be sure to hook the 2 batteries from + to -on each 12 v battery to get the 24 v then try it

yes i have two bats to get 24v and sol clicks but no starter.. letting the batts charge up a while to see if its just a low voltage issue.

Do some of the 24v starters as late as 83 use positive ground?

should not be positive.

what was the BAtt voltage when you tried this? 

you can have a battery that shows good voltage but does not have the load capacity to crank

No you will use up the starter remove the filters and fill with fuel or remove the plug on the primary filter and pump fuel through it either with a electric pump,squeeze bottle or garden sprayer

Not unless you want to replace the starter again.  Try filling the fuel filters and then try it.  If you cranked it after it stopped you will probably have to put some pressure to the system.  I recommend an inline fuel pump.  Makes priming a snap when/if you run out and makes changing filters a snap.

good luck

It may take more than 1 time filling the filters fwiw

leave it inline all the time or just to prime?

What pump do you recomend?

Don Fairchild NEVER uses a primer pump-he says it is to easy to blow the pump seals. I watched him prime my engine. He took off the fuel lines one at a time and filled them with fuel. Then filled the filters with fuel also. Then cranked. He repeated this process 3 times and on the fourth try it started. Don said that is typical. Good Luck, TomC

I bought a Facet-Purolator pump for this purpose, but I made sure to get one for carburetted cars, not for cars with fuel injection.   The difference is the pump's output pressure  -  mine is only 1 or 2 PSI, but EFI pumps are a lot more (40-ish?).   I've used it once when I got air into my Racor 900FG's fuel bowl, and after running the pump for a few minutes the engine started right up.   Easy!

Takes a lot pressure to blow a seal in one of the old DD fuel pumps they are double sealed took over 100# of air when I did a little test, 20# is not going to blow a 70#psi seal 

I guess Donald blew one of the old types years ago he doesn't forget somethings lol

The pump up garden sprayer had the right thread to the port on filter 2 and it worked perfect!

Thank you!!

Runs great!
