I have monkeyed about with the valves again and set them to 0.1 as opposed to 0.05. Could this be my problem as its such a power difference I am not not sure just this could be the factor.
Setting the valve clearances is quite straight forward, the valves should be set when the engine is cold, and when the engine is at TDC (Top Dead Centre). TDC can be set by turning the fly wheel until the timing marks line up. i.e. the 'T' is aligned with the pointer on the engine case.
Then remove the cylinder head cover and ensure the camshaft timing marks are ligned up with the edge of the engine casing (red arrows), with the large hole in the cog away from the engine(yellow arrow)
With the timing now set, and the head cover removed you will have access to the tappets (used to adjust the clearances). The tappets are made up of an adjuster and a lock nut.
To set the gap we have to loosen the lock nut, set the adjuster using a feeler gauge, and then tighten the lock nut WITHOUT moving the adjuster. The gap should be set to 0.05mm for both inlet and exhaust valves.
I have no idea where billy green's post on valve setting has gone so I have re-posted it.
Now 0.05 might sound pretty good to you guys but Im still trying to work in thous of an inch metrification stuffed every thing up. In the old days I used to use the blunt end of a hack saw blade as a feeler guage and it worked for me then and still does today to set the gap on my spark plugs.
anything the mind can concieve and believe it can achieve

Call me dumb, but can someone please explain where exactly the gap is supposed to be? Is it between the tappet and the valve? Also, is it supposed to be 0.05 or 0.05mm? (My feeler gauges have both markings).
