took the mta4 out today and actually got it going. I had to lean it off loads (HSN) but it seemed to be much better and ran at a good temp. However the one way bearing started to slip every couple of pulls and then it just went completly. I took it out to have a look and it seemed fine but when I put the pullstart assembly back it slipped again. After taking out and putting it back together again a couple more times it stopped slipping. I took it out again and now it won't start. I tried to richen it back up a little but all I got was some very nice blisters.
I am using tornado 25%, standard MTA4 pipe.
Also with my sts.12 there was loads of compression and it stuck at the top for a while until it was broken in with the .28 the pull start pulls really easy if I did not know it was new I would think it was 6 months old.
