Question about Karcher 2500 PSI Pressure Washer
I have an old Toro 421 with a 5HP Tecumseh HS40-55531 3F.
Engine wouldn't start at all when I got it.
I replaced the carb and it then it took off on the second pull.
I'm trying to tune it up and I'm looking for specs on things such as spark plug choice/gap, point gap setting, oil type/capacity.
Here's what I've been able to gather so far:
Any help would be appreciated:

You have a poor signal to the spark plug usually caused by a rusty fly wheel found underneath the pullcord casing. clean it with releasing ajent such as wd 40. common when not in use for a while.

here`s the go ,good possibility that you didn`t turn the gas tap off at the last time you used it.If the needle isn`t seating properly the gas wii over flowinto the carburetterif the inlet valve is open ,fuel can ,if the macine is on uneven ground run back into bthe cylinder and over a period seep into the sump. I`ve only seen it once .I am assuming it is a GX140 motor, so dont tilt it back too far or the same thing will happen with the oil and the mufler eventually gets full and it will sm oke like a forrest fire for a month. why do you say it takes longer to warm up ?is it because you have to have abit of choke for longer ?if so it is a mixture problem .and no it doesn`t need a new spark plug.

did you leave fuel in it from last year, if so remove all fuel from tank, drain carb. (remove float bowl if it doesn't have a drain bolt) put in fresh fuel, check your oil level and you should be good to go. if not, please take it to a qualified tech. for carb. cleaning.
