most likely removed cold start systems. read through the factory service manual and do some searches, there are several valves and solenoids.

well, it started when the weather changed, so at first i chalked it up to cold starting. It wasn't jumping up to the 3krpm when starting for the safe warm up, i assumed that was the wax idle valve needing to be cleaned. then it started acting as if it were flooded every time i went to start it, even if it had just been running. So i would use the deflooding tactics, holding the gas down, or pulling the fuse. I kinda got used to that and was assuming it was an injector issue or something fuel related. As a few weeks went by with dealing with that issue it hesitated more and more each time i tried to start it. Then eventually it consistently would white smoke a little bit when it would finally start, again i assumed it was just too much fuel causing the white smoke.

Then eventually almost everyday my low coolant sensor was buzzing at me. Then finally it came to a point with all of the above issues happening each time i started it, combined with a strong burning coolant smell. Finally i decided it was time to have it looked at, and sure enough it was a blown internal coolant seal on the rear rotor. During all of this, and even up until the day i finally decided to pull the motor and start work on a TII swap (which is in the process right now) it would always run like a champ once it finally started.
