How to adjust valves on Briggs Stratton model # 310707, type # 0136-E1 Engine turns so hard it can not turn over.Battery & starter are OK.

sounds like you have good compression. It should be hard to go up to TDC... again valve adjustment would not affecf that much if any nor would it affect the ability to turn over. If there is too much carbon buildup in the head, that would increase the compression and make it hard to turn over. Normally you would not get such buildup unless you were running real rich mixture or the choke were stuck part way. If valves were STICKING and hitting the piston then that would be a problem, but that is NOT an adjustment issue. Searching I found this site: http://www.askmehelpdesk.com/advice/t-31... They state that intake is 3 to 5 mils and the exhaust is 5 to 7 mils. One site said the lash is critical for a compression release. Worth checking these though. sounds like you have good compression.

uh, YEAH, Fred, it DOES affect turning over...well known issue with OHV engines...try it and see!! uh, YEAH, Fred, it DOES affect turning over...well known issue with OHV engines...try it and see!!
