My prowler has had a valve sticking? One cylinder will not work. Max speed like 35 mph. Anyone know how to fix it? Thanks

Mine was a bad spark plug, idled smooth but couldn't get out of it's own way.

Carbon build up keeping the valve open? I'd go with diesel racers advice first. Replace the plugs, check the spark plug boot for wear. Last option of a hung valve is to pull the head.

I took the plug out doesn't look bad but going to replace them. I'm gonna squirt some on blaster or something in there let it soak out the plug back in hope it fixed it... I don't really know how to pull the head...

Great news replaced plugs and let some spray lube soak in the cylinder. Started right up! Must have been a bad plug. Thanks guys
