RE: Welcome to Club SAITO !
Chuck,
No problem with the questions.
You use the two screws that mount the carb to the engine.
The velocity stack bracket stradles the carb.
It is an easy job to put it on.
Once you get one you will see immediately how it works.
The Saito 1.00 on the UCD .60 works great!
I had no problems mounting it except I had to switch the carb orientation...swing it 180 degrees to make the throttle linkage work. Again, an easy job.
I have unlimited verticle with a 15x6 APC and Sig 25% nitro 20% oil, 50/50 castor/synthetic.
I have around 7 gallons of fuel thru mine now.
The first couple gallons was Wildcat 15% nitro and I still had unlimited verticle.
I hope this answers your questions.
Feel free to ask away any time!
Good luck!
JLK
