Car: smartech offraod buggy 2

Hey ive been into cars for about a year or so now and i cant figure out this prolbem w/ one of my cars. When i started driving it all the sudden the gas cuts really low and eventaully shuts off when i pull the throttle on high...it can idle but when i gas it, it cuts out...

second thing is this..its very very difficult to start. i cant get the gas from the tank to the needle....I'll push the button on my gas tank that forces it to the engine, but it just comes back. I dont know what the hell is wrong with it.

You most likely have a air leak...check all the tubing and seals...you should try taking out the tank cleanin it out then filling it up with water..then try to prime it by capping the exhost part and see if any water runs out of the tube..if that dosnt work check the seals..if thats not it..then you may need to check the piston and sleve of the engine..your tuning may be off as well i would first try to tune it set it back to factory setting (should say in the manual for the engine) *normally like 3 turns from resistance* then you should re-tune it...if all of that dosnt work you may have a dead engine on your hands and need to invest in a new one
