I take your in the process of rebuilding the motor?

There is a retainer shaft inside (what the screw you removed screwed into) that snugs up against the carb. Using a hammer and a punch/screwdriver............LIGHTLY tap this shaft in one direction and then pull and pry, then lightly tap in the other direction and pull and pry. Eventually it will come out. Sometimes I've had to actually hit the bottom of the carb (towards the bottom of the engine) lightly with a hammer to pop it loose. HTH, Doc oh ok i couldnt get that out i tried i ended up using a pair of pliers and yanking the carb out that worked ok im in the process of cleaning it right up, i bought a wire polishing tool for the dremel to clean up the head and button its done quite a good job. ive just finished cleaning every part have purchased some liquid gasket to make a good seal on everything when i reassemble. am about to do that now hopefully the engine will still go when i put it back together :) its my first attempt > > How does one remove a carby from the engine? > > at the base of it there is a screw ive taken that out thinking the carb [quoted text clipped - 10 lines] > > Doc > oh ok i couldnt get that out i tried > i ended up using a pair of pliers and yanking the carb out that worked [quoted text clipped - 8 lines] > hopefully the engine will still go when i put it back together :) its > my first attempt I don't know about anyone else but I wouldn't put any sort of gasket sealer on the head. If the shim is ok and has know burrs then that should seal it well enough. The other problem with using sealer is getting it inside the motor. It might make future disassembly very difficult and could stop the motor from hitting TDC when you first start it up.

That's it. RTV should NOT be used on the head gasket.............EVER!!!! Doc ok i didnt use it on the head everywhere else tho heres a before and after shot http://users.on.net/~annecarl/cylhead1.jpg http://users.on.net/~annecarl/polishedhead.jpg > ok i didnt use it on the head everywhere else tho > > heres a before and after shot > > http://users.on.net/~annecarl/cylhead1.jpg > http://users.on.net/~annecarl/polishedhead.jpg Beeeee-oooo-tiful!
