BMI has great quality parts and really good prices.  I've been buying chassis parts from them for years. They have great service and quick shipping as well.

I have several used Kohler heads, and a few new sets as well.

Ed is correct. Those are 426cc, or 26ci. The bigger CV490-493/ CV18 engines are 29.9ci.

I would use an electronic ignition setup like this one from Midwest Super Cub. It is for a Kohler, but could be easily adapted to a Vanguard.


5  For Sale / Mower Engines & Parts / Tillotson HR racing carbs on: September 26, 2014, 09:28:05 AM
I have a new matched pair of Tillotson HR racing carbs setup for gas, fully built and setup by George Herrin. I did some parts trading with George several months ago and got these, and they have been sitting in a box untouched since.  They are both HR-44 carbs, but are similar in size to an HR-191. They are race ready and come exactly as he sent them to me.  They would be a great pair for a Super Mod twin/ FXT engine, or individually on a Super Mod Single/ FXS.  $225 each shipped or $400 shipped for the matched pair.

I also have some matched 3/16" steel carb flanges I can include if you want to make your own custom steel intakes

Yes i usually keep a few intakes in stock. Send me a PM for more info.

I am working with a company right now to have billet steel camshafts made for the vanguard. It will be a billet core and lightweight adjustable billet gear. They are expected to be done by late November/early December.
8  For Sale / Want To Buy / Who Has It? / Re: Want to buy cam on: September 11, 2014, 01:10:13 PM
I would call Precision Cams and buy a new camshaft.  Finding a good used one may take a while, and installing a used cam can be a gamble considering you don't know the abuse it's been through. And i have some new starters here. Send me a pm.

You could save some money and just solder them up and drill them to the size you need.
10  Engine Help / Briggs OHV & Vanguard / Re: Parts for big block vanny 35hp on: September 03, 2014, 01:39:30 PM
Al Hodge at Performance V-twins has several nice parts for them.


11  Engine Help / Briggs OHV & Vanguard / Re: Could i tell a Cheetah with a dial gauge? on: August 31, 2014, 10:13:00 PM
As far as the camshaft gains, there are several other factors besides lift that make big HP and torque changes in an engine, including lobe center, lobe separation, and duration. Two cams with the same lift but different duration, lobe center, and lobe separation can have very different power bands and peak hp/torque. However, they could also be using the same legal camshaft but simply changing the cam timing.
12  Engine Help / Briggs OHV & Vanguard / Re: Vanguard timing on: August 31, 2014, 09:58:52 PM
The ideal timing for each engine can vary, depending on the compression ratio, rpm range you plan to run, and fuel you are using. High compression engines have a small window of timing.  Too much timing can cause pre-detonation and engine damage (ask the Briggs OHV single guys). On gas i usually run 31-34 degrees, depending on the blend of racing fuel and if it is oxygenated.  On methanol,  generally 35-38 degrees.
13  Engine Help / Briggs OHV & Vanguard / Re: Could i tell a Cheetah with a dial gauge? on: August 31, 2014, 04:10:57 PM
From what I read he has access to the rocker area so using an indicator to determine cam lift won't be an issue. The only problem I see is that the vanguard cheetah cam normally has around .308" to .310" lobe lift, and his cams have .304" lobe lift, which isn't much difference and might be hard to catch if he has a worn or cheap indicator that isn't very accurate. Especially if the cheetah cam has wear, or someone takes a few thousandths off the lobe lift to make it appear legal. 

Are these sealed spec engines, or are people allowed to build their own motors? If they are supposed to be sealed motors built to certain specs and cam timing, you could use the same method used to degree in racing camshafts. Use a degree wheel and check the cams for intake opening/closing to determine the intake lobe center and total duration. It would be a little more work, but it would be easy for me to spot a different camshaft this way.
14  For Sale / Misc. Racing Items / NEW Tiny Tach With Maximum Recall on: August 29, 2014, 11:07:22 AM
Back up for sale due to non payment. New in package Tiny Tach with maximum recall and hour meter. Great for adjusting rpm on governed machines, or even prepared classes when wanting to check max RPM after the race. Simple to install and easy to operate. $35 shipped to your door

15  For Sale / Want To Buy / Who Has It? / Re: Looking for a used Briggs 9HP Vanguard complete head. on: August 29, 2014, 10:34:40 AM
Those motors are actually an easy find and getting parts shouldnt be an issue. They are horizontal shaft ohv single cylinders used on a lot of commercial equipment and generators. I would check around on eBay. I have seen several parts listed for those motors there.
