1  Engine Help / Briggs OHV & Vanguard / Re: What oil on: October 29, 2014, 09:50:24 AM
Brad Penn Grade 1 racing oil in 10w-30 is what i use.  You may not have a failure using other oils, but a high performance motor oil like Brad Penn has anti wear additives and high Zinc (ZDDP) levels and will give added protection to all moving parts, especially the camshaft. I've seen less than .001" wear on the cam lobes after two seasons of racing turning 9,000 rpm+ and high spring pressure levels.  If you can afford a $3000-$5000 racing engine, you should be able to afford a good racing oil.

Copper is one of the few metals that anneals differently. I still just let my gaskets heat/cool naturally in the engine and re-torque the heads in cycles.

Here is a link to the info George quoted,

One carb sold, one left!

Owen, check with the place you buy your gaskets from. Some copper heads gaskets are already annealed when you buy them, and some companies don't recommend annealing their gaskets due to the engines repeated heating and cooling over time. Just make sure do as Travis mentioned and re-torque the heads after heat cycles during the breaking period.  If you have o-ringed heads or block and true surfaces (near perfect), it's not required to use any form of sealer.

Nice. I haven't seen any of those parts on his website. Zach makes great parts too. Can't go wrong with engine parts from him or MWSC. 
10  Engine Help / Kohler Engines / Re: Kohler CH15S on: October 20, 2014, 04:02:44 PM
Zach manufactures parts for the Kohler singles now?
11  Engine Help / Kohler Engines / Re: Kohler CH15S on: October 20, 2014, 01:55:10 PM
The same type of performance parts that are available for Briggs or Tecumseh singles are also available for the Kohler singles. They don't cost any more to build than the other brands. Call and talk to Julian at Midwest Super Cub
12  Engine Help / Briggs OHV & Vanguard / Re: Valve Spring Part # on: October 19, 2014, 09:25:52 PM
I had some 38ci propane heads that had the purple stripe springs. I will get you a part numbers for those. The stock vanguard springs were around 14-15lbs and the were around 22-24lbs at stock install height, they can be shimmed for more. The big block vanguard springs would also be a good replacement if you have to use a stock Briggs spring. However, they are still not anywhere close to being as good as a quality aftermarket spring.

What exactly are your valve spring rules?

I talked to Ryan a few weeks ago and he plans to start doing some head work again when he gets his equipment setup.
