I know I have a PK, and not many of you in this group have one, but the principal of this problem is probably relevant to most of you.
I have what appears to be a fuel starvation problem, but is confusing, because the scoot will work with the choke out. I had a guy look at it and he thought my problem was one of over heating due to too much oil in the petrol tank. He cleaned out the carb several times and had it running sweet. My petrol was low, so I filled up the tank with 5 litres of petrol. I then put in a 100ml bottle of 2 stroke oil which had sufficient for 5 litres at 2%. This is as far as I can tell correct. I got five miles down the road and the fuel starvation problem started again. I have had a look at the fuel pipe and think it may have been routing rather long and high. I took 10mm off the pipe and made sure there were no obstructions and refitted it. no joy
I took off the fuel tank and checked the fuel tap seal. this had some chunks scored out of it and loose rubber behind the fuel tap connector that may have been restricting some of the fuel.
I emptied the fuel into a can and noticed there was some rubber in the can. Therefore some rubber may be in the carb as well, but it works on the choke.
Question: Why if I appear to have fuel starvation, will it get me home on the choke?
All ideas are welcome, 'cos this is getting me down and running my whole enjoyment of having a scoot, especially with the wife nagging me about the ornament in the garage!!
