Drum on my concrete mixer is turning to fast

I recently took the diesel engine off my mixer and fitted a 8HP honda engine to it. Unfortunatly although the engine is in very good condition the gearing needs to be altered. What do i require and where can I get it from. Regards Bill Porter

At an engine lower and higher rpm is because of the governor sensitivity sistem.An arm attaches to the shaft(inside the crankcase)with a clamp-bolt/nut.This arm are provided with a series of holes.To decrease sensitivity hook the spring into a hole lower than its original position.If needed you can make some extra adjustment holes.Hope this help you.

Looking at a bed edger and the compression is 90 psi is this something that i should worry about.

The Honda 8HP motor will work OK with 90 psi compression but it's on the lower end of good. Most likely it will need new piston rings and possibly the cylinder resurfaced in the near future. Low compression could also be caused by valves not seating completely either from wear or carbon buildup. Depending on what you are looking to spend it may be worth your while to remove or have removed the head to inspect the valves and cylinder wall.

I have a honda 8hp on a mortar mixer. it gets fule in the bowl but will not run long. lite iys just using the fuel in the bowl. It used to run great. It has sat for a year.

first thing to do is take the fuel bowl off.then turn the fuel tap on.fuel should be running out of the needle from the carby.if not, the needle and float is not working properly. turn the fuel tap off .spray some carby cleaner into the needle and seat. turn the fuel tap back on and lift the float up,this should stop the fuel from coming out.and when you let go of the float,fuel should start coming out.
lift the float up and down a couple of times to ensure it is working. put fuel bowl on and run.

Honda 8HP GX240 willnot start after working fine.

Your carberator has crud, or rust, or glaze in it. The carberator will have to be removed, soaked in cleaner for three hours and then rebuilt using the proper carberator kit from any auto parts store. If you need to hire this done expect to pay about 35 dollars.
