Chris,
I have used a Atom computer ignition module that I picked up at my Carquest. It seems to make a differance in how they start. That does not mean that your coil may not be weak but this unit should help and it is cheaper than points and condenser.
Speedex tractors are great fun and easy on repairs, Have fun!!!!!!!

Ron,thanks I have found that online and a couple others am gonna try one but the coil is brand new and is O.E.M from Briggs is it still possible its weak?Also have read about having to repolarize flywheel?I would think I would have weak spark all the time in that case.I don't know I'm new to the speedex and these older motors.Heck the tractor and motor are both older than me but with a little help I will figure it out.Thanks again

Have you cleaned the rust from the magnet on the flywheel?or Try a new plug,or both.That should help.

My 1030 w/a 15HP Briggs had the same problem- Rather than tear into the engine I used an old 12v automotive coil- Run a line from the Battery + to the + side of the coil then run the - side on the coil to the points to pulse the - side to ground. Connect the coil to the spark plug and your good to go till you feel like tearing into the engine. PS-Good idea to make sure the + has a fuse in line (20 amp)
