Roxy: Idle Problem Fixed! (sort of)

Hallelujah, she runs!  But I cheated a bit in that I just swapped out the carb with Viola's carb (labeled CS90C), which I'd already cleaned.  She started up and ran like butter.  Actually had a better, lower purring sound than with the old carb for some reason.  Idled strong for 5 minutes with no signs of hesitation, and it was a warm day so I think the running rich issue is gone.

I suppose I'd still like to figure out what's wrong with the newer carb, but first I'll have to figure out how to remove the stuck float pin.


First thing I did since the engine was cold was to check valve clearances.  Happy to see they were .002" on both intake and exhaust.  Also learned from the forum that the reason the PO probably added the breather tube was to accommodate a bigger cylinder or higher RPM.  Since there's a piston in the old parts bin from the PO, I wonder if the cylinder has been bored out.  We'll find out eventually.

Beautifully clean alternator compared to Viola's.

Then did a compression test for the first time.  Again, thrilled to see that I was getting 120 on a cold engine, especially since I was worried about an oil leak into the cylinder.  Odometer at 17,571.

Noticed there was this hole in the bottom of the muffler, though it seemed like someone put it there on purpose.  Another PO mod to increase breathing?

Also took the opportunity to switch to the new shorter filter (Visu-Filter Mini) that came in the mail today.  Much easier to squeeze between carb and petcock, and doesn't kink the line.

And finally everything installed.  Whew.  She idled and revved smoothly, but I'll have to take her on the road to really make sure everything's sorted.
