Re: Vapor Canister for '90 YJ
Aloha Mike and thanks to all of you for the info. Well did some more
checking today. I didn't find any sign of cracks or leaks in the suction
side unless its on top of the tank which I can't see.The short hose on
the return side of the filter did have some cracks which may have gone
all the way through which I will change tomorrow. The gas filter is
mounted correctly due to one of your posts a long time ago. Here are
some interesting observations. Looking in the top of the carb, it seems
there is plenty of gas when you are cranking in the hard start mode.
Certainly the bowl is full as evidenced by the fact that fuel will
squirt in normally while the cranking is going on. Also a strong gas
smell from the carb area. Nothing visible however. For this reason ,
maybe the problem is not with the fuel supply, although I guess that is
a very common problem.
Is it possible that the problem could be something in the ignition.
Maybe a coil going bad when it heat soaks and doesn't make enough spark.
This would seem to explain why it seems to be flooded when it finally
does start and why it takes so long to start.
It really runs good with no hesitation or other funnies once it starts
though, but when its running the battery voltage is up also. Anyway,
just grasping at straws here. I gotta get this fixed soon though. I was
going to try to look at the spark in the hard start mode, but I need my
wife back from Hula class to do that. If its still good, that should put
the ignition thing to bed.
Aloha

Re: Vapor Canister for '90 YJ
How is the distributor cap and rotor? Mine eats them up. They get a
bit of dirt or dust in them and arc out easy.
