I'm having issues with the float level on this rebuild. I cant remember having this much trouble on the last build. I'm surprised that it cant find a lot of information about it on this site. I figured that would be one of the basics to share information on.haha.
I started the engine for the first time after the rebuild. It started up within 2 seconds. I will say I was pleasantly surprised. It ran good, but it started flowing pretty bad with fuel out the top of the carb. When I pulled the side screw to check the fuel level in the bowl. Fuel flowed out of the hole confirming something is wrong. I believe the fuel should be level with the bottom of that hole at idle.
I pulled the carb and checked the seal on the needle valve, and it was good. The floats are sitting at a parallel position to the gasket mating surface. What i dont understand is, the book says the top of the float to the casting surface should measure 1,1/32". It also says the top of the float should sit below the top of the bowl 5/8". Which should rest with the top of the float level with the bottom of the side access hole when looking in to it.
So I know the fuel is constantly flowing up to the top of the bowl and forcing its way out through the screws. There's no point in cranking the screws down to strip them out because the fuel should never get that high in the first place. People say to put the floats level with the gasket mating surface, but that doesn't allow for the 1,1/32" measurement between the top of the float and the gasket mating surface. Its around a 1/2" or so higher then that measurement on mine.
I know this sounds redundant, but i just want to be clear here on my situation. If someone could please elaborate on a better briefing of this whole setting the float level process. From where to start measurements? From the the gasket mating surface with, or without the gasket on? From inside the top of the casting just bellow the gasket mating surface? Do you measure from the highest back portion of the top of the floats? Even how to adjust your floats if they're bent and need reset and you dont have a gauge? It would really be awesome if someone had exact measurements of the gauge used so someone could make a gauge for future use.
I know thats a lot to ask guys, but I cant find a lot of intel on here about all of this carb set procedures. It would be nice if someone could share thier years of knowledge and decipher the book better by giving a good briefing on this subject.
Thank you so much to whomever sacrifices thier time on educating me better on this. It will be vital information for guys in the future as well. I look forward to any, and all comments to enrich this subject.
Thank you gentleman,
Mark Kish
