Do a search on Google for “Massey Ferguson Intake Heater” for about $20 you can buy one, you need to hook up a line for fuel ans a 12v switched wire for power, but it does work once you put a threaded port in the intake manifold.
I am new to this Forum so although it has been awhile since last post in this I decided to let you know about this.
This actually starts a small fire inside of your intake. Turn on the heater, it will automatically let the fuel in when it gets warm enough to ignite, about 20-25 seconds, sometime you actually hear it lite, start cranking the engine, and it starts.
I hope this works for you, but have to install a threaded port in your intake.
