Re: Little Model Forty F (1949/50)

My original posting on this topic was an attempt to find out how many Little Model Forty F of 1949/50 exist. This followed my recent acquisition of F201. Does anybody know how many exist? Thanks for your comment, Oyster, on the problem of finding an original spec Amal carb for the F. I still don't q...

Re: Little Model Forty F (1949/50)

Oyster,
I don't know what a 102 type inlet is. The F inlet is just like the FV, SJM and the other 40s. The only difference that I can see on mine is that the inlet bore is a lot smaller at approx. 0.37 dia. The O/D of the inlet stub is the same at 0.75.
Have I got the wrong end of this?

Re: Little Model Forty F (1949/50)

Collector Inspector,
I would really appreciate information on the model number etc of the carb that was fitted to the Anzani Pilot.
Was it exactly the same one that was fitted to the Little Forty F of 1949/50?
Do you think it was fitted to any other engines?
Thanks for your help.

Re: Little Model Forty F (1949/50)

Thanks Charles for the clarification concerning gear ratios.
With all this information that you have - when is the book going to be published?

Re: Little Model Forty F (1949/50)

Chris, Just been measuring the F and FV cylinder heads. They are completely different and not interchangeable. In the horizontal plain the stud holes centre distance is 2.10 for the FV and 1.87 for the F. The widths of the block and head are also different. 3.59 for the FV and 3.35 for the F. Are yo...

Re: Little Model Forty F (1949/50)

Chris, Thanks for your reply. What serial number is yours? Mine is F201. I might have a sevicable head from an FV. I have not yet checked to see if the stud positions on the F are the same as the FV. The cylinder block dimensions on my F are smaller than the FV, so thinking about it now, the FV head...

Little Model Forty F (1949/50)

I have just acquired a Little Model Forty F. Charles P has given me some information and help concerning the model - thanks Charles. I am interested in how many of this model are still in existence and whether owners would like to share their knowledge, problems and difficulties with this model. Som...

Re: Little Model 40/model 40

Yes, although I have very limited knowledge of other models, I really like my FVs. They are nice and light and power my inflatable dinghy and my small pram dinghy very satisfactorly. Although the short central tiller looks unusual, I think ithe design works well, although the throttle cable routing ...

Re: Little Model 40/model 40

Yes, but which is the most efficient/powerfull? Staying with the cute angle - I think it has got to be the 3 or 4 bladed cloverleaf - but which one?

Re: Little Model 40/model 40

Yes, I have stripped three drive shaft tubes off the pump housing. One just unscrewed without any trouble, another took a lot of effort, and I gave up on the other one as the end thread of the tube was damaging the thread in the housing. I always wonder what the 'best' prop is for these FVs powering...

Re: Little Model 40/model 40

Thank you Charles for that information. I thought that there might be a greater difference.
I think the small light FVs (and Fs) are just right for a small boat tender.
Thanks again.

Little Model 40/model 40

As an owner of an FV, I am interested in the slightly older F.
Can somebody tell me how an F differs from an FV.
Thanks.

Re: do plugs wear out?

I would think that once a CLEAN plug fails then it is going to continue to fail if it is under the same running conditions. Likewise, I would think that if a plug in a specific engine is working well, then unsurprisingly it will continue to work well for a time. The timescale to failure might well b...

Re: do plugs wear out?

I have always assumed that the ceramic insulation breaks down. I thought that the surface of the insulation developed small cracks either running along the surface or through the insulator itself. Once these cracks contained a conductive material then this would aggravate the situation and poor plug...

Re: Forty Series Tank Transfers

Charles, Thanks for your reply. I will order a 'sailorman' transfer from John. This time I switched the lights on in my workshop and can state quite clearly that the previously silver flying seagull is now white! Sorry! Even with the lights on, the old gold one still looks gold as per the lettering....
