Title: taking apart carbs
Post by: haler on June 15, 2015, 04:13:00 PM
I'm trying to clean the carbs on my 86 fj1200 and 2 of the float pins will not slide out and I'm scared to beat them to hard.  Any advice on how to get the out?  I've sprayed the shit out of them with carb cleaner and pb blaster and they won't budge

I have used a sharp blade tapped lightly between the pin head a float post. The blade acts as a wedge and the force is in column with the post so less likely to bust it off sideways. An old wood chisel might do the trick. What ever you do, if you put a side load on the float post, make sure it is supported from the back side.

Stop where you're at before something possibly happens that you may regret, and that would set you back some cash and time.

Read through these, then you'll have a clearer picture of what you're facing and how to best tackle your carbs cleaning and refurbishment.

I was paranoid about getting those damn float pins out and ended up using an automatic centre punch like this  http://www.jaycar.com.au/Tools-%26-Soldering/Hand-Tools/Other-Hand-Tools/Automatic-Centre-Punch-%28Prick-Punch%29/p/TH1770 (http://www.jaycar.com.au/Tools-%26-Soldering/Hand-Tools/Other-Hand-Tools/Automatic-Centre-Punch-%28Prick-Punch%29/p/TH1770)

you don't hammer on it, but push and the spring inside delivers a small blow each time, works quite well.

Ray, did you file the tip off the punch?

No I didn't Noel, and now that you mention it I probably should have. But it still worked well.

Whenever I work on new carbs, I'll take some 600 grit to the float post to lessen the fit.  In the past I've also drilled out the post itself for more clearance.  When reassembling, I never seat the float pin all the way but leave a slight gap to get a knife blade behind just in case.  The float bowl has a recess that "should" prevent the pin from backing out on it's own.  I've never had a problem with a pin backing out.

I use an electronics flush wire cutter to ease the pin head away from the post ..
