I need some help. My trusty 1956 420S is hard starting and now won"t start. Cleaned carb twice with no luck. Front plug looks good, back it is all black including the white insulator. I only have 6 hours on these plugs.
It started about 3 months ago where it would run normal for 30-45 minutes and then seem to be robbing of fuel. I could pull the choke and it would recover most of the time. Now I can"t even get it to fire unless my son pulls me with the SUV and I bump start it.
Also when I crank and crank with the choke on then check the
Plugs they are dry. Can"t figure this one out and I have a bunch of mowing to do.
Any help much appreciated
