A. At present we do not know of anyone
producing the LI decals. If these are being made, kindly advise our

21/3/22 Q. Herman Sass, 20 East Morris
Avenue, Buffalo, NY 14214 is looking for information on a Do-It-All
tractor built between 1917 and 1925 try Buffalo-Pitts Company. This
was a single-cylinder, two-wheel garden tractor.
21/3/23 Q. Fred Burkhart jr., RR 3, Box 136,
Robstoum, TX 78380 inquires as tothe age and proper color for a
GT-25 Terratrac tractor built by American Tractor Corp.,
A Our information indicates the GT-25 to have
been built about 1950 or 1951. It was powered we believe by a
Continental F-124 engine. The slightly larger GT-30 was tested at
Nebraska in 1952 under No. 471. Subsequently, American offered
several different models. J. I. Case purchased American in 1957,
giving them their start in the crawler tractor business. We believe
the Terratrac models were finished in an industrial yellow.
21/3/24 Q. We need information on an Ottawa
drag saw engine. It has two push rods. The piston is 3 inches in
diameter. What is the proper color, and what is the year? Also need
help in getting the engine back in time. Carl L. Hatch, RD 4, Box
277, Towanda, PA 18848.
A. Ottawa engines were a deep red color so far
as we now. Our supply of literature fails to show the model using
the 3' bore however, but we would guess your engine to have
been built between 1920 and 1925. To get the exhaust valve in time,
turn the engine over to about 10 degrees before bottom dead center.
At this point the cam should just start opening the exhaust valve.
Turning the engine in its usual direction travel (so as to take up
the slack in the linkage and gearing) the exhaust valve should
close just ahead of top dead center. Since the intake and exhaust
cams are in a fixed relationship to each other, further adjustment
of the valve timing can usually be accomplished with the adjusting
screws on the rocker arm. Each builder had their own ideas of
proper valve timing, so it may be necessary to move the cam gear a
tooth or two one direction or the other. We have found that the
original timing marks are not always absolutely correct.
Occasionally, experimentation is required to improve performance.
By performance we mean having the engine operate with no load for
hours at a time during a show without causing any problems.
Cletrac and Alamo colors, ake Zilverberg, Little Pine,
Route #4, Aitkin, MN 56431 writes that the Cletrac of the late
'30s and early '40s was a brownish orange, much darker than
AC orange. Also, the Lindsay Alamo engines were burgundy. Mixing
gallon of International red with 1/3 quart of Royal blue seems to
match it very close.
