Redex
Anyone one remember the upper cylinder lubricant?
Had a mini countryman that after about an hour thrashing her would slow to around 50 mph. Stop at the side of the road, open the bonnet, take off the air filter and give a long squirt into the carb.
Closed everything up, jumped back in and opened her up.
Immediately would attain the dizzy heights of 70+ mph but would leave a smoke screen behind!
Looked in my rear view mirror one day to find the Waggon and horses had disappeared!
