RE: MVVS .26 engine setup
Jim, Thanks for the note!
I worked with it the other night and finially got it going and running somewhat good......
I an using Byron glow fuel, 10% nitro/20% castor. With this small engine it was setup on the plane w/o a nose cone so I was chicken stick starting it. I think where I ran into some problem was when my chicken stick was bumping the needle valve on my up stroke and was leaning the carb. I had a buddy come in to help me figure this out and after quite sometime we got the engine going and it's running pretty good right now. I found out I can get my electric starter on the nut and washer and can spin it over w/o chicken sticking it. It still has a little mind of it's own and needs to get wound up quite a bit before it fires and gets going so I still ma need a little tweaking. The guy I bought this from said the MVVS's take a long time to break in and from the looks of it it's still pretty new. When I did get it up and running it was a big time screamer, esp. with my tuned pipe on it. I used my tach on it and got a 17000 rpm reading.
I have briefly heard of the pinch test but if you could explain it to me in detail it might help with the tweaking. Thanks again!
