Marine two stroke pumps must be similar to what are used on motorcycles. On my FS1E and RG500 the oil pump output can be calibrated using the procedure set out in the service manual. On the Fizzy this is done by adjusting shims which must vary the pump stroke, I forget about the Suzy.

You could also switch brands, the e-tec oil must be brilliant. Maybe there's a difference with marine two stroke which might be a different spec because the engines will run cooler than with an air cooled engine?

There's never any harm in some fogging oil and wd 40 before a long winter.
I've got an etec - they do the fogging for you, it's just good practise if you're not going to use the engine for 6 months.

Bizarrely every manufacturer disagrees with you (Barrus agree so much they have a special function on the Etec to oil the cylinders for you!). Anyone reading the thread will now know to avoid engines you've used - you don't flush the cooling circuit, don't protect the cylinders from condensation/corrosion, stabilise the fuel* nor change the gear box oil. The first three are a 15 minute job.

*my preference would be to drain the fuel and use fresh - but since you left the carbs full, I guess your preference is just to neglect it.

A large amount of smoke and excess oil is common / to be expected if you had put a tea spoon of oil in each cylinder as usually recommended, and disappears after a while.

Poly.... How many engines do you have. I have 10 marine to look after., 6 car, 40 + model aircraft, 3 motorbikes and some 8 other engines. I am afraid I don't have time for pointless work


As for people avoiding my engines I could not care less as I hardly ever sell anything. I tend to Buy not sell


As far as the other points you raise you are in error.


I always flush my engines in fresh water after use
I put Stabil in the fuel
I Change the Gearbox oil as necessary
I Change the Impellers as necessary
I change the Spark Plugs as necessary

If you just have one small engine to attend to then treating it with kid gloves is fine. I am certain I have far more experience of this sort of thing than you.

I have received satisfactory answers from the experienced and non theory wallers and I am now very happy. I also have replacement parts on their way to fit (which I will do myself) should the conclusion I have reached be incorrect

Carry on posting however as I am sure you will

What answers have you had, apart from the basic common sense stuff that an expert such as yourself would have known anyway? Iím genuinely surprised that thereís anyone with more experience & expertise than yourself. In fact Iím shocked that you needed to ask about such a trifling matter in the first place.
