2-stroke mixture
I have a generator (cheap end) never used for 7 years so going to get it
working and sell on. I only intend to mix up a ltre of petrol to a small amount of oil for the 2-stroke mix. Just to get it working for test purposes. For my purposes could I use either oil I have for the car or some oil I have for the chain saw. for my short running time would the oil be that important? |

Ermin laid this down on his screen :
I assume the chain saw oil is proper 2 stroke oil so that is what you should use. Chain saw oil is the sticky oil, intended to stick to and lub the chain as it flies around, wrong stuff for a two stroke. Car engine oil at a pinch is better than nothing. |

No. a lot of 'chain saw oil' is in fact oil for the chain, not the engine you can get a tiny little capsule of 2 stroke oil to mix with 5 litres of petrol https://www.amazon.co.uk/Makita-P-21.../dp/B0069R45IQ -- €œIdeas are inherently conservative.

Its very different to 2 stroke oil and I wouldnt use it in place of 2 stroke oil. |

Speed blabbered, again: I assume the chain saw oil is proper 2 stroke oil so that is what you should use. Not if he is talking about chain oil. Its very different to 2 stroke oil and I wouldn¢t use it in place of 2 stroke oil. The answer was already provided by several others.

Cheapskate!
Besides there are rumblings that this sort of engine will be outlawed for pollution reasons pretty soon so I'd shift it before that happens!

I have one of the smaller (600VA?) ones that seemed quite popular a while back that is definitely a two stroke. The 3kW is a 4/ and Honda powered. ;-) I also have a little 12V 2/ genny and whilst it 'ran' the last time I tried it, it wouldn't tick over (or even run a lowish revs) very well and that was probably down to crank seals. ;-( I gave my other 3kW genny (Honda clone powered) to a mate and he keeps it in and runs it from his van.

I think that all of the cheap generators that I have seen have been four strokes (copied from a Honda engine). Just saying. The cheap ones, around £100 or less, tend to be 2 stroke. There are a number which are 'badged'- typically 650-850W, with a petrol tank make of pressed steel. They often have a 'cup' under the petrol cap to measure the oil/petrol mix and the correct mix is marked on the tank (from memory 50:1). A four stroke will have somewhere to fill the 'sump' and possibly a drain plug for same. The small Hondas don't have a drain, you tip the beast up and pour the oil out of the filler. Chain saw oil is the last type I'd use. Engine oil perhaps but the proper stuff isn't expensive and why risk wrecking the engine? Chances are the air filter has dried out. These are normally the foam type. Wash in soapy water, rinse, squeeze, let dry. Then add just enough engine oil to make dampish. If it was left with petrol in the carb, chances are it will need cleaning out. You may be lucky or you could try one of those sprays and some 'carb cleaner' in the fuel. -- Smile for the camera ;-) https://www.youtube.com/watch?v=HxyL2_38EsQ Remarkable Coincidences: The Stock Market Crashes of 1929 and 2008 happened on the same date in October.

I have one I used to use charge batteries but I've now got a 4 stroke invertor one which runs off propane (or petrol). The 2 Stroke one was under £100 new, the 4 Stroke nearer £1000.

Cheers, T i m I don't know about small generators, but why would a simple generator have a tickover speed, even on low or no load? It needs to maintain a frequency of around 50Hz, so it needs to run at around 3000 rpm (for a simple two-pole generator). SteveW |

If it's a simple alternator it has to run at 3000 RPM to produce 50 Hz output - no reason for it to run at any other speed. It's not smart smart enough to idle until something starts drawing current, although there may be a manual switch to do that. |
