Ive done a deal for my new Kipor generator , thanks to all who helped me choose /forums/images/graemlins/smile.gif

Now the little hick up, its a four stroke /forums/images/graemlins/frown.gif
I already carry on board 3 gallons of 50:1 two stroke petrol for my Tohatsu outboard, I dont want to have to carry separate fuel so I presume I can use the two stroke mix (only got a splash of oil in it) for the Kipor.
I know it will be slightly under power so I got the 2.6 kw model.

There isnt a catalytic converter to gum up and I can change the spark plug once a season, is there any other reason why I need separate fuel ?
 
carry straight unleaded and add the 2 stroke oil prior to filling the out board /forums/images/graemlins/wink.gifput the unleaded in the genny
you know this already 'cos your the man /forums/images/graemlins/laugh.gif
cheers Joe

No probs, give it a go if you find you're clogging the plug(s) with oil just clean it and have a rethink.
 
Thats what I thought, its got a years warranty on it.

Cheers Joe but once I add 2-3 l , i dont know how much is left in the can so it would be a guess of a splash of oil. /forums/images/graemlins/confused.gif
 
Pete
add it by the litre plus a splash(measured) of oil thats what I use to wiv' me bikes
1 litre jug(Tesco)plus small marked measure cup for 2 stroke
cheers Joe
 
I will change if it needs un oiled fuel.
current method is just to buy exactly 5L and tip in measured oil (marked on coke bottle) so zero mess, the 5 l gets added to the 3 gal tank so only ever one petrol tank on board, my plan was just to connect the remote outboard tank to the genny.

i could run the tohatsu on 100:1 as it is a 9.8hp and we seldom use it above 1/2 revs. but that is out of warranty.

i can use 98ron to increase octane levels

If I need neat petrol I can carry extra , it would have been much easier for the two to share the one tank.
cheers

As others have said, quite rightly, not a good idea. I carry around 5 gallons of unleaded and only mix the 2t when needed.

I bought one of these and one of these to make life easier. /forums/images/graemlins/grin.gif

That's the answer run a high spec 2 stroke oil at 100/1 and chuck it in the Kipor(jobs a good 'un)

Cheers Joe

[/ QUOTE ] There is no facility to connect a remote tank to the Kipors. The onboard tank on the IG2600 and 3000ti hold just over a gallon (4.8l) and this runs the genny for 4~5 hours.

BTW, All of the suitcase type "silent" (read quiet) gennys I have looked at run on unleaded.. It appears only the "cheap and nasty" (read noisy) open frame gennys that use 2t.

Why not? It's hard to see what possible harm it could do.

Can you explain, maybe there's something I haven't thought of.
 
I used up last years left over outboard 2 stroke in the 4 stroke lawnmower - cos I'm cheap. It worked but only short term and it deffo wasnt a way of operating long term. It carboned up the plug fairly quickly which in turn made the mower more difficult to start, refusing altogether after a while. It also carboned up the piston and valves and clogged the small jets in the carburettor.

Obviously the results will depend on the characteristics of the engines involved, but you can certainly expect more problems with the genny doing what you propose all the time.

[/ QUOTE ]As explained above, coking up of the valves, coking of the combustion chamber, fouling of the plug (OK you could fit a hotter plug) possibly blocking the carb jets and airbleeds as the fuel evaporates and leaves the oil gunge behind, gumming up of the rings. - I am sure I can think of a few more - One more - wrong fuel - warranty void.

I'm not convinced any of these are significant problems for obvious reasons. Perhaps the best option is keep an eye on the plug - if it repeatedly gets oiled or really badly coked up just start carrying some oil and mixing for the OB.
 
Another problem, 2t petrol will cause a 4T carb to run a bit lean, because the petrol is 'diluted' with oil. On a modern engine designed to run very lean for economic/ environmental reasons, this could cause overheating and valve problems. Plus all the carbon and mess mentioned by others....

Don't be too disparaging of the cheapos Cliff .....I have been jolly grateful of mine a couple of times when I've flattened the batteries with eiither the heater or the computer. /forums/images/graemlins/grin.gif

I am not knocking the little "cheap and nasty, noisy as hell" 2t open frame gennys - they do serve a purpose - they would make a good "emergency" genny for, as you say, the few time you flatten the batteries and are great for running small power tools when working at the boat when there is no mains supply. They are not so good though for frequent daily use. They do have some advantages over the more "upmarket" varieties like they are cheap so no big loss if it gives up the ghost, they are generally lighter than the suitcase type and easier to "tinker" with if something goes wrong.

Two disadvantages though are the cleanliness and stability of the output (don't run anything electronic from one) and you would be as popular as a turd in a swimming pool if you ran one of those for any length of time in an anchorage where other boats were nearby trying to enjoy a little "peace and quiet". /forums/images/graemlins/grin.gif
