Thanks for all the replies…I have not had the time to do any more testing, but I think I’ll start by blowing out the idle circuit on the offending barrel.
I did say there was some residual
oil on the plug. It is NOT wet, but has a slight film on the electrode. I smelled both plugs that were recently in the cylinder and neither has an odor of gas. I really don’t think that plug was firing at all. The original plug I took out HAD been firing and looked to be fuel fouled (black and sooty).
The last drive I took in the late fall I remember the car running pretty well. The problems started with this first spring drive.
If the carb doesn’t fix it, I guess my next step is to run a compression test on that and a couple other cylinders.
If I have destroyed the rings in that cylinder, what are my options? Is it as simple as honing and replacing the rings with oversized, or is it a complete overhaul of the engine? I have just over 4300 total miles on the engine.
Thanks,
Gun Doc
