Thanks for all the help people, you know who you are. Some of the conversations you were having on this form helped me refigure and re check the issues with the set up on the Syssa.
I have a Zenoah G26 that I have never had an issue with. The guys at my club have never had to mess around with their DLE or 3W's so they did not have any trouble shooting experience.
This Syssa was an issue for the start.
1. the engine would no run with the factory settings (???)
2. screen in the carb was plugged with what looked like saw dust. ( during the build contamination?)
3. the mesh looking diaphragm on the carb was ruined, it had a big bubble on it where is should be flat. (Bad gas?)
4. installed a new carb and the updated muffler
5. motor would still not run on the factory settings. (vacuum leak?)
6. cleaned carb screen
7.removed the fuel filter, made the fuel line shorter, rerouted the fuel line, set carb at factory settings, engine now runs.
The big issue I had is getting over the fear of getting next to the propeller to tune the engine. I can hold my hedge trimmer, chain saw, leaf blower, etc and mess with the carb until I get it right.
The engine has spinning hand remover 6 inches from the work space. I have an idea that may be a solution for this, I'll share it when I am done
I hate to say this, but it seems like you are trying to blame the engine for things that you caused. 1. and 2. Both may be caused by you. The odds of the engine being delivered to you with sawdust are pretty slim, metal shavings yes, sawdust no. 3. A bubble on the carb diaphragm, may also be caused by you, if you plug the fuel inlet, or allow it to become plugged by FOD, and turn over the engine, the carb diaphragm can be deformed because it will be pulling a vacuum. 5. The vacuum leak may be caused by you, the part you added was not part of the engine, but it caused the engine not to work. It is hard to blame the manufacturer for that.
As far as your fear of adjusting the carb, this gas engine has the carb in the rear, it is hard to get the screws any farther away from the prop. I don't know how you ever adjusted a glow engine that had the adjustment screw 1/2'' from the prop. A sic inch prop can do just as much damage as an 18'' prop.
I put my plane on the starting bench, shown in my avatar picture, one can be built for under $50 and free plans are posted here on RCU. You can't use the RCU search engine to find them, but Google will work. That is another story. I use a long screwdriver to get to the screws. I have little brass collars on the screws to keep the screwdriver from slipping off. Some people use plastic tubes on the screws. I always stand behind the engine and prop when I make adjustments. Have not had a hand in a prop since 1948.
Your reading too much into the post, I'm not raining on the SYSSA fan club, it was meant as a checklist of how I got out out this mess with the help from others on this form
no more no less
It was my attemp to help others
On a nitro engine one grasps a thumb screw and twist it, a plane that you can stand behind/beside and the screw is on top of the plane while its running.
On this Nemesis gasser one has to try and center a screw driver (12" long) on a vibrating slot in a screw underneath the plane while its running,,,,HUGE difference.
