My John deere b wont start replaced plugs and magneto parts including the cap what should be my next steps?
 
What year "B" is it would help. Hand start ? They need gas , air , compression and spark. Does it do ANYTHING ? We need help here. Usually a dead no start is bad condenser in mag , no fuel , or a broken mag impulse unit. If it is mag impulse, you can pull start it and will start fine then because it doesn't need impulse when pulled and engine turns over 250 rpm. To test for carb/ fuel problem....take air tube loose from front of carb and squirt some fuel in there while cranking. If it fires and/or runs for a moment , then you have a fuel delivery problem. Spark is self explanatory. You can always take mag off and have someone test it for you. You need good grade solid core wire plug wires for a mag tractor to be at it's best along with non-resistor plugs. Try a few things and give us some feedback.
