I have a small villiers engine and it was running well until I gave the
whole thing a wash. Now it has no power.
Could some one tell me if you were to start from scratch who would you
test and tune the engine
Sounds like you have got moisture in the coil.
Take the engine cowling off and blow warm air into flywheel for half an
hour or so - fan heater or hairdryer.
then clean and set the points to 15thou. points should be opening about
3/16" before TDC.
Check there is no water in the carb floatbowl.
Apart from that there's not a lot else to go wrong.
I have the engine sitting in the sun at present. Heres hoping because
it was running very well.
Can you tell me how to identify what engine I have? I have the engine
numbers but I can not find anywhere that tells me what they mean
I may have found the problem. I was checking the the carb. I took the
piston out and when I put it back in I got it 180 degrees out. Because
there is the indent the whole piston and neadle would have been sitting
too high. So I think some of the problem was it was running too rich.
I didnt work this out until I had tried mucking around with the neadle
How do I work out the best height for the neadle?
I checked the gap on the points. How do I check the height before TDC?
Do I have to put a dial gauge into the spark plug hole?
Is the needle secured with a clip in one groove of several? If so, put it in
the middle groove.
That said, I'm assuming you have changed it from its previous setting.
Mixture- I assume it is the little screw in the middle of the throttle
slide type of adjustment- if it is over rich then it will smoke
slightly and not rev fully - screw the needle down.
If it is weak it will pop and bang back through the carb - screw the
Timing- find a long bolt or bit of dowel and drop it in the plug hole
so it goes up and down with the piston - turn the flywheel clockwise
and mark off TDC on the rod with a felt tip, then make a mark 5mm below
that, pop it back in and continue clockwise, when it comes up again the
points should start to open at the 5mm mark, as long as it's somewhere
near it should be ok.
There should be a plate on the cowling to tell you the model number if
it is missing then what are the numbers off the crankcase?
One of the numbers on the barrel is 3812
"One of the numbers on the barrel is 3812 "
I have a small villiers engine ........they were made by J.A.P before
villiers took over.
here it is.its part of a two stroke outboard.
spares for these small engines are avalable from
if it is the one i think it is it is a 38cc type 12
here are the settings
all the best..mark
Sorry to bother you, but we've just registered with ureader and haven't a
clue how to get enquiries like yours into the system, could you possibly
tell us how to do it please?
Hope you managed to solve your problem, but in case you didn't, it sounds
like water has got into either the magneto or the carburettor. A good blast
out with an air compressor might help with the magneto and a strip down and
clean could solve the carburettor, there may be water in the carb bowl
Let us know how you've got on
