Before I replace my coil

Unfortunately, theres been a rash of recent rebuilds affected with incorrect camshaft gear index marking. Its rather obvious if'n yer looking fer it.

If'n your compression is low like I suspect, yer gonnna haffta take both the cylinder head and the timing gear cover off and visually inspect the position of the #1 valves both closed and the #1 piston TDC.

You'll have to manually crank the camshaft around so that BOTH #1 valves are closed (cross-check both #4 valve open) You can tell by feeling the action of the valves with your fingers. REMOVE the camshaft gear.

Now manually crank yer crankshaft until #1 cylinder is TDC with the index next to where the camgear (thats not installed right now) should be. NOW INSTALL the miss-indexed camshaft gear without moving anything. NOTE: the indexes will not match up if'n yer doin it right like I tell you.

Now then, once ya gotts everything TDC'd, valves seated, piston TDC, drill a new index mark on the camshaft gear soes the next poor mechanic has a fightin' chance.

As I say, the camshaft/crankshaft miss-timing is rather OBVIOUS if'n yer lookin' fer it..... ...Dell

Glad to here your ok. I heard of an Ole who was shot up near the Canandian border. Seemed he had taken his N right up near the border and was cutting down some trees for fire wood. The Border Patrol came over a rise near him and when they saw him they shouted,"What's your name, and what are you doing up here?"

"Ole...been loggin"

Bang!

Okay - I know I have a warped sense of humor..

Good Luck, Jim

Measure across the Ballast Resister (one probe on each Side)

With The Point Open = 0.0000v (this is very important and means the circuit is open)

With Points Closed = ~ 3.5 but not lower than 3.0v (in your Case)

K-Law: VD of Ballast + Coil + Other = Applied Voltage ( 3.5 + 2.7 +.4 = 6.5V

If that is all correct than you have the right amount of current in primary of coil and your
problem is in the secondary (HI Voltage)

Replace Condenser. This slows down(prevents arcing) and the rise time of hi voltage, it also is responsible for 3rd & 5th harmonic energy.

Hope This Helps,

2.5 volts at the coil with the points closed is too low. You should have about 3.5 volts with the points closed. I would look at the wires and electrical connections from the battery to the coil. You need "clean, bright, and tight" (quote from Dell) connections. Wires to check are:

1. From starter to ampmeter.
2. From ampmeter to terminal block.
3. From terminal block to switch.
4. Bypass switch.
5. Switch to ballast resistor.
6. Ballast resistor to coil.

If you still have original wires, you may want to consider rewiring it.

ideally, 3.2 volts at coil with points closed, but my 2N starts well with only 2.6

check the plugs - are they wet? she may be flooding. Try starting it with the fuel shut off - it should run for about a minute with what is in he line and carb.

also try taking the cup off of the air cleaner - maybe you are restricting too much air with the colder temps in the air these days.

coils go bad more often than not - I keep a spare laying around, but you said that you have sparks - if they are bright and blue, then your coil is good enough to start it up.
