Think you are right Mick.
If the level plug was 1/4" lower the chain would not be drowned in oil causing the problem
Happy days.

Thanks Simon, as I have the engine oil tight I can go back to the old adage for the chain case, when it stops leaking put some more oil in.

I am obviously missing something here, but unless the chain case has only half the level of oil in it down from the level plug, the oil is lost while running, I don't lose anything when the engine is stopped.
Have I missed an oil seal at the back of the chain case, if I have it was not there when I ...

Has anyone got a crank locking tool for sale or hire, Draganfly are out of stock.
If you also have an extractor for the flywheel end covers, I would also be interested, but Draganfly do have these in stock.
I could make them but it will save a lot of work, here's hoping

Blue Locktite (medium strength) works, But I like a tab washer, easy to use and they do what is asked of them.

It never occurred to me the holes would be at an angle, on checking the four of mine drilled with a single hole, they were all at an angle.
Thanks for the head up on this.

Thanks for your efforts Paul, much appreciated.
Thought there should only be a single oil hole in the rocker, my machines top end was obviously built from a box of bits.
I have a set of 8 with no holes, the same profile as the 4G ones in the picture, going to get 4 of them drilled

Thanks Paul
What does P19 refer to, I can't find any links.
The Ariel manual !948-1958 shows a central drilled hole, also details of how to solve over oiling etc. so I assume they should all be centre drilled, and no others

Can anyone advise which are the correct rockers for a MK1 with regard to the oil holes drilled, or otherwise.
I have 5 variations on mine out of the 8, is this a record for different rockers.

No holes
Drilled center rib
Drilled center rib and short side
Drilled center rib and long side

A bit late on this, but I have just had a stuck inlet valve on my MK1.
Having rebuilt the engine bottom up, I started having problems with number 2 firing or so I thought, it proved to be the inlet valve sticking open.
On inspection the rocker was different from the others, did not have any oil ...
