Mercury/Quicksilver Parts 858080K01 POWER TUNE @1 POWER TUNE ENGINE CLEANER

I bought this to clean the crab on an old Suzuki VL800 which had been running rougher for a year and finally wouldn't run or idle without the choke on. I ran the carb dry and ran this cleaner in through the fuel line, then let it soak for twenty four hours. The next day I started it up and it was running like new. It saved me a crab removal and tear down. For any engine that sits for longer periods sometimes this cleaner could make a big difference. Delivery was also quick, arriving in the mail.

Follow the directions on the can, it works on all size engines.

really does the job,

This is more $$ than most carb cleaners, but the difference is not bad when you want a cleaner that gets the job done. I have used both kinds , and have gone to using nothing but Power Tune and never have regretted it. It will often get the motor running without taking the carb apart , nor off the motor.

Works great to help cleanup the build up inside an old boat engine.

Excellent product. Last resort before ripping motorcycle carb apart. Worked great. Bike runs like new.

Had two cylinders in Yamaha ski that were down about 50psi from sticking valves. Filled the cylinders up with this, turned the motor over with coils inplugged and was able to push the valves closed enough to get compression to get a motor that was sitting for awhile to fire up.

I don't know about giving my 4.3 LX more power but I really like to keep things clean inside and out. Be sure to bring the the motor up to full operating temp before using power tune and I do the PT before I change out to new spark plugs.
