post only, restore my zr-1

[zr-1.R1]

first of all I apologize for my bad English by google translate.

peaks is my first series 1990, 59,000 km and two owners, was stopped three years.
the first thing I changed the spark plugs, they were wrong, changed the oil, checked that the vacuum pump would work and that the system vacuum was ok.
now the car is better, but at least occasionally miss a beat.
also in acceleration is not very bad.
the first thing I ordered the inettori overhauled to SFI guaranteed three years now I wanted to ask before installing them, the plastic plugs SFI told me not to remove them, is that right?
I will stop for now, later on other questions, thanks
