[QUOTE="kirkwilson, post: 10611, member: 625"] Well, I spent the day going over the carbs. I didn't separate the carbs or take off the linkage since 3 of them were running good. These carbs were definately recently rebuilt- They are spotless inside. The rubber looks new except the vacuum chamber sealing rings. The floats heights were all set exactly right. I pulled the float and float valve/spring off #1 and #2 to compare them- spring tension was at least as good on #1. I weighed the floats to see if #1 was heavy and it was exactly the same weight as #2. Do I need to replace the sealing rings? I don't know about some of the other stuff, though. All of the vacuum piston needles had various marks and scuffs- #1 and #3 were about 1/2 mm longer than the other side. #1 was the only one that had a sharp point- the others are kind of rounded off. Also, with the vacuum pistons out, looking down into the venturis (venturi's venturii- does anybody know the plural of 'venturi'?), the needle jet on #1 looked dull and/or dirty. The others were shiny. Anyway, all 4 piston needles had a lot of marks. Does this mean I need to replace them? And if I replace them, do I need the jets replaced too? Any other ideas why this one cylinder is fouling plugs are very welcome- Thanks! [/QUOTE]
