No one mentioned that the mechanical setup does NOT necessarily follow the engine thru the rev up .
The Falkons etc., start low and you simply accept the high - at our altitude -you can bump em a bit -
When we tried the mechanical setups -they worked ok -just a bit dated now.
The Synchro Spark - in comparing - is hard to beat - The extra features in the foreign ones are very nice tho -the tach features auto shutoff etc..
