Miss and carb tuning troubleshooting

compression test? leak down test? plug reading?
I like the spacer idea. I like the carb kit, because the needle and seat may be leaking, especially when hot. Immediately after hot shut down, look down the primaries. Do you see any wisps of smoke rising up, or a fog of vaporized fuel. That usually means worn needle and seat, and/or too high float level.

Compression test is due this weekend and will probably tell me a lot haha. Will probably get a leakdown test kit when I am at the parts store too as I have been meaning to get one for a long while and have a compressor now. Plugs, last time I checked had black carbon around the ring, spanned down about 2 threads, porcelain was somewhat white with light black tinge from what I remember, no idea as of now, but same symptoms then. I'll pull the filter off and check out for smoke when I get home from work while its hot and report back. Thanks!

P.S. Working on cars at an apartment with no lighting in the dark sucks, needa find a new place with a garage!
