Advancing the timing makes a big difference as well.

Not sure if you are commenting about WYKs post or not but if you are, the "tonsils" he is on about is the support that drops down from the roof of the inlet port. This protrusion generally is used to stop the ring entering the port and wearing the edges or snagging in the port.

 

What he is saying is that if you have ground it out then ensure the port edges are bevelled so the rings don't snag - good advice IMO and with all porting - time should be spent re-bevelling the edges of the port to avoid snagging of the rings.

 

If it wasn't this then....what??

Here is a good one . If you are prone to drop it on its strop then make some kind of limiter between the two halve of the saw so that you don't bend the lower AV spring to almost a right angle . Spark screen out strait away !
