Ive recently rebuilt my engine
, changed the balance disc and lapped the valves and it runs great. Ive been using it to charge batteries
with a mechman high output alternator
which works great and will put out a nice charge at very low RPM
My question is about the start-up which is instant with a warm engine
or if its been run within ten or twelve hours. But on startup after sitting overnight, sometimes it can be fairly stubborn even though the boat
is kept above 50 degrees and I understand that a really cold engine can be very difficult to start. But it seems that the injection system is the culprit rather than engine temp. What seems to be happening is a bleed-down of injection pressure, so that the engine must crank for about 30 seconds to build enough pressure to start and then it tends to miss a bit, just at first on low throttle.
Im wondering if there is a check valve in the injection pump
that could have corrosion
or some impurity causing it to leak down.
Ive been considering an engine block heater
to assure that starting is easy and quick, but I suspect the reason for the harder starts is not attributable to temperature but rather a fuel
One for the experts.
Thanks everyone and happy Holidays!
