not sure if i'm just getting used to the mysteries of a manual choke and a carb or if there's actually a problem. anyway, my truck starts right up in the morning or after it's been left for a few hours. also starts right up if it's been running to normal operating temp, turned off, then started again a few minute later. however, if it's been left for 10 minutes to about 2 hours it doesn't want to start right away. it turns a number of times, eventually catching and then running pretty rough for a while. eventually runs fine, but it takes a bit. could this just mean adjustment of the carb? or is it more. i know i have a warped exhaust manifold, i'm considering replacing that anyway, but i've also heard that a new one will probably just warp as well. but i do wonder if there's an issue with the intake manifold too. obviously, there a million things that could cause this on one of these, but i was hoping perhaps someone else has a similar experience that they could point me in the right direction. any thoughts would be much appreciated. thanks much.
