Horse fan 14 #1 Posted June 17, 2019 After around an hour my k181 has this feeling like it's locking up it spits and sputtered then quits. Sometime if I can get the pto shut off and the idle down it will stay running but if I idle it back up it starts doing it again......let it cool down and I'm good to go for another hour, valve problem? I changed the coil Share this post Link to post Share on other sites

If you have an automotive style coil and you put a coil on that does not have an internal resistor, you will get this type of issue.

Horse fan 14 #3 Posted June 17, 2019 I tried to fix it, the one I have in it now says on the side do not use external resistor....but I honestly believe if this isn't the right one the one that was in it had to be and it does exactly the same thing with both of them, thanks bud!

gwest_ca-(File Mod) 11,489 #9 Posted June 18, 2019 Not a big deal to check valve clearance. Valves expand with heat and if the tappet clearance is too small they can expand enough to prevent the valve from closing 100%. I don't think your valves are adjustable. They need to be removed and shortened to get the required clearance. If it comes to that clean the carbon off them as that will also reduce the clearance if it comes off after the repair.

Horse fan 14 #10 Posted June 18, 2019 Yeah I'm thinking it is a valve problem also and no they are not adjustable. I hope cleaning the carbon off will be enough cause I've never shortened them before, thank you much! Share this post Link to post Share on other sites

Someone with experience will comment. Garry Like Garry the valves aren’t adjustable. Check the clearance. If they aren’t in spec, pull the head and remove the valves. The valve stem base needs to be ground with a machine designed to remove the required amount of material and it needs to be square. I would recommend you take the block to a machine shop and have them resurface the valves, grind the valve seat and fit the valves properly. Depending on your area it shouldn’t cost much more then 50.00. buy a new head gasket. Don’t use the old one and torque in the proper sequence.
