    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    Update on this saga. Run 1 - with carb cleaned and in again, she runs albeit revving really quickly from start she cut out, consistent with the Accel pump being non functional. (2 days ago) Run 2 - Changed oil and filter with 1 litre of yamalube. Dipstick shows halfway - didn't want to...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    I’ve had good results with StaBil in my other engines. As understand it European fuel regs mean that suppliers are required to add detergents and some other stuff at the pump. So you don’t see people here using SeaFoam for instance. At least, that’s what I heard.

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    But what servicing do you really need to do? Empty the bowl if it starts to fill up with water and replace the filter once a season to be safe? In a dry climate with ethanol free fuel I’m sure it’s fine without but the climate here is extremely moist, often with wide temperature variance, and...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    Thanks jgmo. I got the throttle cable nearly to have full range but not 100%. I initially thought the cable was the issue but as you said earlier it’s the piston getting stuck in the accelerator pump circuit appearing to be the problem. I’ll order a new cable as well, it could well be...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    That’s interesting. Your method would ensure the accelerator jet would always be pumping right? Just bunging in a new carb seems simpler though. I still have my timing belt and thermostat to replace. And then the valve lash. Earlier this year I noticed the compression (from cold after water...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    Well, I managed to put everything back together. Sort of. I don’t know what it is with Honda, adjusting or serivicing anything is extremely fiddly and awkward to access compared to my Yamaha and Tohatsu. No matter how I adjusted the throttle shift cable as according to the shop manual and...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    And according to the German SVB site parts finder mentioned in my original post .. the jet set part number for this carb (G11) is … 16150-ZW9-G01 Which is #42! So the mystery is solved. I already have the latest version of the carburettor, which is “post 2012” according to SVB even though...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    I was just looking for prices for a new carb - going by the latest 16100-ZW9-G11 part number as the older 16100-ZW9-816 version is hard to find … And I come across a website with this photo: That’s “14BA” …

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    JGMO; I presume 9.9 is the 10HP model, only the sticker is different. My 2001 copy of the carburetion manual (I only have Chapter 7) states that Jet #42 is used in: BF8A** BF45A BF50A BF75A This old version doesn’t have the newer D range (these were in 2003), what does yours say? I am citing...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    Hey, thanks for the advice again! Hope you had some fine sailing this season. I disassembled the carb according to the shop manual. Everything on my carb seems identical to the shop manual (which is from 2003). I found the accelerator pump nozzle and indeed it was blocked! After an hour...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    Well jgmo, I’ve finally got around to removing my carb for cleaning with the ultrasonic and carb cleaner. I have the jet set and gasket set you recommended. I was wondering, what is the deal with the accelerator pump? How do I know if I’ve got it perfectly clean, or is there a way to...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    Yeah, nothing came out of the carb. I figured this was because the mechanic let the motor idle out, but who knows. So it seems like the only differences regarding the carb is the idle screw? In the US they remove the slot in the screw and in the EU they seal it off entirely? "Will no-one rid...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    Hi Jgmo, Thanks, great tips! As it happens I have a PDF of the 2001 BF8D/10D/etc Honda Service Manual. This includes a very detailed description of taking apart and cleaning the carb, amongst other things. Flicking through it everything seems identical to my engine but I do need to check...

    2007 Honda BF9.9/10D - Replacement Carburettor Confusion

    Hi All; I am in Europe (Ireland) and I have got a second-hand 2007 BF10D for a sailboat. This would be exactly the same as the 9.9 in the States - well, that is what I thought! VIN is BABJ-1306966 The other ID plate says it is 2007, BF10D (HNX0222G0) This is a tiller steered, electric start...
