[bkwhite98]

I Just got it out of storage put in fresh gas and it fired right up but after I let it warm up put it in gear and take off at about half trottle it trys to go dead everytime. Any suggestions???

if its been sitting for a while change the spark plug and oil and cleen the carb n lub everything that can be lubed n it should run like normal again

its prob your carb dude take it off and make sure your jets arent clogged and there isnt any varnish in the float bowl

ya id say change oil take off your carb and check for all the regulars like clogged jets, varnish and what not
