carb. rebuild

[Skools Out]

here's the pictures
This is one of the carbs off a 225



these are the high / low jets clean them out. i take them out usually and clean in laquer thinner or just blow air in them to keep open. just don't mix them up and make sure all carbs have the same jet numbers. these are as follows upper is intermediate orifice #47 and lower is idle air orifice #34 in this case



Under this is the main fuel jet take to cap out and fuel should run out there is a number 62D or 63D jet in them usually. these are know as the High speed orifice #62D in this case



this is the air passage port cover can remove it and clean that too it will get stopped up too.



can open the bowl area / float chamber. this has the float, needle, and seat.



you can do these with out needing a rebuild kit.just be careful opening the covers without hurting the gaskets. Hope this helps

If you are going to go through the trouble of removing the carbs and disassembling the jets and float bowl, why not just clean them and rebuild them with new gaskets, needle, seat, and float. The kits are like $25 each. ???

i would just clean the 2 smaller jets first with air plus to rebuild 6 of them is $150 for the kits and to clean is just FREE spare time.
