My Spirit runs extremeley rich on cold stat for the first 2 or 3 minutes after start up (engine"beats" and exhaust smells fuel) . I assume this is a problem with the choke solenoid / thermal time switch ? How quickly should this switch off andis it adjustable. Choke comes open via stove pipes quickly and runs fine after initial few minutes. Mark | ||

Hi Mark, My T2 also had this problem. I disconnected the thermal delay to confirm, and after that replaced it with a salvage part (from Paul Yorke). I took the old switch apart, and it's a pretty simple bimetal spring heated by a coil. So unless the coil has shorted out, it should in theory be somewhat adjustable (by bending the bimetal spring). But I haven't yet spent the time to figure out exactly what was wrong with mine, or whether or not it was repairable. The timing (2 or 3 minutes) is about what I was experiencing. That might be correct at -10 or -20C, but I was getting it at -2C, where I suspect it should be more like 10 or 20 seconds. Jeff. | ||

I have a feeling that there is an adjusting screw hidden under a blob of paint. | ||

Thanks gents, disconnecting the solenoid has cured the problem. Where is the timer located, so that I can have a go at it ? Mark | ||

Timer is on the bulkhead/firewall. Driver's side (for RHD cars at least), below the fan-to-evaporator ducting. It's a round thing about 2" in diameter and about 3/4" tall. |
