Re: About to buy, nagging engine issue - seeking advice
It is my understanding that WD40 no longer has a flammable propellant and should not be used. In cold weather I hang a heat gun from the ladder and direct the heat towards the glow plugs and air intake, but not too close. Four or five minutes and 15 seconds on the glow plugs I have a quick start. 1981 Catalina 27.
