Common problem with points, or if not used very often - either the points get pitted/burned or the rubbing block wears down, which changes both the dwell and the timing.
This doesn't usually cause the idle increase however, that is more likely a vacuum problem. | | | | | Joined: Apr 2009 Posts: 192 Shop Shark | | Shop Shark Joined: Apr 2009 Posts: 192 | yes, running points still.I am leaning towards a carb. issue.Thanks and I'll post the results. | | | | | Joined: Apr 2009 Posts: 192 Shop Shark | | Shop Shark Joined: Apr 2009 Posts: 192 | Carb. needs to be rebuilt,that's the mechanic's conclusion. | | |
