Can you explain more about the mixture, how much of each one would I need.
So some white / mineral spirit, Acetone (is that nail vanish remover?), ISo achohol, petrol, but what is NAPHTHA, never heard of that.
Thanks
Sure...acetone is a strong resin remover, petrol helps to keep the rpm's from dropping as much, NAPHTHA is another solvent similar to White Spirits only they vary in point of ignition and drying time.
The quantity, as I said regarding 2 parts and 1 part, depends.
I use 8oz or 1 cup as 1 part. So for spirits and NAPHTHA I use 2 cups and 1 cup each of the remaining liquids.
If you choose 4oz as 1 part...then you'd use 1 cup each of spirits and Naphtha, and 1/2 cup for each of the remaining liquids.
If NAPHTHA is unavailable there, you can simply double the quantity of spirits. However, you can also apply 100% spirits.
I only began messing around with a mixture because I get asked often "Why don't you use____?". I have found that there are some fuel system cleaner products that include those solutions...so I figured it can't hurt to try them. My last cleaning with this new mixture I didn't bore the valves, but I will after the next one. I may, myself, go back to applying 100% spirits as I have always done in the past. It will depend on the resulting bore-scope pics and how they compare to the 100% spirits pic.
