k181wont stay running

[857lover 291]

so i have my 857 and i really am not sure what to do anymore it seems to just keep dying and won’t stay running ever i replaced the coil,carb,cleaned the fuel tank, put a fuel filter on,new fuel pump and a new head gasket it will run every once in a while then die and i take the carb apart and “clean it” and then it works fine and i have no idea what’s happening i belive it’s a fueling issue it’s hard to describe in words but it seems like something you have to see with your own eyes but idk if you guys have any ideas

Do you have a good strong spark? Have you set the ignition points? What is the spec. number on the engine ID tag? If the suffix is  A, B or C you can check the timing with a timing light. If the suffix is D or higher you can use static timing to set the timing.

Your condenser looks as old as the tractor. Easy thing to replace. If it fixes it great. If not, at least its eliminated.

When it does die, safely pull the fuel line from the carb and see if it’ll pump fuel into a container when it’s cranking.  We need fuel, air and an ignition source.  Maybe before introducing fuel into the air, check to see if it’s sparking.  Either pull the plug and ground it to the head and check it while cranking, or use another plug to ground or better yet get an inline spark tester.

The main reason I like the clear blue fuel line. You can see if the fuel is flowing...

I'm with Squonk on this...  An old condensor will fail quickly once it gets warm.  It's a $5 item to replace and readily available.

I have to ask this. Where is the incoming fuel line from the gas tank to the fuel pump routed ?

if it is between the engine block and side bearing plate where the flywheel is get it out of there you could be vapor locking

i did consider this my k30 454 had that issue

Could be your fuel pump.I know you said you put a new one on but I would  disconnect and give a couple cranks and see if it’ pulses.

Theres some crappy aftermarket stuff  around rite out of the box .
