Re: 1983 C10 305 mind boggling engine problem
It is a 1983 305 engine with 2 barrel carburetor. The truck never goes over 20 miles per hour as it is a ranch vehicle. I started to notice a loss of power about a month ago and it would range from no problems to a severe bog down, requiring full throttle to climb slight inclines.
As of yesterday the problem is constant the engine will rev when in neutral but under a load it always bogs down. I checked all the spark plugs everyone one is wet fouled but sparking like the engine is running rich.
The water temperature runs around 225F constantly after the initial warm up period.
The air filer is clean.
The carb is clean with both jets functioning properly.
When I get back out to the ranch I am planning on cutting out the CC and replacing the 18" section with 2.5" flex tubing to see if this fixes the problem.
