I’ve never used it personally, but have heard others say it has helped them with rough idle. I believe there are good instructions, i.e., use a third in the gas tank, a third in the crank case and a third should be sucked in through a vacuum port. I would make sure it goes directly into the manifold as it could be not-so-good on a check valve. That said, this may not provide a strong enough concentration in the gas to address any carburetor internal issues, and I’d be tempted to use the entire can in the gas tank.

It’s made up of Pale Oil (petroleum) , Naphtha and Isopropyl Alcohol so it will burn like a banshee but make sure you run it through fairly quick and don’t let it sit in your fuel system. Maybe add it and go for a nice long

Years ago we used a similar product made by Rislone and it worked pretty well – but it does smoke like there’s no tomorrow when you suck it into the manifold. If you decide to ingest some into the intake, you may want someone to hold your RPM at about 2,000 to make sure the engine doesn’t stall. Do it at night or you may have the DEQ or the cops at your door - and for heavens sake, don't do this in a garage, rather out in the open.

Let us know,
