Some things you might look at after you have checked all the stuff that Steve said to look at is the drive and driven gears and the pin that holds the drive gear to the govr shaft if the pin is gone or gears are wore a lot and without the points holding some drag on the distributor and now you installed the pointless unit there's no drag on the distributor shaft and that will make the timing move ahead and back some.I'd put all the old stuff back on the tractor check the timing and see if it's still moving ahead and back like it did when the Pertronix kit was on it.

Well it was operator induced error.
When I took the valve cover off to verify that all the rods where in place I turned the nuts a little tighter. This compounded a low compression issue with the valves. I found this out by starting over going over the steps I had done. When using my finger to find TDC on #1 I noticed that I had very little air coming by. I put the gauge on it and it only had 20 lbs or less. I reset the valve clearance and now I am at 205 compression on all 4 cylinders. Starts right up and sounds great. I learned you can't slap it back together and not check the tappet clearance. |

Good thing you didn't bend any push rods!
Surprising when you back track and find your OOPS... |

Interesting subject. I have a MF 175 with perkins 4cyl gas engine.
My plugs were fouling so I put in a Petronix ignition. Still had plugs that would foul. So I switched to premium gas with no ethanol, and now my plugs do not foul. This might help you out. |

Try switching to premium gas with no ethanol.
It helped my MF 175 perkins. Plugs do not foul now. |

I suspect that the ethanol mix fuel burns a little cooler. A slightly hotter plug might accomplish the same thing.

Ah... actually now, the best lesson, is to identify everything you changed, before troubleshooting a problem. We didn't know you'd changed anything in the valvetrain... had we, I'm certain we would have had you go back and check those FIRST. Glad you got it figured out. class dismissed, time to go out and play! ![]() |

I didn't think that would have affected things but then I remembered on here someone posted having that valve train issue.
My Bad!

I would also check compression on cylinders to make sure
You don't have a problem there. 2nd reply on January 5th. |

Yep! I was stuck on the electrical issue and it ran OK prior to swapping out the points. I never had a low compression issue before and didn't know how it affected the engine. Live and learn! I can now click that box. Full history: I put in new sleeves and pistons. Got it together. Tractor started and ran, Good Oil pressure. Turned it off. Put in Pertronix and it ran like crap. Ask forum for help Took off valve cover to check that rods were in fact all in since piston number 1 plug was wet. Yep, looked good, checked nuts again on valve train as the oil splash thing I couldn't remember if it had a washer or not on the nut.. Messed with Pertronix to ensure it was in correctly. Ask forum for help Checked for TDC on #1 and had very little pressure. Freaked out. Compression gauge test and came out real low. Freaked out again OK, I remember online someone commented that torquing the rocker nuts down caused a compression issue. Yep, the valves were tight. Adjusted per book and wham pressure is up to 205 to 210 on all 4. Slapped myself silly. ![]() |

Being a service manager for 18 years I learned the guy runnin the machine can usually tell ya how to fix it, but ya gotta ask a lot of questions and sometimes ya gotta talk to the operator more than one time. Stories change, people forget things, can get off on one issue and forget what the big picture was. Glad ya got it fixed!!
