Ahhhh. So nice to have the GRUMP back stirring the pot here.....
CHARLIE - Can We update the FAQ about the hydro relief valves to add DON T's info about which one is for forward & reverse?
JEFF - There's been many CC's put under loaders with 7, 8, & 10 HP engines, a 12 HP as long as it's running right should run a hydro tractor plus the OEM lift.
TIM D. & Gregory - MMO won't hurt anything but I really doubt it will magically FIX your problem. More information like is the engine only idling for 15 min, or pulling HARD, any unusual noises when it stops, etc. would help US help YOU. Of course the info given already like looking for broken wires, bad grounds, coils, plugs, condensor, switches, etc. is important too. Engines need THREE things to run, well, maybe four. Fuel, Air, Compression, and Spark, and all in the correct amounts and times. An engine that runs O-K then dies has something interferring with ONE of those things.
LUCAS - If there's just a little oil residue, you may be able to just re-torque the head and get it to stop leaking. I did that several times over the course of 1400 operating hours during the 20-21 yrs I ran the K241 in my 72. The engine would "WHISTLE" at me when doing a cold start, then as it warmed up would stop whistling.
