Cub won't start
Posted: Mon Apr 22, 2013 3:38 pm
Hello,
I'm a new member on the forum.
I have a 48 Cub that belonged to my Grandfather, I've had since his passing in 1989.
It has always been very reliable, and I have been able to fix anything that came up until now.
I was plowing snow in March, and it just quit like the switch was cut off, after working on it for a couple hours it started but ran poorly, I tried to get it back to building but it died, and I towed it in.
I have cleaned sediment bowl, replaced in line filter, put new kit in carb.
Pulled plugs, checked compression (it's low , but when cranking there is good suction at carb)
I have cleaned points and checked gap (it's a magneto)
Many times I have pulled a plug and grounded, it has spark, also if I pull coil wire it has spark.
Sometimes it will "put" once or twice, and occasionally will run for maybe 10 seconds.
I have read that I can put a coil on and rewire the magneto to basically make it a "points" system, and I think that will be my next thing to try.
I'm operating on the idea now that something is wrong with either the magneto coil or the magneto itself.
I'm getting tired of chasing this problem,and need to mow grass.
Any thoughts ?
Thank you !
