Should be a fairly common coil. Um off hand i don't remember what the coil in my 2s looks like but you may have some joy if you google for a villiers parts supplier as jap and villiers were one and the same in later years. But the parts would likely have to come from the uk then...

how'd you damage it?

Hi and thanks for your interest

I got both engines for a half year ago but haven’t got the time to take a look at it before now.

It was broken from the start of my ownership. Nothing last for ewer.

But I have another problem, I can't get the govenor and carburetta fixed togehter. I have to make a new conection between them. It it passibly that you would help me with a pair og pictures og that. The govonor had an angle and I don't know if it fits in the one or the ohter way. It can point away from the engineblok or away from the Zenith carburetter. That will be a great help to me.


Have a nice week end


Defess

Hi. Um what carb have you got? The 2a and 2s were slightly different, typically different carb but that depends on age. And different horsepower. But i'll look at my end and see what i can tell you and take a photo.

Hi, its pouring with rain and the engine's in a shed outside so i can't take a pic right now , but here are some older pics, unfortunately not very clear and the engine was rather dirty. This was when we first got her. i'll try take a better pic tom.

your carb is the same as ours though. do you need a manual? i have an electronic one for that engine.

Hi Defess, I am enclosing a couple of pics of my 2A, with JAP carb, to show the linkage. There are several holes in the connecting link to enable you to alter the butterfly travel, otherwise it will rev its head off! For starting the butterfly needs to be open which on the JAP carb is the lever vertical, and the governor rod fully anticlockwise. Fine adjustment can be done by altering the spring tension.
I hope that these are helpfull to you.

Hi


Thanks for the pictures. I have a question.
What do you mean by this: "otherwise it will rev its head off"? Will the governor be damaged or?

I will upload a few pictures of my engine, that will help I think.

Do you know the place http://www.villiersparts.co.uk/ ? I think you all do but I never receive any answer to my questions? Well I will try again

Sorry, by "revving it's head off" (English expression!) I meant that it would be running at maximum revolutions which uses a lot of fuel and is also rather noisy. If you are running it for shows etc then a nice steady speed is satisfactory, just fast enough to ensure adequate lubrication and cooling. My 2A will run happily all day at shows driving a small water pump, around 1,000 revolutions per minute is fine. The more stroke that you give the carb then the faster it will run.
For a coil I should look on ebay United Kingdom as coils and other JAP parts appear regularly, the military used a lot of these engines although mine came off of a rotavater. I am unsure as to wether Villiers parts are the same as I have not had dealings with Villiers engines since my motorcycling days in the '60's.

Hi and thanks for the photos and for the school in English. I was just wondering... Now I can show you photos of my 2A without the Zenith 12T Carb. Maybe the governor connection isn’t original. It is definitely different from yours.

Default Re: J.A.P engine 2A coil damaged

I will try to make my own thing for the spring like the one at the picture (green circle). Is it possibly to make a photo of that thing and write down a few data of it? Distance between the holes and end to end in mm (millimetres) or inch.
I would like the same of the thing that connect to the Zenith carb.
What is the red thing in the blue circle?

Thanks a lot for your help

My photos aren't very good but they may help you. I think that your engine was a special application model with a variable governor setting, possibly a battery charger, I have seen something like it elsewhere.
Anyway, the "red thing in the blue circle" is the ignition cutout button to short the mag out,(they are often missing), the link to the carb is 1 3/4 inches long and about a 1/4 inch wide with a few 1/16th holes in it, the other bracket which is where you tension the spring is 30mm long with a 1/4inch hole one end where it is bolted to the crankcase and a 1/8th hole at the other where the spring fits, it is cranked as well. The only way of altering the speed is to tension or loosen the spring by moving the cranked bracket.

Hi

I have a Zenith carburettor for my J.A.P 2A engine but I need a picture of the gas throttle that is placed on the a... God this is difficult to describe. HMMMM. There is the governor and the connection to the carburettor. The thing were the connection is placed on the carburettor is called the throttle. The thing, at the throttle, is connected to the bar and later on to the governor. That thing is missing on my carburettor. Do understand a bit of what I try to say? I don’t I need a picture of that with a few data. Length and distance between the holes and the angle of it. Then I have to make it on my own like I did with the connection to the governor.


Thanks for your time and help
