A week or so ago, I restarted the engine on my S3 Coupe, which I hadn't yet used this year and had possible left it standing in my garage a slightly unacceptable length of time. At first it showed no oil pressure which worried me a lot but a blip up to higher revs freed it up to normal pressure. I then topped up the oil & put coolant back from the overflow bottle back into the system. Yeah, I KNOW I should have done that first...
That oil gauge behavior was still a bit worrying so last weekend I took the cam cover off and then each cam cap in turn to check for oil. I put in a squirt of extra oil on each before putting each cap back on. Taking the top off ruined the cork gasket and I had no spare so I have used a layer of blue Hylomar on naked alloy. It doesn't leak, but I expect it will be a problem getting it unstuck next time.
On Friday, I took her out for a spin/test-drive and when I'd done about 8 miles while waiting at traffic lights in Potter's Bar the Idle Speed dropped down & she stalled. It was difficult to get the engine going again (why do stupid people behind you blow their hooters when it is clear that you are doing all you can to get going again). I eventually managed to get around the corner to a quiet spot and had to crank up the idle speed to about 1600 RPM to stop her stalling. So I went home like that having to use lots of low gears and clutch because 1600 RPM drive speed was too fast for the traffic jams.
Anyway Thursday was a busy day cleaning all the Dellorto jets and passageways and I found on taking the tops off that there was no fuel in the rear carburettor's bowl, so it seems that the float valve must have stuck shut causing my problem. A quick jiggle and a squirt of carb cleaner seems to have fixed that. On the idle-jets and Idle Bypass screws I counted the turns down until it stopped and wrote them down so after cleaning & blowing through, I screwed each right down then back up by its noted number of turns. This process seems to have set the mixtures etc back as they were last year though I might dig out my see-through spark-plug and balancing meter sometime soon to double check that.
Anyway, I'm now glad to report that all seems OK and she idles well at 800-900 RPM and I did a quick visit to Ye Olde Lotus Factory in Cheshunt as a test run on Friday.
