Vacuum advance is an economy device, mechanical advance is what gives the performance.

You're confident doing that without load Hope you find the trouble in the end if there is anypilkie said:When standing it will not rev above 5000,,well only for a split second it goes to 5500 on initial flooring of the throttle,carb butterfly is opening fully.
It seems free enough on the revs up to that point though!!
Its as if a rev limiter kicks in!

Nope! It didnt get above 70 even downhill,nor coming back either!DaveHerns said:What was Nick Dunning's opinion on it's performance ?
Unfortunately Nick was busy, so he didnt get a chance to have a spin.

Presuming that the tachometer is correct, it should easily take the needle off-scale when you floor the throttle in neutral.

Have a bit of respect for the engine please .............. That sounds brutal
pilkie said:Right,,, little bit of an update.
When standing and revving gradually,the counter goes up evenly 1,2,3,4,5000rpm,but sticks at 5000rpm,although the engine clearly IS revving to beyond this point!!!
If you floor the throttle it goes up to just over 5500 then drops back to 5000,so I suspect the rev counter has a fault showing high revs.
I was gentle,ish!! :wink:
Back to the performance!!!
It seems quite good up to 50-60 then it starts to struggle!

And they have been known to break the camshaft when doing that.

and when you take them out ... put them back in the same order, there is one thick one and one thin one. I forget which goes on the top/underneath, but do it as per the book.
