lambretta electronic timing errors/inconsistency

[156 D]

Nothing is perfect! ...even replacing a Volvo timing belt...take the belt off with the lines all lined up put on the new one no alignment any more, but it is on in the correct place........The timing marks are only there to ensure it will run after a service or rebuild....whether it runs good or bad is another matter but it will run on the standard marks......anyone who`s anyone interested in engines know`s that the ignition is the heart of the engine, so to those interested in getting the best out of there machines will find there own TDC to make a mark on the flywheel and housing ....forget the dwell....I`m a joiner and in my trade a pencil line is only a guide and not gospel...you either cut to it..on it ..or the other side of it.....so therefore the timing marks are only guides ....this 17,18,19,degrees is only talk or supposition....every engine is different....that`s why the best performing ones are blueprinted....then you are talking accurate degrees.....As you all know the best way is roadtesting, just keep increasing advance until it doesn`t like it anymore then just back off a tad....then what would the degrees be?....you wouln`t even begin to know, but you do know the bike goes like hell and likes it........
