Faunsdale, AL | Take test light and ensure you have power to + terminal on coil. If no power, work back to switch.
If you have power at coil + terminal, then test on - terminal where wire to distributer connects. This should flash as you crank the engine over as the points close and ground the coil.
If power is found on coil distributer terminal, but no flash when cranking, test for voltage inside distributer on points/condenser connection. Wire could be broken, bad connection etc. if you have voltage there at the points, check they’re actually closing and gap them appropriately after filing the points. You may have some old stock points that came with pre-oxidized contacts!
If no power showing on distributer terminal of the coil, You may have an open coil, shorted wire on distributer, shorted points, bad condenser etc. take wire loose from coil and check for voltage again. If you get it that way, then remove wire at points and reattach the other end to coil. Test again inside distributer with condenser disconnected.
If you get flashing when cranking while testing distributer side of coil, then pull coil wire off distributer and hold near block to see if a spark will jump. If you have it there, reconnect and test for spark from a plug wire that’s held next to the block with a GOOD plastic handle screwdriver. stuck in it to hold it.
If it’ll spark there, check gap on plugs, try them grounded against the head and see if they’ll fire out in the air. Plugs could just be fouled. Don’t think you should gap them over about 0.020” but I’m used to propane so you might get better results with slightly wider gap with gasoline.
While plug is out put thumb over plug hole and crank to check it’s making compression.
I’ve found on my lp version that it helps to hold key switch to crank position even though I have an added push button to actually crank it with. The ignition switch sends a higher voltage to the coil during cranking, bypassing a resister on the back of the ignition switch. I usually wind up holding the switch over as the engine speeds up and levels out after i have released the starter button. LP engines can be a challenge to start!
I tried to put a gear reduction starter on mine but it was slightly too long to fit, so I had to go back to the original Delco. It would be nice to spin it over faster but I haven’t found a starter yet to do it. I’m getting along fine by holding the key switch over. I do run two batteries in it, that seems to help a lot.
