17 Apr 19 Cold Start Enrichment

After a pleasant meal out with colleagues I returned to my chalet (I’m working away at present) and got the carbs out on the table to do some more work on the cold start enrichment mechanism on the rear carb, which I will call the choke from now onwards. Despite some earlier efforts to clean this up, the mechanism was still so stiff that the return spring couldn’t well, return it.

So I stripped it down again and sanded the surfaces with some 1200 grade sand-paper. On reassembling it still wasn’t very free, so I took it apart and used some 800 grade sand-paper and concentrated on what appeared to be some corrosion within the body of the carb which I think was causing the friction. The frustration is that when loosely inserted it moves freely and only tightens up when fully assembled. Sigh. End result, moving better, but still not enough, so another strip down and sand is due, but not tonight because I don’t want to be doing this all night!

On the plus side, I am cleaning more bits as I strip them and I am getting to know how it all fits together, which can only be a good thing for the future.

Best wishes all.
