If you mean 3-4mm short, IMHO, that's huge. I tried to find the gap recommended by Pazon but could not - have they told what it should be?I would turn the engine where one valve is just opening and then backoff that rocker adjuster to release the pressure on the cam. Then you can see how far in and out the cam moves. On a MK3, it shouldn't be much - not sure how much but if a lot then maybe it will lead you somewhere.BTW, Tri-Spark requires 1.4-2.6mm between the rotor and back of the Tri-Spark stator. Sounds like you would be WAY, WAY too far in to run Tri-Spark and I've never personally come across a Commando that won't work with Tri-Spark.
