RE: veco 19 tuning and running suggestions
Ok, im back with some pics in my gallery, so check them out. In the midst of waiting for responses, i decided that i would make a muffler out of some aluminum, so I got to work to fix my problem. I got the muffler done, and I was happy with how it looked, and how it helped the fuel draw, (i can now have my tank below, were it is meant to be) but it still stalled at full throttle, or even half throttle. So i tinkered around some more, and I found a air leak that I had missed before. The place were the throttle barrel rotates, it has some packing, or gasket material to keep it sealed, and it was worn out and was leaking. My solution for that, as you can see in some of the pics, was to cut out a circle of leather from some work gloves and use that! I had to use 2 layers to keep it from leaking, and I lubed the leather up with some wd40 so the throttle still moved freely. While I had the carb apart, I made sure it was clean, and reseated it in the intake and made sure I had no leaks. started her up and tuned her at part throttle, and then cranked her up and it kept running!! [X(] I was thrilled, it worked! Did some final tuning at top speed, and now it runs like a champ, and i cant wait to try it out tomorrow at the lake. The radio and batteries are on the charger for overnight, and Ill be playing tomorrow after work. Even though the muffler wasn't the problem, I liked making it, and i think it looks cool. It even quiets it down abit. I read that one of you mentioned that the baffle was how you controlled idle mixture, now that i have the muffler instead, I cant control it can I? It idles fine, however if it sits at idle for a very long time, and then i go to throttle up imediately, it sputters for abit, cause i think its running just a tad rich at idle, but it doesn't really seem to effect performance or idle, so i should be fine, I would think. The muffler tip that i welded on my muffler I made, i drilled a 1/4" hole through it, I went by approx size of other stock airplane mufflers I had. The muffler I made wont harm the engine will it? I wouldn't think it would, but I figured one of you guys would know for sure so i would feel better knowing its ok.
Thanks again for your help and suggestions, I really appreciate it, and I am glad to have found this forum. I am looking forward to learning a few things, and sharing what I know.
Thanks
