Got a break in the weather so I got to test for manifold leaks.
That doesn't seem to be it, atleast there was no change in attitude when spraying WD40 all over the joints.
Just to be sure, new Champions installed with no change.
I managed to find some #78 bits to try to clean out the pilot jets, but I think it's going to be an interesting puzzle to find something to hold a bit that size. Haven't attempted that yet.
There are a couple more clues though.
The problem is definitely in the closed to part throttle range.
Also, an instant read thermometer touched on the head pipes shows the suspect cylinder to be running cooler (not cold) during warm up idle, 50 degrees to start but 75 to 100 degrees as the engine warms. There's a slight yellowing on the top of the suspect side headpipe now too.
Old Clunker, heh?
I resemble that remark and there are some parts that have worn in a bit.
