Did you end up getting the engine to start?

Heymow has always been a great site, I'm going to try to get on here a little more often.

What magnet are you running?

I ran the same set up with a short stroke crank, it worked very well with a killer set of heads and two carbs at 12,000 rpm. If you are running an intake manifold without a killer set of heads its not likely you are reaching rpm like that, so you would benefit from the extra cubic inch. You can still run a longer rod with 23hp crank.

I'm still doing heads. ;)

For the ultimate seal on a vanguard, I o-ring the heads and use my own design of copper head gaskets available in every bore size from 30ci up to 38ci including big custom sizes.

The 30ci block castings are really light around the cylinders compared to the 35-38ci blocks, I wouldn't recommend using them if you are looking for bigger cubic inch.

Its a 1994 16hp engine and it should have aluminum rocker arms as well.

I can send something out, just so you don't feel out of the loop :lol:  by the way Rooster I'm going to need some banking information and your current address and so on  :lol:   just kidding
My cell phone went nuts with messages from a lot of people too, they all came at the same time.

Thanks guys.

If you received an email from me that was bogus, somebody has hacked my account and everything not only on heymow but everything that involves a computer. Please disregard all messages that are not purely business from me. I'm doing everything I can to get the problem solved.

Briggs OHV & Vanguard / Re: Rocker Ratio
« on: February 14, 2013, 04:04:04 pm »
Sure, they are probably all very close but you can choose the best push rods to get what you need. You will have to put a dial indicator on there and see what is the best, then try to find more like it. On the vanny you can probably tune the length by drilling the push rod seat in deeper on the lifter if need be, or the rocker boss height on the head can be slightly milled down. You will have to do some playing. Also the length of the tip of the valves above the keepers can be altered to give you what you need as well.
On the vanny's when you get milling the heads and changing the base circles on the cams it gets everything out of wack. I used to have longer stem valves and raise the springs and use different pushrods to correct everything on my engines, it was worth the effort and noticable on the top end. Not to mention that it cut down on a lot of wear. I had to weld two valve covers together and make a taller valve cover.

As mentioned, the rocker arm ratio in itself is what it is, that can not be changed. But the total valve lift can be affected buy the pushrod length . It depends where the rocker arm travels in the arc, that will change the rocker lift ratio. The idea was right, but maybe not the best choice of words.
An example would be: two identical engines with 1.6:1 rocker ratios. One has an optimal pushrod length with perfect geometry acheiving maximum valve lift. The other engine has too long of a push rod making the rocker spend more time at the bottom of the arc going sideways on the valve tip(in a lower arc) rather then up and down in the arc like the other engine.

There is only one crank besides the different strokes available.  There are several different bolt on counter weights for each rod and piston combination even before its balanced. Its a pretty big range from 38-56ci.

I've bent 5/8" shank joints just by catching a wet bale, I wouldn't run anything smaller then that myself. You can get 5/8" shank joints with 1/2" eye's. A few grams of extra weight isn't going to hurt anyone if it means finishing a race or not.

If that didn't do it, the billet cranks from MWSC and steel cranks are one in the same in this case. They are billet steel cranks. They can get pretty heavy but that is based on the cubic inch, the heavier the rods and pistons the heavier the counterweights need to be. The stock cranks are cast iron, however if you read the kohler literature it says that the command pro engines have steel cranks. I believe they are the same cast crank with a hardened rod journal for extended life. But that really doesn't matter much when you break the pto off of it.
