Replacing ZS Carb Jets

Fellow Scions,

Thanks to all who responded on my question of where to find the carb jets for my '74 TR6. This people on this list are a great resource and I truly appreciate everyone taking time to repond to my request.

I thought I'd summarize what I found out for the benefit of the list:

1. Turns out Apple Hydraulics does carry them. I talked to "Bob" (very helpful and friendly) and the jets are $15.00 each.

2. Despite what may have been said by some suppliers, the pressed in jet is replaceable. Apple Hydralics uses a brass honda valve guide (which Bob offered to provide) to press the jets in and out. The soft brass prevents damage to the jet.

Here's the procedure outlined by "Bob" from Apple:

1. Remove the carb fuel bowl, top cover damper cover and piston.
   
2. Using the valve guide, drive the jet downward toward the fuel bowl. Note the position of the jet (ie, how deep is it inset from the carb throat) before tapping the old jet out.
   
3. Insert the new jet from the bottom of the carb. Using the brass valve guide, carefully tap the new jet into the same position as the old one.
