Is it all electric? If so, that is maximum load (pump, blower and ignition spark) . Is the breaker on the machine or in your house/building? If yu have a 20 amp machine plugged into a 15 amp circuit it might run cold but trip out when you add the spark and burner blower. Also check if there are other items using the same circuit. If your extension cord is long and light guage wire ( smaller wires have larger numbers, 10 guage wire is heavy duty and 16 guage extension cord is light duty) it could be the cause of the breaker tripping.
What brand of burner are you running? I am a Karcher Tech but they all work on the same principle,
Your burner is getting to much diesel/kero, most have little flow swicthes on them to tell them to pump fuel or spark when there is water present in the burner coil, if this switch is faulty or getting a faulse reading then it will tell the unit to pump fuel when it is not needed and this will cause very excessive smoke for the first few mins when the burner kicks in...
If you have the excessive smoke continuously(even after 10 mins of continous use then it is probable that your fuel pump/system is running to rich, these units need regular servicing and adjustments as fuel nozzles/components wear,
There is alot of precise adjustments and checks on these units and i would reccommend getting it checked by a qualified tech, as when there is heated fuel and spark these units can be dangerous!
Most Honda engines have an oil pressure switch that prevents engine damage due to low/no oil pressure. Make sure there is sufficient oil in the engine and that the wire is connected to the pressure switch.
Sounds like the regulator is sticking or is airbound. loosen the water connection and then tighten it back. Could also be that the trigger gun is faulty or needs adjustment. Hope this helped
you need to replace the fuel pressure regualtor underneath the plenum , ck fuel pressure if it drops suddenly after you shut the engine down suspect fuel regualtor , use to have to replace the whole spider assembly now i think you can just replace the regulator
