After attempting to start, withdraw the sparkplug and check for traces of fuel. If fuel is present then the spark plug is suspect. For the inexperienced, the best way to detect whether or not it's working is to buy a spark detector. This sort of thing:
Genuine Briggs & Stratton Ignition Spark Tester

If the plug is wet with petrol, you are over-using the choke. The remedy if you think the engine is flooded after a starting attempt, turn the lever from "choke " to "run" and turn it over a few times with the throttle fully open, then try starting with no , or half-choke.
Those are the first few steps for any small petrol engine. There is a forumite (Steve66) who is a consummate expert on this engine, and will, no doubt be along shortly with advice.
There is someone on the forum who can supply a better set of bolts to replce the ones on your engine that have rusted to death. you can find out via a discreet PM

Honda 2.3 advice
Honda 2.3 - Fine apart from....

wow! thanks for the very fast and full response - I will follow up on the points you have raised and will post the result.

I've just had similar problems with Honda 2.3, Honda lawnmower, strimmer and small generator. Turns out to be old fuel - cleaned out all old fuel, cleaned carbs, new E5 petrol AND Honda fuel stabiliser. All now start easily and with more power - I can barely keep with the mower!

Seem to recall that there is sensor to confirm that there is sufficient oil in the engine. No oil, no start.
Engine oil can easily leak out if the engine is stored on it's back and on the wrong side. If stored on its side has to be on the tiller handle.

Yes the correct side (down), has little vestigial 'legs' that serve to keep the casing from coming in contact with the ground.

Hi, was the new carb a genuine Honda or Chinese copy?
Have you been using Aspen in it?
When did it last have a major service including valve adjustment?
TCI (coil) units very rarely fail on these engines

 

[colhel]

Is the kill chord attached?

 

[Hanibal]

This is a compound response to those who have commented - Thanks to all of you.

Petit fleur- new fuel - new carb - sparkling clean

Bav32 - Plenty of correct oil.

Steve 65- No Honda Logos so presume "other" brand - Don't know what Aspen is - Not sure when last service was done - I have just acquired it as a failed project from a friend who said it sparked but did not run. I will read up on Valve adjustment but there is compression.

Colhel - I have tried it with kill cord connected and disconnected (as advised by others)

General note - my computer keeps warning me that this site is insecure?? anyone had any problems?

You might find it better to use Aspen 4 synthetic petrol as it has a much longer shelf life. Ordinary petrol now has a shelf life of about 3 months, whereas Aspen has 3 years. Very useful for rarely used small engines like outboards, lawnmowers and chainsaws.
Aspen 2 | Aspen 4 | Premixed Petrol | Aspen Fuel

Thank you Concerto; if I manage to get it going I may consider a gallon of Aspen

I think you will find that our Honda 2.3 Guru - Steve65 , is very much against Aspen fuel which can cause engine damage.

[Hanibal]

stripped the engine down today checked the valves found all ok - put in another new spark plug used the hairdryer on the coil pack and actually got a spark - then stripped the new carb full inspection of fuel lines and jets - polished a few mating surfaces and fitted new gaskets. leaving it for the evening to let all the cleaning fluid to evaporate and will reasseble tomorrow and give it a go - watch this space

 

[fastjedi]

Does it start if you inject a bit of fuel through the plug hole? The valve clearances are tiny. The smallest amount of wear can result in the valves not opening

 

[Hanibal]

I confirmed that the valves are operational - we will see tomorrow if it can be brought back to life

Interesting, I have heard a lot of good things about Aspen. I wonder if @Steve65 would care to post his opinion on the product and the damage that it can do to engines. I'd be interested to hear if it is specifically issues with the Honda 2.3 or all outboards.

Me too Sandy.
Have a flick through this thread. Seems to affect 4 strokes more

"I havent much experience with saildrive outboards compared to conventional. What I do have lots of experience of is repairing outboards that have been run on Aspen.

GREETINGS

I am feeling very pleased with myself - I have just rebuilt the motor and did a bench test - Very happy to say that it started first pull and idled very nicely too.

I warmed it up with the prop in water up to the cavitation plate and as soon as I put the choke in the prop stopped turning and it idled nicely .

I do not know what the correct carb settings are - I did it by ear - any advice very welcome.

I did not have SAE 10-30 engine so used ultra synthetic SAE5-30 BMW oil. Seems OK to me again any advice welcome.

Best £50 I have ever spent!

Happy Hanibal

Me too Sandy.

Thanks, the date of the thread was when I was enjoying my wee trip this summer enjoying tee shirt sailing until we arrived in the English Channel.
