I bought a project 7 few months ago. It was used used last 10 years around 50 miles/year (MOT round trip ) It runned roughly so I started to work on carbs, balance, ignition etc.. I found advance at 20° at idle and 45° à 4000rpm (As far I know values are aroud 10° at idle and 35° at 4000°)...and discover a sized disbributor (both adjusting screw well removed and alot of WD40 sprayed) How can I do ? I will remove carbs for better acces .. but it is round and fragile Any help welcome
