Hello, I recently acquired a 2005 Rancher 350es that has been sitting for a few years and it wouldn't start. I've done so much to it. Changed engine oil and filter, air filter, rear diff oil, choke cable, spark plug, gas valve, gas line, jets in the carburetor and cleaned the carburetor and gas tank out. It will start now but won't stay at idle and die. Also as I'm driving it runs for awhile then dies. After it dies I can get it to start and it has to sit for a little. After sitting for about 35 minutes it will start. I have no idea what could be wrong and causing it.

You still have fuel supply and carburetor issues. First thing you should do is verify fuel flow from the tank to the carb. Shut the petcock off, pull the fuel line off from the carb and hold the end of that line over a container. Turn the petcock on and watch for free flowing fuel coming out of the line. If it flows out slowly (or flows good for a bit then slows down) either the tank vent is clogged or the petcock strainer in the tank is plugged up.

Now your carb... you'll have to completely disassemble and clean your original OEM carb again. You'll probably need to put all of the original jets back in the carb as well, because odds are those new jets you got aren't OEM... but china knockoffs?

There are two ways to do this... you can use Berrymans carb solvent and soak all of the metal parts for a day or two, OR you can slow-boil all of the metal parts in Lemon juice until everything is clean and bright. Patience is required for either method... and you must be very thorough or you'll be doing it all over again.

When all your original OEM carb parts are clean, blow compressed air through every passage to clear them. Then reassemble the carb step-by-step as the factory service manual recommends. After the carb is set up perfectly install it exactly as the manual says. Adjust the cables as well and clean the air filter.

Do your best work, skip nothing, you'll be riding it very soon... keep a smile on. ;-)

Thank you very much for the information. I will have to try that. I replaced the fuel line and the fuel peacock selector with fuel filter and it's flowing gas but I'll have to check the tank vent to see if it's clear. The carburetor will have to be cleaned again and more through. I appreciate it and can't wait to get it running normal.
