How long has the engine sat since the rebuild? I have seen many bent pushrods due to low mileage engines sitting without being run for awhile. Tight valves combined with old gas does this a lot. We ran into one recently that broke 2 pushrods and we pulled them out and I aired up the cylinder and pulled the valve spring to get to the valve and cleaned it with carb spray then worked wd40 into the guide until it moved free. We then ran the engine at idle for a bit using sea foam to loosen the varnish. We ran the engine gently for a bit and it cleaned up nice and ran great. Just make sure the old gas has been removed and put clean fuel back in. You already have it apart and I wondered what you found inside.
