interesting..... i squirt fuel in carb right after i check the oil on all non starters for pops but the only firing pops i heard on this one r like backfires in the exhaust as if the cam tiring is way off or the exhaust valve is sticking open.....i removed the rocker arms and both valves bounce...
have a new mower with a 675exi....very little use never ran low on oil yet compression is low and now doesnt start,,,only 10 psi on compression guage, spark and fuel r good, valves r closing NOT sticking open cause rocker arms valve lash in spec.help!
