That is a good idea.
Except for the loading it on trailer part, driving up ramps is rarely safe.

It is also dangerous to run it open.
No one else is expecting it, if you go into a corner and actually lift the left rear, you will slow dramatically or even stop.
In tight racing like IMOW, or any class for that matter, you are more than likely going to get smacked in the rear!

wish i could get mine to run right .... earlier i did a carb rebuild and it ran like crab and backfired so hard it snapped the fuel pump bolt and now i dont have the money to get a new carb plus i dont know if i wanna fix it i made a mistake i think buying the motor
If its back -firing you have a timing issue.

Just another "off the line trick"
Mount your kill switch in a hinge, mount your start button under the hinge.
When you plug your tether into the kill switch, it pushes down on start button  Wink

Build a spring loaded catch for your clutch, that holds it in.
Then you can plug in and start mower, still in gear, while getting on it...by the time your in the seat the engine is running and you can pop the clutch and go!

The little rubber kill switches - yes drill a hole in them, also put a small screw in the rubber "button" inside the tether part that pushes down on the switch to keep it from wearing out Wink

Oh, I'm still going to the races, just no racing.  It's a family reunion kind of thing for me...I'll make myself a crash dummy suit or something, wave a video camera around a bit, help people with their mowers, whatever I can do, LOL!

I'll be glad to meet you.  smile
Jeff - You'd make the best Crew Chief mower racing has ever had!
Where ever we race, on a mower or not, the race will be better if your there!

Personally something is wrong soimewhere some how. I have run nothing but briggs pistons for years use em other motors too. Turn em 7000 to 9500 everytime they hot the track and never broke a single one. NOW I have seen them break there but they were kissing the head or hitting an improperly cut copper gasket. Somethis causing it for everyone of yours to do that. You have not gotten that many bad pistons in a row. And William, a briggs piston is good sure there is after market out there Ron makes em with the rods too. hard to get ahold of him though. But like I said I run them hard and never had any issues along with 1000's others.
I have run lots of them too George, have some brand new ones sitting there waiting on next engine....but It chaps my tailfeathers to pay so much for them when for very little more you can get a better piece! Problem I have is finding rods to match them.

Can you guys give me  some leads on upgrading the brakes and steering? Does anyone make anything or is there a DIY out there??

This is what I have gathered so far,

< 4000 RPM, oiling mods are a good idea
> 4000 RPM, flywheel and oiling mods are a must
> 5000 ROM, flywheel, oiling mods, and pistons/rods are a must

Sound about right?

Why run these pistons? They are not suitable for racing. They are prone to failure, from several differant causes. The service life is short and if the coating is damaged...which is  very easy to do...wil eventually gall itself to death in the cylinder. Now these pistons are not even close to cheap...why not spend just a few dollars more for a good quality aftermarket piston?    You will enjoy a much longer service life...and a performance advantage too.
I agree with Will on this one....(SHHHHHHH, don't tell him)

Bought new, the Briggs piston IS expensive! They are not a "performance" part and not held to the same manufacturing tolerances of a performance part! We are putting much higher stress on the parts than they were designed for.

I don't think it is so much that some people got some "bad" ones as it is that some people like Paul got some "Good" ones!
Small engine mechanics - How many engines have you seen with "bad" pistons? rarely! For their intended purpose, they work great!

WIth all that said - If your cracking one side of the wrist pin holes - then one of 2 things is happening - one side is weaker, or you are not loading them evenly?
Is the bore square to the crank?
Is the bore round?
How much end gap on rings?
15  Engine Help / Briggs Flathead / Re: Govenor issues on: April 18, 2013, 07:33:04 AM

Put the governor back on it, hook it up..adjust it??
Lol, not real sure what you are asking...do you know what/where the governor should be?
