I have a small,old Mitsubishi engine driving a Modra generator. It's a good unit,but the top of the carby has a crack in it & fuel leaks badly.Carb has number 621 024 on it.
Anyone know where I can get a new/used carby ? Or could I make do with another carby?If so,how do I assess what carb to buy.(size,etc) --------------------------- Also,I have a Kawasaki 2300 genset.Today it started blowing fuses.It has 2 fuses..15 & 10A.The 10A keeps blowing. It starts Ok,but acts up when I plug in the lead... What do I need to look at? Was running well before. Luckily,I have a spare 2600 for parts.Very similar looking,but this unit has a trip switch,not fuses.
Thanks for your advice.I always get good info here..
If you cannot find a carby, you could try cleaning and widening the crack with a scriber or such and using epoxy weld to fill it. As to the fuses blowing, you say it happens when you plug the lead in, but do you mean when a load is applied or just the act of plugging in the lead? If the latter, have you done or had someone do a resistance check on the lead in case it has an internal short?
With regard to the carburetor, I can't make a suggestion beyond the traditional vintage car repair one of adapting another carburetor to suit.
Concerning the fuse-blowing, does the fuse blow with nothing plugged into the outlet? If the answer is no, it sounds as if you need to look first at the thing you are plugging in, not the generator.
Hi AusTrev & Grumpy, I'm thinking of finding another carby,as the crack is long & covers humps,bumps & corners.What are my main considerations when looking for a replacement.The engine runs well,but parts on a 30 year old Mitsy engine are hard to find. ------------------------------ I was using an old drill on the Kawasaki genset.It had been going well,but it died,but not sure if Genset killed it,or it just died & hurt the genset. The revs seemed to alter a little when I put the lead in (no load). I'm wondering if the 220V power rating is an issue? This looks to be a USA style plug & I use a short adapter lead to plug in to. The genset & drill had just helped me build a small shed ,so had worked OK all week. I guess I need to know what to start testing.I'm pretty sure the fuse blows after start up. It would be easy to go buy a new genset,but these old things are built better,so I'll try to keep them going. Thanks, Jim
Usually the main considerations when choosing a substitute carburetor are: 1. It fits in the available space. 2. Its mounting flange is easily adaptable to fit the cylinder head. 3. It isn't difficult to couple it to the governor/speed control. 4. It is easy to arrange a reliable air cleaner for it, that will fit into the space. 5. It is common enough so parts and full replacements are easily available.
In most cases there is little or no need for calibration, as long as you aren't trying to fit a multicylinder carburetor to a single cylinder engine, or a two stroke carburetor to a four stroke engine - but there are exceptions of course.
The 220 Volt sockets on your generator suit a US 220 Volt plug, the 220 Volt, 60 Hertz electricity it supplies is quite near enough to suit our 240 Volt appliances. The engine probably runs at 3,600 rpm to give 60 Hz power, where we run the engines at 3,000 rpm to give 50 Hz power, but for simple outdoor work this is not usually an issue.
To find out what is causing the problem, you might begin with your short adapter lead, inspecting it carefully. Test the drill itself in a normal 240 Volt 50 Hz wall outlet and see if it works properly. If the drill is OK, and you can't find a fault in the adapter lead visually, it will have to be tested with a resistance meter, wiggling it around to see if it is shorted some or all of the time - it probably is.
I'm sorry I can't give you detailed instructions on sorting out the wiring, but frankly, unless you and everyone else who might read this are electricians or have considerable experience with 240 Volt wiring and understand the rules, someone might get hurt. That generator is easily capable of electrocuting you.
