Solutions for too much compression
I've mentioned this some and gone further. I do NOT generally like nor do I depend (entirely) on "dial up" lights. Mark the balancer instead. Way back in the 70-89's I sold auto parts for about 15 years. Back in those days, there was a couple of repair services for things like instrumentation and timing lights and such. I got involved with as many as 4 or 5 timing lights that were simply not accurate or dependable
I still have my old Penske light I bought new back in the 70's, and recently bought it's twin at a garage sale a few years ago
