Typ 3,
I have been having some trouble with my engine that I suspect is related to
this strange spate of hot weather we have been experieH(r‰ here in the
insect-infested swamps of Northeastern Europe (Finland). For about the
last month, it has been between 25¡C and 32¡C, non-stop.
Anyway, the problem goes like this: the engine runs fine after the initial
start-up and still fine after I have been driving around for 30 minutes.
However, if I turn off the engine and then re-start say, 10 minutes later,
the idle is uneven, acceleration is piss-poor and it even feels like I am
not running on all cylinders. If I make a roadtrip (more than 75km), shut
down and restart, it is even worse and sometimes takes 5 seconds of
cranking to get the engine started. Fuel economy is about the same as
always - 9l/100km - and I have not noticed any other problems.
The engine is a basically stock 1584cc mill, with 34mm FRD carbs, Facet
electronic fuel pump, CR is 9.5:1, 009 distributor, Crane XR-700 optically
triggered points box and I use only 99 octane leaded fuel ($4.75 a gallon).
The engine has been driven 8.500 km since the total rebuild last August and
has otherwise performed flawlessly. I recently lubed and adjusted the
worthless hexbar linkage, adjusted the valves, cleaned the Crane eyeball in
the distributor, balanced the carbs and washed the windows.
Still the problem persists.
My only thought is that due to the heat, the fuel is vaporizing in the
carbs before it has a chance to enter the heads or while it is travelling
the short journey down the intake manifolds to the combustion chamber.
Obviously, if this is the problem, I will just have to wait for winter and
it will go away.
Has anyone from the heat-belt noticed any similar hot weather performance
problems?
Help.
