go all the way to the top of the cylinder, thus, a longer rod has to be installed. Now, the longer rod gives the piston a longer DWELL time at the top and bottom of the cylinder, giving the fuel a longer time to burn and produce more TQ. harder comming out the turns, harder pulling on the strights, thus more Torque...

Briggs OHV & Vanguard / Re: rod length make a diffrence
« on: October 27, 2011, 08:17:20 pm »longer rod makes the piston have more stroke which brings it down in the cylinder farther and closer to the head
I dont think so ??? hmmmm
If the only thing you change is the rod , it wont come to the top , or it falls out of the hole !!
Piston Dwell at the top and at the bottom

« on: October 18, 2011, 05:03:39 pm »What is needed to flip a transaxle i realized that running 18" tires and being 6" in the air is not cool.

YES - Its a other WORLD !
I went to the parts shead and got my old cracked block out. Im looking at it, i think if the carbs were set about 1/2 to 1 " from the block and set to a pitch of 19 degrees in it would be almost stright into the valve, Hmmmm
We run a oppie ever race, sometimes with V-Twinns, cause no real class, BMMA has a class just for oppies, and its a ball, the class stated "oppie - all engine mods allowed", so guess what, yep you guested it, Im going to build the intakes and 2 56 W's and see. I wont to know how much difference it makes, off the corner and how much at the flag .

Is this what your looking for?
here is the thread. http://www.heymow.com/index.php?topic=9786.60
Iv toyed with the idea of 2 56,es on the oppie, and building the intakes for them, short, can you say short, ok
why not 56es the card does good on a 31 cid sov or 28 L heads, so why not on a 23 ci oppie, if you can tune a tillie run you can tune a 56, hmmm well im going to have a need to do this !
