I have a strong battery but hard to crank engine. If it wasn?t for an easy to start engine, it would never start. I have been having fuel issues so I once again pulled the carbs, cleaned them up, replaced a cracked cold start solenoid cap and put things back together. Primed things up and gave it a try. As always, very sluggish cranking power. Made several attempts but now it wont even turn over. When I hit the ignition, all I get is one strong click from the solenoid. I pulled the cables and cleaned/polished. No success. I suspect either the starter or perhaps not getting enough current to the starter from the solenoid but what do I know? Is there any easy backyard mechanic 'want to be' testing that can be done before I just start buying parts? any suggetions would be greatly appreciated.
