I’ve transferred the various carb shots to paper (in colour) and will keep them at hand when re-assembly begins.
Although not showing I screwed the carb to a wood block so that I could use a vice to keep it steady while I removed parts. Surprisingly most of the screws came off without a hitch.
More carb shots. Better close up of the spring positioning.
For the most part this carb had all the usual circuits albeit slightly different – especially the complex choke linkage. One other item is the thingy sticking up in the photo. It is the factory metering adjustment screw. It controls just how far the primary needles drop into the main jets and is set at it’s optimum position at the factory. I really didn’t want to remove it, but it sits in a well with a tension spring below and it might not be easy to clear that area of cleaning fluids. The photo shows the adjustment screw just about out of it’s well . Before I loosened it I took a careful measurement and found it was about .026 thousands above the carb deck surrounding it. When I put it back I”ll try and get it back to the factory setting.
Time to get the major crud from all the nooks and crannys.
Basic cleaning done. Some parts will be cleaned up using Simple Green and others will be sand blasted and painted.
I do enjoy rebuilding carbs 🙂
