Hi peeps, you may remember me from such times as "how come my engine
wont start" and similar fun.... this time the engine
[Universal 5432] is running. In fact it's running pretty well all told, start's, moves the boat, hasn't really worried me in the last, umm, well since last time it worried me....
Anyway, this last week the idle started getting a bit inconsistent. By this I mean that it will run at what we set it too, say 1000 rpm
, then, for a period of several seconds drop to a lower rpm
, perhaps 100 rpm lower in this case.
Shortly thereafter it'll return to it's normal setting and run there for perhaps another 30 seconds or a minute, before repeating.
Initially this seemed to happen right after startup then stop but when returning to our slip last night it was happening while cooling
down after running at 2300 for about an hour.
So far guesses include dirty injectors or some other flow problem in the fuel
system, probably nearer the engine than earlier in the fuel
What do you guys think?
