Hey guys ,
I recently purchased a 96 Fourtrax 300 in rough shape and not running.
The carb body was busted from hitting something when the previous owner rolled the quad over.
I replaced the carb with a new caltric , installed factory specced jets , set pilot jet at 2 1/4 turns out. Then I removed the gas tank and cleaned it out well , removed the petcock , cleaned the screen , and flushed the tank with fresh gas .
The existing battery was trashed so I replaced it and rebuilt the starter because it wouldnt turn over.
I then changed the oil , oil filter , and air filter before trying to fire her up………and no go. The spark is white and intermittent so I order a new coil. Replaced the coil this morning and have the same symptoms. The motor turns over well , spark plug is wet with gas but the spark is still weak and random.
When I hit the start button it might spark right away or it might be two seconds before it sparks . I dont have a compression tester but the compression blows my finger out of the plus hole with authority.
Any ideas?

By the way , I do have the manual and plan on testing the resistance and voltage in the other ignition components but wanted to see if anyone might have some insight.
