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.
Hi Matt,
You can try to clean the one-way bearing with some cleaner. Lubricate it with some castor and try again. If it still slipping you may need a new one way bearing. Heat the adapter and replace it.
it seems your engine still too rich,try the setting;
HSN- 1.5~2t out / LSN- 3~4t out
We have to let the pull-start engine more loose otherwise it is real hard to pull when it new. You will get more nice blisters if it is as tight as our .12 engine series.
by the way,If you would like to use Tornado 25% on off-road purpose,i would suggest you to add 2% castor or more.
Regards,
