I have had another curious problem with a couple of PT's in the last few months. Both kerbside pick ups so no big deal but what has me stumped with them is after fitting my test carby they both fired up and ran for several seconds and stopped. I haven't been able to get another peep out of them and all points to them having been straight fueled as I get zero response with the starter fluid. What I don't get is why they ran for a couple of seconds. I might pull one down and see what the bore looks like and if not too bad give it a hone, new set of rings and see what happens unless anybody has any other ideas
