Interesting, because I have done just that and it seems to have done the trick with my autochoke problems!ellevie wrote:This appears to be from the same source as the pdf link above.
The interesting thing is that it seems to suggest that a sticky choke can be cured by lubricating the waxstat drive rod with a few drops of oil. Might be worth a trying and comparing the before and after required times for the choke flap to reach the full vertical position.
I took off the body/vacuum chamber and doused the linkages underneath with a liberal helping of WD40 - then I noticed a bit in the Haynes that says to grab the drive rod with pliers and push it into the deflooding capsule as far as possible, then measure the strangler flap opening. By doing this I finally discovered the mechanics of the pull-down system, and also determined that the rod was slightly sticking! As I didn't have much time, I applied more WD and moved the rod in and out several times (I plan to apply a few drops of 3-in-1). But just with this simple fix, the cold starting has improved dramatically and the engine doesn't die suddenly as it was apt to do, even if I held 2000 revs). Hurrah!
