"Hi Guys, just had a problem with my DF 70 in that after an hr of running, if I shut it off and restart after 5-10 min's it cranks but will not fire. Recent work done is new inline fuel bulb...new water pump, fuel filter, oil changes etc, new spark plugs. If I lift the cover off for 10-20 mins and let it cool starts no prob???
Strange one, guidance would be greatly appreciated.

"My DF 115 is sometimes hard to start when hot. Always does, but sometimes takes 10-15 seconds of spinning to catch. If it's vapor lock, as you suggest JIT, what is the cure? How does vapor lock occur on DFI engines?"
