honda roku check that your crankshaft mark is also aligned . Even if you checked upon installation you might have missed a tooth in the chain positioning if the chain had slack due to worn guides or sticky tensioner .

Hi there, some things I would look into before you tear into your engine any further would be:
1) When you did your compression test and found the compression low on the #2 cylinder, did you go back and squirt a bit of oil into the cylinder and recheck the compression? If the compression improves this is indicative of a ring/cylinder issue, not a cam issue.
2)Perform a leakdown test. On the #2 cylinder, if you have a poor leakdown the valves are suspect. The kits are like 30-40 bucks and are available at most autoparts stores, doesn't have to be fancy, you do need a compressor though.
3)You say you have a tough time rotating the engine, I would look at the timing chain tensioner. There have been improper installs that have had similar results and shortly there after failed the timing chain.
4) Check your valve adjustment. a mis-set valve will give you bad compression indication.
5)Testing for a bent valve, If you have a of bent valve the valve will have a shorter stroke than the rest, If you have access to a dial indicator you can measure the stroke of the 4 valves and compare, if one is shorter than the rest.... bad news.
6)If after all that you still have a bind, back off the bearing caps on the cams so the lobes not longer contact the rockers, remove the sparkplugs and try and rotate the engine, it should be smooth and free.
Hope this helps... Take Care.
