Jawa 207 with A38 installed with cover off
The chrome replacement Jawa petcock A38 is at left. Original is at right. The handle does not stick out of the hole in the side cover like the original did. So it is a little hard to reach but not too hard.
16×1.5 spigot down N/A
16950-045-005 Off-On only
In most cases, spigot right (above) can substitute for spigot down. The valve can be aimed at any angle, so “right” can become “back”.
Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow left (handle right), on is arrow up (handle down), reserve is arrow down (handle up).
A36 (bottom) 16×1.5 spigot right $20
↑reserve ←off on↓ made in Taiwan
This is a vertical mount valve for ’82-83 Honda NC50I Iowa, and some 60’s and 70’s Honda motorcycles and ATV’s.
Indian valve substitute: The threads fit an Indian 4-stroke moped. This valve A36 will substitute for an Indian gas valve A35, but the cover panel would have to be left off. With the cover on you cannot reach the handle.
Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow right (handle left), on is arrow up (handle down), reserve is arrow down (handle up).
A36a with reserve $34
A36 is a modern substitute 16×1.5, made in Taiwan. It is a vertical design, mounted horizontal. The cover panel must be removed, or a large hole cut, to allow access to the substitute valve. There is no reserve capacity on the substitute, since the reserve tube is horizontal.
A36a is valve A36 with a added aluminum reserve tube that curves upward.

A35 is an original Indian 16×1.5 side mount, made in Taiwan. All 3 rubber seals have decomposed.
The 2 seal rings do not normally leak if they are undisturbed, but the seal disk does. There are two ways the seal disk can leak.
1) It can keep supplying the carburetor with gasoline when in the OFF position. This leak can be stopped temporarily by pinching the fuel hose with a small vise grip or C clamp.
2) It can leak gasoline outside of the valve when the handle is in any position. Other things besides the seal disk can cause this kind of leak. Some of those things are: improper assembly, damaged handle plate, missing wave washer, damaged valve body, pieces of the old seal disk still stuck to the valve body sealing surface.
Outer seal ring: The 17mm substitute outer seal ring sits in a 16 mm groove. But it has to fold to pass over 14.5 mm thread tops on its way in, Once in it can be unfolded and does fit, but tightly.

This is valve A32 with a curved-up aluminum reserve tube added, for side mount use on KTM. The cover panel must be removed, or a large hole cut, to allow access to the substitute valve. There is a reserve capacity on this valve, because the reserve tube curves upward. So the “on” inlet is 2 inches higher than the “reserve” inlet. The bottom 2 inches of the gas tank would be reserve.
