[SEL] Starting Stover - Need Help

[Curt]

Paul,
Have looked over the photos. I'm guessing you want to run this engine a 
bit slower than nameplate, as most of us do this for the show scene.
Is the spring you mentioned and pictured not for trimming the speed? Are 
there not a pair of (or single) other springs actually working on the 
flyweights in the cam gear?

I ALWAYS assure the latchout mechanism works FIRST before ever adding 
the first bit of fuel to an engine. You can block or hold the intake 
valve open to assure the engine freewheels. With the right springs 
working on the weights, you should be able to rotate the flywheels fast 
enough to observe the latchout engage. Then as you watch it freewheel, 
it will slow, and then the latchout will drop out, allowing the exhaust 
valve to close and follow the cam.

I assume you have checked the basics first, such as making sure the 
detent block will easily fit under the catch with about a 1/32 
clearance? And you've assured the cam follower and its' stud are in good 
condition? A worn cam follower, will diminish lift, and prevent the 
detent block from getting under the latch.

Hey, what are the small set screws on the sides of the main bearing caps 
for? Fore and after positioning of the caps? Did Stover engines come 
with these?
