OK so i was going for a ride today and when i started my wheeler up in the back to take it out front to put gas in it. i shut if off then it was running after i did it and i gave it some gas and it died. after a while i got it going around the block and it was spitting terribly. every time i brapped on it it got to an rpm and spit... i got back home from around the block and shut it off cause on the back stretch it ran good. i got it to 5th gear good so i thought it was good then all of a sudden it starts like spraying oil out ontop of the head gasket and everywhere there is a seal oil is comming from it. when i changed the oil i gave it a whole quart but it was supposed to take 1.8 or something and it spewed at just about 1.0 so i got as much oil as i could out... i went on a ride last week and everything was perfect...any idea why it is doing this now?? ok i got it to run by draining some oil but it still isnt running right. it has no tourqe. every time i would brap on it it was like act like it has no gas... WTF! like it keeps starting and running then i brap on it and it dies, or i have to rev it hard to keep it going, and sometimes when im stopped and slowly let the clutch out it stalls, and yes i know how to run a clutch very well... so its not that...maybe i have some bad gas? should i put some of that like dry gas or somethin in?

ok ill try that! my dad also said that i may have blown a head gasket and now its running lean so when im trying to get that power out of it it is sucking air into the pistins or something... could that be a possibilty or no? seeing i have already run it o and i forgot to add this. it has stage 2 hot cams and the guy i bought it from said i should run 93 octance with a 103 octane boost. and i didnt know this but the gas i had in a gas can at the house was 89... haha and no octane boost. now with this said would it be leaning more toward the gas part or gasket replacement?
