has anyone used valve seals on these 2 cylinder engines, if so were did you get them ? Thanks

I too am in Northern Ont, and curious as to were you may be, I am just east of Soo

My 40c will do the same thing in very cold weather as it seems it is easier for the pump to suck through the seal than from the cold hydraulic oil, I just let it sit and idle for a period of time before I use it and seems to help, Doesnt do it in summer time, maybe your screen is plugged on suction ...

if you are at all mechanically inclinated, you should take the inspection plug out and look in the hole with a good light, compare what is happening in the one that doesnt steer with the one that does steer, probably an adjustment needed??

changed coil and condenser and it runs as it should again. thanks for all the input

Thanks for the feedback, will order up some parts and will post back with what I come up with that fixes it

starts and runs properly when cold, after working(plowing and discing) for approx 1/2 hr, begins to misfire and eventually stops and wont start till cools down for overnight, has plenty of gas running out the carb drain when opened, has spark but very weak, what would you think might be the cause, t...

OK thanks for the info

I understand the problem with putting 12v on a 6 volt coil, but dont understand why a resister is needed if the coil is rated at 12v and the battery is 12v, How hot would an internally resisted coil get with a 24watt resister inside the can?

I am about to learn something. So if you need a resistor with a 12v coil used on 12v system, what is the voltage required on the 12v coil and what is the wattage of the resister that is needed?

if it is now 12volt, just buy a 12volt coil, no need for any resistors, now if you use a 6 volt coil on 12 volts , then you need a resistor

there should be an indent in the starter that the tapered set screw goes into holding starter firm, could it be wrong setscrew or not aligned with the indent??

I use my '53 40c every winter for last 20 yrs to winch out maple logs, I have a homebuilt wheeled logging arch and a pto driven winch, Front blade, I have had very little problems and use cornhead grease in rollers, Keeping in touch with what is going on with your machine will keep it running well f...

If you are going to try to reuse the pump and bearing I have put the whole assembly in a pail of grease then heated it up till grease melts, it will run into bearing to some degree and lube it, Works for me on some things, just an idea

I also have a 56 420 and to eliminate the moisture problem I went with a 180 thermostat and a jute bag over the rad for winter operation, they should be run at the top of the temp range to eliminate the condensation in my opinion
