Why not it has not given me any problems leaving fuel in the carb, usually starts on first pull. I don't drain the petrol from the injector system in my car nor do I drain the petrol from the carbs on the motorcycle. where does it say one procedure benefits the other. I don't use them every day probably weekly.

Wishful thinking on the salesmans part i reckon. I bought some new rocker covers last month from Honda and they were exactly the same as previous. As far as i know the spec hasn,t changed.

It did sound too good to be true! Been looking at 2.5hp's and with strength of pound prices for Mariner/Tohatsu/Mercury and Suzuki have all plummeted - many for sale at under £500 now, which is over 10% cheaper than a few months ago. Curiously though, Honda and Yamaha prices have remained high, and mostly unchanged.

If you can get a Tohatsu based 4 stroke for under £500 that is a tremendous buy. Incidentally i had a guy telling me the virtues of Selva yesterday. He was trying to say that a 2.5 Selva was much better value for money compared to a Honda , Tohatsu Yamaha etc even though its more expensive, less warranty and terribly complicated. I know you owned one, did the oil injection make it smokey?

The Selva wasn't smokey, but was the worst outboard I have ever bought. Fortunately, after long email trails and lack of responses, I did get my money back. The Selva is horrendously noisy - much much more so than the Honda. The other issues are that there is no fuel tap, but a diaphragm carb, which means that you can never run it out of fuel and empty the carb to try an prevent the jets gumming up. And the carb will essentially contain two stroke petrol, which will go off quicker. And the centrifugal clutch is simply awful - it takes up at much higher revs than the Honda, and it is impossible therefore to run the engine at a trolling speed - its on or off. Even the Hangkai clutch is better! On mine the clutch totally disintegrated after two months with the result that the engine was beyond economic repair. Someone in the trade told me that Selva didn't actually design this powerhead, nor do they make it. They are buying these engines as stock from a third party, presumably from some company in China.
They also run much hotter than the Honda. The powerhead is supposedly air cooled, hence the vented cowelling and high noise. The exhaust is water cooled from an impeller. However, when the drive isn't engaged, the powerhead itself very rapidly heats up, unlike the Honda, which can idle in neutral indefinitely, and I have never heard of a Honda overheating?
To me the Selva engine looks like a good idea in concept, but failed in execution. Its like being sold a prototype. For those motors that do survive clutch failure, I think there are likely to be long term issues with bottom and top end wear, as being a four stroke, lots of moving parts, but not a lot of oil in there to smooth them!

Thats more or less what i said to the chap.Diaphragm carbs, i have one ready to be fitted to a 2.3 Honda for a trial.It will be fitted with an inline fuel tap ut im not sure if that really matters. I have a Honda gx35 strimmer with a diaphragm carb. I literally just pick it up and start it just prime the bulb and away you go. I never have had to put a screwdriver on it (jinxed myself now!). The added advantage is they are completely alloy the disadvantage is i dont know how long the diaphragm will last.

Selva is not so clever - primer bulb is under the cowell, and you can't get to it without removing the hood - which also requires you to remove the fuel cap. So to prime the Selva, you have to remove the fuel cap, and then the hood - prime, and then put it all back again. Great design thought process there!
Diaphragms usually fail if they dry out over a prolonged period - so guess you need to keep using it.
I have had a strimmer fail, unlike yourself - maybe because I bought cheap! The rubber on the fuel pipes and bulb don't like ethanol - which of course the current issue for many small engines. If you put rubber into ethanol, it eventually disintegrates (like one's own liver!)
