When you try to start what does it do? Not turn over at all? Or turn over and not start?

It turns over it will start but run under 1000 Rpms while patting the gas then die then some times it will turn over but not start at all after it cools down to the first line on the temp Gauge it will start and sputter pat the gas and rev it then it's fine till the next time you turn it off but it starts every time if its cold I'm confused the guy I got it from said it was getting air in the fuel lines some how

I would check out your fuel pump ad rail. Could be staying open letting the fuel run out. Try turning your key robust before on to let the pump cycle some. See if that helps. It may or may not. You may need to replace some parts. Search a little bit more on it. There have been a lot of issues similar to yours. Sorry I don't know the specific answers

I'm gonna replace the fuel injector o rings and start up front then work my way back to the pump sometimes if ya let the fuel pump cycle about 22 times it will start but not always. Why would the engine bog though I can't go full throttle without it bogging out it's really anoyying while trying to play in the woods it'll bog trying to climb a hill even with it not full throttle could it be timing and thanks for the info

Not sure. If your valve in the fuel rail that's is supposed to keep gas up inside for the engine is bad that causes the start problem. And maybe it's not holding fuel when your Rpms are low due to same issue. Idk. I'm just going by what I have read.
