Rebuilding a 08 teryx for a friend. it was ran out of oil and rod bearings failed. engine was fully rebuilt. a new crank, pistons, rods, rings, and all bearings were used in rebuild. engine has great compression, bright blue spark, getting fuel, valves are in spec. will not start....the cams are in the correct spot, and timing is right on the money. battery is pretty dead so i have been using a jumper battery from a spare vehicle. rolls over decently just wont pop and fire up. wont fire on a squirt of starting fluid in the carbs either. any advice is gladly welcomed!!!!
