i think i may have cracked it from a thread i read a few months ago they said to cheak if there are any leaks on the carb and through to the engine by spraying some carb cleaner near it when this was done i heard a change in tempo so sprayed a fair amount and it runs ok and throttles up ok so i assume there must be a leak ?
i have taken apart the carb and extra plastic bit off the side of the engine but cant see any real holes or ways but now asking the question can i make my own gadgets for a temp measure to cheak if this is the right problem i do have make your own gadget paper but not the right gauge would this do just to cheak ?
thanks for the help i have added a few pic smoe of the pic are not that great
