912ULS muffler

I have a 912ULS stainless steel muffler , for ring mount for zenith 701. The muffler had a weld repair a couple of years ago. The weld repair needs repairing again. The repair is where exhaust tube #4 enters the muffler. A new muffler from zenith is almost $1000.00. I will accept $700 and you pay shipping.See More

Dual throttle Rotax 912ULS

Posted on March 31, 2019 at 10:36pm 2 Comments

I have a dual throttle setup on my 701 with a Rotax 912ULS This is the kit that zenith provides with two cables. There seems to be a lot of pressure pulling the two throttle arms on the carbs back to full. If I take my hand off the throttle it will advance the RPM greatly. I have to tighten the throttle lock down very hard to stop this action. Rotax says not to change the carb springs. I took the springs off to see if it was a cable issue , but no problem with the cables. I did reattach the…

I need help on how to make the mixer lever move smooth. I made several triangle horns to make it work. the whole thing gets stuck open or closed at times

I have spent too many hours on this task which I thought would be easy. HELP

Pictures would be nice.

firewall Boots 701

Is there some type of boot for the two threaded rods that control the front nose wheel? Trying to keep engine compartment smells from entering the cabin area.

The numbers I posted are steering boots for a 2001 Yamaha mountain max snow mobile. One number is the rubber boot and the number the metal ring to attach to the fire wall. Keep working on your 701 you will enjoy flying it. If you like I can send you a photo.

Jerry,

        #609 is very early and most engines of that time have since had later version heads fitted for better cooling.

Some engines run well for reasonable times and it may be a case for leaving alone. 

You need to check what changes had already been done, if its already run 367 hrs the way to check for the scuffed piston skirts is to ground run at around 1800 rpm for 2 mins then shut down, if the prop stops quickly without springback and is stiff to rotate by hand then its a candidate for the cylinder basenuts and hone the barrels job. This is explained better by Roger Lewis on the Jabiru Yahoo group.

In the 701 depending on cowling, cooling of the heads is likely the first issue you will need to get right

The prop I use is 64" x 30"  its pictured on my page photos made by Brent Thompson Props

Hi Jerry.  Not done, but about to finally get the doors on the hanger.  Will then move 701 to N29 and put the wings on.  Let me know when you (if you) ever get to Magdalena.  Best, jfs

Yeah to bad we can't be paid for building!

Sounds like great progress.  Which Jan are you going with, the 2200?
