Restarting the 1961 Volvo 210 Duet 

That guy squirting the starting fluid has a real technique. Good hand /eye coordination. I think he's done that a few times before. That double SU set up on a 4 cylinder reminds me of my old Spitfire.

Remove the rubber pipe and block off the nipple on the inlet manifold. The inlet on the oil filler cap is just that, an inlet for fresh air, normally from a spigot on the big blue Volvo air filters. The pipe as it is now is just killing the vacuum. This pipe would normally be used going across the valve cover to the spigot on the ventilation ear on the other side. There would be a valve fitted just above the side ear. This is all in the manuals. At this point just solve you start problems by clamping off the hose or putting a big bolt in the end. Looking forward to seeing it in the UK.

Will you be able to film it driving?
