I have a Duro Max 16hp engine. Of course the pull start is easy to pull when the spark plug is out. When you put the plug in and try to start it there's a really hard spot that makes it impossible too start. Any ideas?
All of the suddenGive us a back story, has it gotten progressively harder to pull, or just all of the sudden?
I pulled the head off and didn't see anything wrong with the push rods or valvesAll of the sudden
No the plug is dry and I don't see any coming out when I pull the rope.Is the plug wet when you remove it?
Does any come out when you pull the rope quickly?
Exhaust .20 intake .15I am not familiar with the engine.
What are the recommended valve gaps?
Hope you mean .020 and .015?Exhaust .20 intake .15
