Master Bitbaltic,

You are a gent. That is what the forum is really all about.

Seconded!

Gentlemen, I read the thread with interest but am still struggling to find the kind of manual that tells you how to take the crankcase apart and change a con rod...

Does anyone have any pointers please?

My child shot mine off the back of a tender whilst it was running and I'm trying to reduce the pocket money deductions!

The workshop manual doesnt show you how to strip it, remove the powerhead and it splits into 3...sump ,cylinder and upper casing. You will need to completely strip the powerhead to replace the con rod. Make sure you reset valve clearances...0.15mm ex and in and also the valve timing is correct

 

[Steve65]

If it was running at a moderate speed when it submerged, it usually wrecks the cylinder skirt and piston

This link now yields a "404 / file not found" result. Is there a replacement link available?

Hi All
There is a reference on here to a doc which I'd put together previously, showing photos for carb cleaning etc.
I've just had to replace the clutch (due to it getting rusted up after a proper dunking)
So I also took some photos of the clutch etc, and how it hangs together, in the hope that this helps some others.
Best wishes

This is an excellent guide - thank you for a) making the effort in producing it and b) taking the time to re-post.

Do you know if the Honda service manual contains anything useful that you've not covered - any previously posted links now seem to dead-end 404...

Ignore this enquiry - I've just seen and opened the Honda Service document linked within your guide. The Honda document, whilst detailed, adds nothing useful to the guide you've prepared on cleaning the carburetor.

Basically these are exploded diagrams of a 2 hp honda Carb. The diagrams show how the slow circuit ans main circuit work whilst running. If your slow running is an issue these diagrams will show you where the blockage will be. Also the same for your main circuit.
Saves trying to explain the boring fundamentals of carburettors

I have a Honda BF2.3 which won’t idle. I’ve dismantled the carb and blown everything through with compressed air which has improved the running slightly, but it still won’t idle. I’d like to remove the idle mixture screw to make sure the passage is clear and to check how many turns it is off the seat but can’t see how due to the restrictive head on the screw - unless I’m missing something?

I recall reading that the idle screw head is "sealed" with a plastic type blob of paint - careful (stressing very careful) application of a heat gun will enable removing the seal.

If you click on the link in Steve66’s post above you’ll see an illustration of the carb including the mixture screw. The head of the screw has a metal “cam” which only allows it to be turned approximately 45 degrees and in my case doesn’t appear to have any effect on the near idle speed that I can achieve. I’m not sure how it would have been screwed in originally!

 

[MickToo]

I see what you mean - it's a cam cover by the looks of it. Possibly simply an interference press fit? The maintenance manual references the stop in the diagram but makes no mention of it in the adjustment details - this would tend to suggest to me that it pulls off the top of the screw... Surely anything more technical would be detailed?

This is from Honda's carburettor manual - the limiter cap is simply shown as a separate piece to the idle mixture screw

This is interesting! I haven’t seen this version of this page previously which shows the cap as a separate component. I did attempt to prise the the cap off, thinking that it might be a cap but didn’t want to force or break anything. Now that I know that the cap is definitely separate, I’ll give it another go! Thank you for this - much appreciated
