Default Trouble starting John Deere 1 1/2 hp engine

Like title says trouble starting 1 1/2 John Deere hit miss engine Have checked the fuel screen, fuel line, and check valve and all are good I made sure the mark in carb needle was horizontal also I have brand new mag but am try with battery and coil mostly Everything is time perfect on spark and exhaust open etc The rings appear to be very good The cylinder had few light spots but nothing that looked to serious We honed it out anyways Bearings are all good and replaced spring on ignitor Btw it's a 1944 model if that helps any but think they are all same except older ones didn't have breather Anyways all that and still won't run Tried with carb 3/4 to 1 open and choke closed but best results have been 1/4 to 3/8 on carb valve and choke slightly cracked Feels like it'll try to take off but still won't run Not sure on governor but think it's screwed in bout half way it'll go Any more ideas? Not sure what to try next Btw replaced intake valve Exhaust seals good but new one on the way anyways in next day or so

Is the gas getting into the neck of carb? I noticed you replaced the intake valve, by chance is the spring to stiff not letting the valve open?Also it could be out of time too, but if everything on the outside lines up it should still run off a battery and coil,WITH the Mag unhooked from the ingnitor,make sure the ingnitor is snapping the anvil right and is moving a little,just some stuff that have run into before........ I posted a thing in a thread from a JD manual how to time a mag, the button or rivet marked L on the mag houseing should drop into a slot and then JUST start out, just as the ingnitor trips when the flywheels are turned slowly the direction it runs,sometimes these if after being rebuilt need to be belted to another engine to make them a little looser to run untill the rings get broke in..........

Your battery is probably crapping out on you. The JD ignitor is normally closed, only opening and then snapping the points at time of fire. That means your battery is shorted out 95% of the time. So it will quickly tap out a battery unless your running a car battery which would proably melt your wires and points.

It is desired to have a low tension rotory mag operate into a short (points closed) as opposed to an open. In general, this is to prevent inductive flyback energy generated with open loads from arcing over to random places and destroying wire insulation on a generator.

There are posts around here that describe how to convert a JD ignitor to normally open to run battery and coil. But I'd just run it how it is, on the mag.

Yes using car battery with low tension coil only leave it connected for short time while trying to start Also I have battery hooked to charger every so often to keep charged And I am concerned about how much air/fuel the intake is taking in Replaced intake valve but same spring on it as before Lots of fuel getting to mixer bowl but doesn't seem like much getting to ignitor to me I've heard about putting fuel in ignitor to try to start but unsure how much to try Also does anyone know the best spot to set governor at? How much stem should be out past nut? Thanks for helping everyone

Is the mica on the ignitor good? If the stationary electrode wasnt insulated couldnt the current just short out through the ignitor body and never cause a spark?

You could test it by hooking up an ohm meter turning the movable electrode backwards causing the contact to break. If there is continuity through the ignitor when the contacts are not closed then that would prevent a spark I think.

Goomba and Gilbert are right on this ,another way to see if you have a mica problem is to move the points open on ingnitor and see if you have any sparks when you touch the wire to the movable point contact, where the mag wire goes,if so you found your problem,on some if there is wear you can close the points while it is in the engine and move them back and forth to clean the crud off, if this not the problem also.One more thing might be happening to is if you have flooded it,the alcohol in todays gas Will short it out,just like a spark plug...........

Thats good!!!! Now when you get another engine you can start ALL over again,trying to find out where they like to run, LOL, Seems every engine is different,think about working on a Gade 3hp air cooled, that if you get to much gas in it, you take off the muffler and crank,it draws air through the muffler on a port and the exhaust valve! If gas or oil gets in the muffler it draws it back in the cyl and now you have a VERY rich mixture,or if you forget to turn the oiler off you have a oily mess when she fires after, you crank and your arm feels like it about to fall off,then have to remember how the Stickney likes stuff too, these are very different,Now you will have to remember what all of them like!! ROFLOL Welcome to the addiction!!!!!

disconnect the mag from the igniter, connect a voltmeter to the mag. spin the engine, should show about 7 volts AC or so. If not, clean the brush, maybe replace it. Don't take the mag apart unless you are prepared to recharge the magnet.

Keep in mind, Lightning Magneto should have any parts you may need as you dive into the project.

How do you check the mark for being horizontal on the valve needle?

Look on the nut that the mixer adjustment needle goes into, it is a line on the nut, there is 2 holes in the part that goes into the air stream and aligns them where it should be, just opposite of what you think it should be to!! The air goes around those holes instead of through the holes and draws the gasoline in the air flow that goes around the holes, kind of like a air flow a airplane wing creates ..
