Setting the valves on a TO- 30

I am in the process of fixing a leaking valve cover on my TO-30 and thought I would set the valves while everything was off. I was wondering if anyone her has ever tried setting the valves with the engine running at low idle. I have done some engine work before and have always set the valves with the engine off and turning it over by hand.Both the service and owners manuel give the engine running method and it must work, but it sure looks like trying to hit a moving target to me. If I set the valves without running the engine, is there a better method of turning it over to open and close the valves than using the starter as the manuel suggests. Any input is appreciated. Thanks, Mike

If you have another old valve cover, you can cut the top of it off exposing the valves for adjustment but the side walls will keep the oil splash to a minimum.

Turkey...
you have gotten some good advise from the other guys. My 2cents - adjust your valves tappets cold first(room temp), engine off, turn your engine with the starter or a big wrench on the crankshaft pulley nut. That will get your clearances very close, or right-on. cold is .013", hot is .015".

Then check hot, engine running, slow idle like the other guys said. If you did a good job with the cold setting, you should be able to just check, you probably won't have to actually adjust more than a couple valves. If you feel more comfortable, shut-off the engine, adjust, re-start engine and check after the valve has cycled a few times.

I have always set my valve hot and running on my TO-30. The trick is to get the ide as low as possible to minimize the oil splash. I use a plastic soda bottle filled with gas and a piece of tubing stuck in it, the other end of which is connected to the end of the fuel line to be able to run the engine with the tank off.

Most would set them with the engine running then you can hear if the tappet is slack or worn. You can turn it over with the starting handle. If you take the plugs out you can turn it over with the fan belt too. With the engine set correctly it will idle at 400-450rpm.

I have been a mechanic for over 40 years and most of the equipment I have worked on was adjusted while running. It is not hard at all once you get the feel of it. I think it is a lot more accurate than rolling it over by hand.

Just goes to show how peoples preferences differ. Since 1964 I"ve worked on marine, industrial, commercial, in fact everything from race cars to lawnmowers and I"ve never adjusted an engine running yet. Tried it a couple of times - mangled the feeler gauge in the process.
Frankly I can"t see the advantage unless you"ve got a cam follower so worn that it"s high in some places and not others.

I'm like gerard, I set valve cold too. I set intake at .015", exhaust at .018". When the engine gets to operating temperature the settings are quite near to the hot settings of .013"/.015". Valves set too tight will cause hard starting, and valve/seat erosion.
