It will die if you give it gas...and actually, if you give it just a little, it will chug real bad until you let off. If you give it too much...well...it dies. When I first start it and have the RPM at around 2 grand, it kind of putt, putt, putt's until you let off. Then it is up to the motor what happens next - sometimes it then dies, and sometimes it will run ok (for a little while...until it dies). But on about the 5th start, it will do the putt, putt (when on the gas) kinda thing and then run fine. I will sometimes give it a little gas (which then the putt, putt thing happens) and then I will give it half throttle; putt's for a little while and then the rpm's shoot up and it runs fine (this is of course on about the 4th or 5th start). but after I have run it for a while (driving through town or something) the next start works just fine; it only happens when it has been sitting for a while (over 4 hours).
