Wolseley WLB 9

Hi All

This lady gave me mag problems but that is all sorted now.

Now I can not get her to run slow.
I have turned the regulator in both ways, still runs very fast.
I have checked the governor and weights all looks fine and good.

Anything else it might be.

Thanks Raymond.

I don't know this model, but surely this must be a fuel issue.
Speed is goverened by fuel/air mix flow in a petrol engine. The governor "measures" the speed and regulates the carburettor flowrate to adjust it. And in most carbs, its the air flow rate that's regulated, and fule just flows to mix with it. So the air flow rate is the real factor that regulates speed.
You say the regulator seems to be doing its thing.
But logic suggests that:

• Either the regulator isn't "measuring" right (in quotes, as it doesn't measure, it just forms a linkage between speed and some connecting device to the carb).
  

or the linkage doesn't work or is out of adjustment
or the butterfly in the carb isn't moving right
or the non regulated airflow controller (might be another butterfly, or stops of the one that governor links to?) is set wrong.

It is unlikely to be a spark / ignition issue.
Its not going to be a valve timing issue.
It could possibly be a fuel type issue? (but unlikely, unless you mixed in some weird brew of something else combustible)

My tuppence.

or......
its a high horse power high rpm engine
for example my wd8 is 2.25hp @900rpm as appossed to the norm of 1.5hp @700rpm
the only way I could reduce the running speed on mine was to take off the valve cover plate, remove the split pin on the govenor control threaded rod, remove the rod, drill another hole for a split pin closer (but not too close) to the end of the rod, then put it back together using the new split pin hole.

What does your engine plate say re hp and speed?

There is an adjusting bolt on the end of the governor arm, you could try and screw that further towards the governor to stop it opening the butterfly as much. Dan

tried that first on mine Dan, didn't help much, the trick is to take some tension off the spring

I did a combination of the two on my wd8, It is a 2.25hp and when I got it she came with another scrap wd8 which was 1.5hp so I swapped the spring. As you say the bottom screw didn't make a great deal of difference but it did slow it down a bit.
It might be worthwhile clamping two turns of the spring together with a piece of copper wire temporarily to see if it makes any difference. You can then look for a lighter spring.
