KB4040 not running properly
Hi, we have a KB4040 which has suddenly started playing up. One minute it was OK then it started to run a bit like a car running out of fuel. It will start to fade then vroom and then fade. 20 or 30 seconds later it would do it again and the time inbetween got shorter and shorter and now it is doing it all the time. Looking online a forum (Tyresmoke) suggests the cylinder head is cracked. Would this be your thoughts, also? Would (stock No 538427) solve this problem or would I need other parts? The pump hasn't been dismantled yet. Many thanks
