Briggs Flathead / Re: Copper Head Gasket
« on: February 13, 2020, 07:05:37 pm »
copper because the bore was so large it made the stock gasket to thin (talking width on top of the block), copper or O ring the head, copper worked just fine.

make your own, buy a .040 piece of copper. cut a old cylinder off a 28 ci briggs, drill through the head bolts and sandwitch the copper between the jug and a piece of plywood and again drill through the head bolt holes, bolt it down, then find a hole saw that fits tight onto the jug, drill from underneath until you are through the copper, file to fit if the saw wasn't quite big enough, don't forget to anneal the new gasket, I'd put a couple of coats of spray copper head gasket spray on it , torque it a couple of times after it heat soaks, have fun

Briggs OHV & Vanguard / Re: ARC Flywheel Balance
« on: November 09, 2016, 05:52:58 pm »
I have never seen a arc flywheel out, this is not to say anything is possible? I have had other things that made the assembly out such as welding on the pulley that attaches to the crank. Yours is off a little over half an ounce? not terrible in my world, the amount of overbalance can vary this much depending on the type of engine, easiest thing is just to balance the complete assembly from flywheel to crank pulley. Just my 2 cents.

Tyler, I balance a lot of single cyl engines, but unless you have chsnged thr rods or pistons to lighter or heavierr units, the balance should be fine on a V twin.

I did mine, I used NPT threads

Briggs OHV & Vanguard / Re: Arc weights vs billet dogbone

Thats it, the only secret is the overbalance, the 3% i mentioned works on smaller engines, the bigger heavier engines like a percent or two more. Good Luck.

Thoughts? I have balanced a ton of these and other single cylinder engines in the past, Horse power wise, go with the weights, it also adds to dependability. You may miss the gear for the track you are on and over rev the engine, it is a ton of weight moving around that crank and I have seen it (along with other people) break. Back to the HP, the reason (besides safety) to run a billet flywheel is to reduce the rotating mass, put one on and instantly you see the HP gain. My Mini's used cranks that were not syncros and I cut them even futher to reduce rotating mass. My cranks weighed less than 80 oz where a syncro crank with the ARC weights were over 125 oz. It gave a similar advantage of another aluminum flywheel on the engine.

The ARC weights are very close in balance, but engines like people are different, some of the cranks from Briggs are auful when it comes to haveing the same amount of weight on both sides and also on the length. So, I have posted on here several times how to check the balance of cranks, but you really need a lathe to even the sides of the crank and do it perfectly. But, you can easily get by if you are not turning over 6K without cutting on the crank and just checking balance with the weights.

And no, I do not balance anymore, time for someone else to step up and learn how to do it.

Longevity and reliability comes to mind. You have to finish before you can win?

Just my 2 cents, Smokey Yunick (arguably one of the best engines builders of all time) once built a small block Chevy and used needle bearings through out the engine, he said it simply started easier and saw no performance gains. A plain bearing (rod or block type) has the greatest surface area of any type of bearing out there. It can withstand the biggest load. Just saying.

Honda and Clone Engines / Re: GX340 smokes

Might also have been the head gasket, the area between the valves and crankcase, kinda hard to see.

In the future simply take a old spark plug, knock pout the guts, add a air fitting and pressurize the engine, if you hear air from the intake valve or exhaust valve or it comes out the crankcase breather, you have found the problem. In this case if you had done  that AND the head gasket was blown, you would have heard air coming out of the oil fill. You might have assumed it was the rings, ?

Chassis / Re: front axel
« on: November 25, 2015, 11:10:59 am »
I used 1 1/4" hexagon stock, then used 5/8" heim joints tightened up to the stock for bearings, the hex gives a nice place to weld the bolt to. By the way, I have the spindle jig and axle jig that I may no longer use if anyone is intrested in it? great scrub angle, works with 8" wide front rims, the Zero Tolerance used them for many wins?

Racing Mower Builds / Re: task force mower
« on: October 19, 2015, 11:23:07 am »
Ok, I'll bite, I think the veiwers are being kind to you. You need a plan before embarking into this world of mower racing, most have evolved into someting far bigger than we were in the past. Todays mowers are super fast, competive and as you know, speed cost money.

Here is what I would do if I were you. Find a racing club near as possible, hang out with them, study the fastest racers, listen to them talking, find the winners and try to duplicate them. Once yu get to their level, then you can advance to make your stuff faster, don't reinvent the wheel.

The welding technique you refer to is gas welding, yes it will make the metal red hot, is it the best way weld, no. Find a friend who knows how to weld and learn. Mig welders are cheap and what I call an idiot welder, anyone can learn quickly.

Attend as many races as you can, figure what your budget, expertise, and skill level will allow you to run.

Lastly, good luck, we need new people racing and there is a wealth of information on here, pick through it.

make the pipe about a foot long, paint it, cut it off a couple of inches past the place it burnt the pain off
Opps! missed the word stock, just put a muffler on it.

Don't run spacers, flow is what makes flatties run, when you make it flow properly you will loose compression, not a big deal.
