petcock on, ignition switch to on. when i i start it engages the starter but wont turn over. i can hear it almost combust. put new plugs in. battery fully charged. shall i spray ether in carb?
Don't over think it..
... get a good / full charge on the battery... shoot a little starter fluid (or any fuel you wish) into the carbs.. choke it..you say you have spark.. and I'm pretty sure you have "Air"...
go from there...
I remember at sometime I either heard or read "90 percent of your electrical problems are carberator related"...
