This video helped me lots. The engine sounded like it wanted to tear itself apart at higher RPMs. Took the cover off and i immediately noticed the points were 2-3 times further apart than they should have been. Took 5 sticky notes and then backed it off about 1/16th of a turn and now she runs smooth. Now I have to deal with the unknown oil leak.
Check the oil filter mount for the oil leak, I have a video for that as well.
By the way good video easy to understand
Thanks for the vid. I have a case 446 with the B43M. The engine starts to run rough and die after 20-30 minutes. Once cool, it is ok again. Any ideas of the cause? Also, are any of these after market parts ok to use? Any links to parts source? Thanks in Advance!
It could be a coil going bad that acts up once it gets hot. I wouldn’t go buying the cheapest parts out there though, I tend to look at the reviews of things to see if the quality is decent.
I'm not getting any Spark all the sudden never not started in 30 years took it off trailer couple weeks ago put it on and maintainer which I always do. Went out to start it no spark. No spark plugs no spark at points but I'm getting 13 volts through to the points. Any suggestions. Thank you in advance
Are the points actually moving when you crank the engine?
How come you replaced? Ours is surging with a new carb and people suggest replacing
Points and Condenser should be replaced periodically as part of normal maintenance. Your surging is is likely something else, such as a carburetor issue or intake manifold vacuum leak.
Help! I’m a little confused on the wiring for the coil. Does the condenser go on the positive or negative? What exactly is connected to the pos and neg side of the coil?
Condenser goes on the positive side of the coil. Going by the drawing, orange wire is also on the positive side and black wire is on the negative. It’s a good idea to label things before taking them apart to keep from getting mixed up.
Great video however I disagree with your answer above. The B43 motor has the condenser under the points cover and connects to the points, and the points wire goes to the NEGATIVE on the coil. The POSITIVE on the coil goes to the Time Delay Control Module. I think you were confusing the B43 motor with the P218 motor with electronic ignition.
@@bigragu98 I think you are correct, I may have looked at the P218 wiring diagram by mistake. Good catch.
Hey, looking good. If got a question. It easy to change the oilfilter? Mine has got a hole in it... thx best regards roli
What makes you think it has a hole in it?
Well oil is dripping out of the oilfilter. The frontside of the filter has worn down from rubbing against the chassis
By the way, what oilfilter do you use for the performer 20?
@@rolika5520 I’ve always been able to get mine off with a small oil filter wrench without an issue. If you get it off and there isn’t really a hole in it, the leak could be at the adapter plate. See my video on that here: ua-cam.com/video/VbPJ4d5yFiE/v-deo.html
@@rolika5520 NAPA 1374 will work I believe, though I’ve never had this engine to know for sure.
I have a JD 318 back firing through carb idles ok but won't take any throttle could points be my problem
Possibly, it’s definitely worth replacing them or at least checking them to make sure the gap is correct.
How were you able to tell the points are bad my 318 once it’s warmed up an under a load is starts missing and backfiring thanks
Mine weren’t necessarily bad, I replaced them more as a preventative maintenance item. They’re cheap so it can’t hurt to try that. Your issue may be coil related also.
My 1990 318 is doing the same. I've changed fuel filter, fuel pump and fuel lines and still does it. Am considering points and condensor next. Have you resolved yours?
I see a cover with two bolts
Lo mismo yo sstoy confundido con el cableado de la bobina un comentario positivo porfabor
I don’t see these points on my 318
What year is your 318? Later 318s didn’t have an Onan B43G, but instead had a P218 which doesn’t have points.
