My blaster quit on today need help

[Andrew wilson]

well there need help I was out on my blaster today on the track and after 8 laps it stopped and pulled it into the pit and tried to kick it and it wouldn't fire so I pulled the spark plug out and it was ok I think I might have something to do with compression can anyone help me figure out what's wrong with it

you can't tell if a plug is fouled by looking at it.
try a new plug, check for spark, check reed petals
do a compression test.
report findings

Shoot a very brief amount of fuel into back of carb see if it flair a and then dies, if so search out why it's not getting fuel
