Thanks for all the replies. Ground strap secured. I searched for Hobbs and finally ended up calling Honeywell as they are the maker of the Hobbs meters. Guy said they have discontinued all of their meters except the LM series. He also said that only meter that worked with 6 volts was a 85000 series, specifically 85331, problem is they are exorbitantly expensive. In the end I found a round hour meter on Amazon (Runleader HM009 DC 6V to 80V) for $13 bucks.
I had all the electrical hooked up and just for fun, I did a voltage drop across the negative lead to the solenoid to see if I had any drain on the battery. I was pulling about 2 volts drain on the battery. After disconnecting wires, I found that my ammeter (terminal type) was leaking to ground. So I ordered a new one along with the hour meter.
Got a bunch more projects coming: front mount distributor, governor, carb rebuild, then I will pretty much be able to start this old beast.
Might need some expert advise, thanks for responding.
