Here is some stuff about the LB.

1st. Check the magneto to see if you are getting fire. If you have it, then, the thing must fire at or just a hair past tdc. If you dont do it this way, when you try to wind it up, you are going to miss an arm.

2d. As you have had the head off, I think your problem is more than likely there.

When you view the front of the cylider looking towards the rear, at the bottom, there is a hole. In that hole there is a slip on square coupling. This coupling hooks to the govenor and carb. If you do not have this connected correctly, it will never run.

The butter fly valve in the carb must be full open while the engine is not running. To make this happen, take the rear access cover off. Get a light and shine up in there. You will see the governor shaft that runs to the front through the block. It will be spring loaded down. Get someone to hold the lever on the shaft with a screw driver in the full opposite direction. As they are holding this, you go to the head, and guide the butterfly shaft onto the linkage and install the head. When the screwdriver is released in the rear, this will allow the valve to go full open up front.

Bolt it up.

If you have proper timing, fire and gasoline, it should run.

If it does not, you might try a shot of ether in the intake. If it hits and runs for a moment, you will then know you have a dirty carb.

Check this out first. If you have further problems, get back with me. at twindsor@aol.com

PS. it took me a full 1/2 day to properly time one of these engines. The magneto should click just as the timing mark hits tdc.
