Busted air/fuel screw stuck

<< < (5/5)

Shark Racer:
Neat. Looking forward to it.

Thanks for the explanation!

Do all the 4Ms have this setup or just a few?

PMD1969:
Well... it hs been a while and I have tried putting some MAPP heat to the affect screw.  No dice.  I heated it up and run some wax in it.  Then tried to clean it out reheat and put some PB in overnight.  Then tried to cut slot down the middle and used a small flathead to turn it.  Broke that.
