    Honda GX390 will not run.

    So.... I have the held all the way to the right if you are facing the engine at WOT. I loosen the jam nut and turn the governor shaft counterclockwise as far as it can go. Tighten jam nut back down. Start engine up and it revs to the moon. I can push the throttle shaft shut it will idle down but...

    Oh yeah swapped out the insulator and gasket it too before the carb swap .... no change. Thank you guys for all the help!!!! Don't know if I'm there yet but at least it runs somewhat now.

    Honda GX390 will not run.

    Ok here is a update- pulled the cover off double checked the cam timing which was good. Tried to start it a couple of times and it yanked the rope out if my hand. Swapped out flywheel and key. Original key might be bent... have to measure and see. Ran the valves again which were spot on. Still...

    Honda GX390 will not run.

    I did take the engine all the way down when I replaced the rings just to make sure there was no other damage. I really watched when I put the balance rod and the cam back in to line up the timing marks. ( Maybe I need to check again) Have not checked compression but I know it tries to blow my...

    I pulled the current tank off a running unit but let me try another one. I'm willing to try anything now. Thanks

    Honda GX390 will not run.

    So.... governor is adjusted correctly. Carb has good gas flow from the tank to the float bowl. And, I have tried 3 different carbs. Double and triple checked gaskets and insulator installation. Same result. It will only run on starter fluid. Beginning to wonder if I didn't get the head in...

    Honda GX390 will not run.

    I understand how all that works. That's the same test I do. As stated before I can keep it running with starter fluid all be it badly. I have plenty of fuel going to the carb. Tank is clean and a new fuel line. Tank is gravity fed and I can open the drain on the float bowl and fuel is running...

    Ool sensor wire is unhooked already. If the kill wire is shorting out wouldn't it keep the engine from firing at all? In the current condition I can restart it as soon as it dies. I will pull the wires tomorrow and see if I can find any bad spots. Thank you

    Honda GX390 will not run.

    Have a Honda GX 390 (GCBCT- QA2). Pulled it apart to put new piston rings in it. Got everything back together. When I went to start it it runs for a 5 seconds and dies. Will start right back up, but dies again. Will only start with the choke on. I don't even have time to turn the choke of...

    Cub Cadet BC490 4 cycle trimmer

    So a little update. Pulled the muffler off- no change still dies when start to open the choke. Unhooked the shaft (grasping at straws). Same result. Pulled the carb off and the insulator block to check the gasket to the head. At this point I noticed some oil in case under the crankcase hose...

    Cub Cadet BC490 4 cycle trimmer

    Gas trimmer will not run once you take off choke. Changed the fuel lines, fuel filter , carburetor, gaskets, plug and checked the exhaust. Fires up 1st pull on full choke, as soon as I move to the mid choke position it dies. Starting at wot like the manual says but even at full choke it only...

    B&S Fuel Tank

    Yea I had like six but have sold them all. Found a place in Texas that has 125 on hand but they won't sell to anybody but their customers in their distribution network. Lol Maybe someone will come up with a kit using a plastic tank and an updated carb ?‍♂️.
