Quicksilver Power Tune. Is it 'snake oil' or does it do some good? The instructions seem very off putting.
Run 2/3rds of contents into carb throat (?? I've got four of them, do I need four cans?) while engine running at 1200 rpm. Increase speed to 2000rpm and stall the engine with the rest of the stuff
. After a bit start and run at 5000rpm for 5 mins. Will that be the end of my engine? What is this stuff? Will my engine get addicted, like a diesel to Easy Start?
I wondered if it might fix the odd missfire and spit back on tickover or fast idle, which I thought might be caused by carbon buildup or a sticky valve. Engine's 8 years old and not been heavily used. Any thoughts? Anyone with experience of the stuff?
I'm conscious that Quicksilver are Mercury, and Mercury want to sell more engines.
