In twin HS4s on Barney (1293) running #6 needles, I tried 20W/50 motor oil, then Singer 3 in 1 oil. Both were too thick and it would go way rich just off idle (checked with A/F meter).
I'm now using Dexron III ATF fluid, and it's sweet.

| Post subject: | SU Dash Pot Oil |
What type do people use and how much? Im using some Singer oil and have put enough in my twins so that when the piston is fitted to the dashpot about 1/2 in from the thread i feel it contact the oil. I had tried auto trans fluid some time ago but really remember if there was any difference in throttle response? |

I also use singer sewing machine oil! I don't thing it would matter how much as long as it's more on the full side, than empty. |

My HIF 6 went lean on full throttle acceleration with ATF so now it's got HPR30 back in it and it is way better. (Dodgy Dick Smith O2 meter but better than nothing). |
