Unhook the ground wire coming from the switch to the points, maybe its grounded all the time. There is literally one wire needed to run the engine and that is the little wire that goes from the mag/coil to the points, I think its a black solid core wire. Set up the coil gap using a business card or a matchbook cover. I don't remember the point gap, but .020" should make it run. Try a different spark plug.

Check to make sure the points open and close. They must make contact and break the connection. The spark occurs when the break occurs. Sometimes measuring the point gap is a mistake if the plunger that opens them is worn. Have you substituted a known good condenser?
thanks a lot guys readin these post pretty much keep me from selling the thing i dont want to do it i doubt i will but ive had it cross my mind im gonna adjust the points tomarrow i dont think mine touch and then open i think there always open and then just open more.

I've always found that when I get to that degree of frustration with some machine, it's best to walk away for a day or so and try not to think about it.
It's amazing what your sub-conscious will figure out for you sometimes, or if nothing else you come back with a clear mind and start over.
I would hate to see you give up because it feels so good when you do finally figure it out.

My 990 with an engine code of 326431 0139-01, was not running this spring and I bought a new coil for mine that does not require the use of the breaker box.
There is only one wire that connects to a ground, and my old engine fired right up with it.
I am at work so I will post the part number when I get home, but maybe someone here knows the part number off of the top of their head.
I did not have to have the flywheel re-polarized, just followed the instructions included with the coil and it ran like a champ.
I hope this helps.

I haven't tried this with my 990 (i know others have) but i was having the same issue with my David Bradley until i spent $20 on one of the Mega Fire modules and one of those E plugs (i know i have one in the 990 that is an E10) and now I'm getting tons of visible spark on the Bradley, no fire yet except for back fires from time to time so i know your frustration. Other bad thing about the Bradley is it's a non recoil pull so I am exhausted and ticked after trying to get the thing to start for half an hour. I have tried every trick in the book and I'm so close yet so far so i decided to take a step back from that project for a bit before i decide to dump it. Don't give up, just take a break from it :trink39:

Yeah,dont give up and sell it,much as you may be tempted too--I have given up a few times in frustration,and GIVEN a tractor away,I was so aggravated with it--then see the guy I gave it too USING it the very next day,after finding some STUPID thing I overlooked that was keeping it from running!..too add insult to injury,he SOLD it to someone for 250 bucks about a week later!..glad I got it free,or I'd really have been BS!..
I also find the more frustrated you get at something,the less likely you'll figure out the problem--and be MORE likely to take a sledge hammer to it!..best to walk away,as suggested..
One thing you may have overlooked,when you bolted the coil on,did you make sure the right side is facing the flywheel??..been there,done that!..I think the plug wire should be facing the flywheel..
