Hi,
Went to rescue a TO-30 I had loaned out and
no start. No spark. Points looked awful.
New points and condenser and it starts and
runs fine for about a minute and dies. 6
volt z129.
However it dies strangely. It runs on what
sounds like.one cylinder and dense brown
black smoke pours out of the stack. Stop
the engine and it starts right up firing on
all four cylinders again, for a minute.
Then it misses again.
The coil and wires are recent. The spark.is
1/4 inch and white. The fuel flow is
present but not gushing. I pulled the carbs
and did a quick teardown, all was ok. I had
rebuilt the carb about 2 years ago.
The fuel filter in the carb is fine and I
replaced the sediment bowl screen. I can
drain the tank and clean the in-tank filter
tomorrow... But
I am.mystified. got spark. I suppose I
could check.each plug and wire one by one
but all four fire when it starts. I was
thinking it was unlikely that it could be
fuel making it miss. Changing choke or
throttle.makes no.dofference.
Advice appreciated!
Thank you.
