Starting in reverse

[Teglease]

Hi' I'm running a sil Gp 150cc engine with a 185cc barrel & 28mm Dellorto PHBH carb, everything was fine until it just started to start in reverse
how the hell do I stop it and make it start correctly ,,,,,, help I can't go to the IOW backwards

.......or get some decent rear mirrors

Happened to a mate of mine years ago
Caused by Change in temperature

Timing is wildly out.

Hi Teglease,
Timing too far advanced.The 1960's Messerschmitt buble car had two sets of points to advance timing so that it could reverse.You had to stop press a button or something and it then used the second advanced points to reverse engine.Fortunately Lambrettas were never fitted with this feature

The flywheel may have sheared the woodruff key and have slipped.....in effect causing slipped timing.
