| Comments: | On the first test drive, fuel percolated in the carburetor.
This was solved by adding an spacer between intake manifold and carb mounting.
The original rear axle ratio wasn't so good - very short gears - so I ordered
a "V8" ring and pinion gear set which will be installed shortly.
I haven't had any problems yet.
Water and oil temperatures look well.
The engine is running very nicely! |
