Plug's and Jets..

100 miles into running in an new barrel and piston in the Vespa and it's time to check the plug....running a little rich for me so may need to adjust the main jet in the carb...will keep it rich for now while running it in...

The joys of 1960's 2 stroke design principles toay...have you ever had to measure 2 stroke oil and add to your petrol to ensure your engine's run on a 3% mix ???...it's all about the style
