I just about have this little truck sorted out. My oil leaks were at the fuel pump and valve cover. Was also leaking coolant from around the thermostat gasket. Of course, in the process of fixing this leak, one of the bolts broke off in housing. Ended up drilling it out oversize and tapping for a new bolt. One more problem solved. Last issue is that the truck seems like its running on 3 cylinders when the motor is cold. Once warmed up, it runs fine. The choke looks to be working correctly. Any other suggestions to get it running better when first starting?
