So now that I have my 1.7L with D-jet running I need to do some fine tuning. It's getting pretty cool here now and the last couple of times I have started the engine it has been around 45 deg F and I have to constantly maintain the throttle to keep the engine running. it does start right up though. Shouldn't something keep the rpms up with a rich mixture. I did a some looking on B. Anders D-jet site but didn't really find an answer. AAR? cold start inj? intake air temp sensor?

Hey Sean - keep us posted when you solve this one. My taildragger does the same darned thing with the heater lever. Odd I always thought. So I'll try the ground strap too.
When you solve it let us all know. You asked how to find which cyl might not be firing? Old aircraft trick was to put a smudge of lipstick (use the stick not the tool wench herself) on the cylinder fins - with engine cold. Fire it up for a few minutes only - the cylinders that are working will have melted smudge of the schtuff and the cold cyl will barely if at all smudge. Of course you'll have to craw under the car to apply this method - or maybe a rottiserie (sorry long day at work) The real A&P mechanics will chime in on this one for sure |
