I'm not exactly sure on how it was running before hand, I limped it home with a worn out timing chain so it was a bugger to get it going to do anything, as soon as you would touch the accelerator it would try to die,I thought it was the carb. so I had that rebuilt, put it on and then it would not start, so then the timing chain was changed, I did put in a new thurmostat on today but it is still running hot and there was still pressure on the top hose, I will re-time it to see what that dose.
