With the 2L engine in my 107, it demands a clean carb and fairly accurate
timing to start easily. If the truck sits for awhile, which it has been
doing lately, I=B9ll have to clean the jets out to ensure there is no
obstruction. I find that the timing needs to be checked often. I generall=
y
just time it statically and the results are pretty good. The times I have
dynamically timed the engine didn=B9t seem to yield better performance.
I=B9d take the jets out and clean them at the very least. Also, maybe you
gravity feed fuel into the carb instead of pouring it in. My engine seems
to be a little finicky with flooding at times. May be you have experienced
the same problem? I=B9ve heard of Series Ones changing ownership and the
truck coming with a Jerry can fitted with a petcock and hose fitting so the
canister can be mounted on the roof and feed fuel if the pump fails. Gets
you home...
Good luck.
