HS2 carburettor. To what level should I fill the dashpot with oil and what sort of oil should I use?

Top up to the top of the narrow section of the dashpot - you will see where it narrows looking in after unscrewing and removing the piston damper. SU make oil for this but ordinary engine oil or 3-in-1 will do the job.

Thanks very much for your quick response. I'll use some engine oil.

To test if you have enough oil in the dashpot then unscrew the plunger and try to pull it out a little bit and then push it in again. If there is resistance then the oil level is fine.
