M211 Carb float setting

[M2116x6]

What is the carb float setting on the Holley 885FFG carb used on the G749's? I can't find my carb manual at the moment.

Thanks,
Jim

I looked it up in the M211 manual, but it doesnt go into details on float adjustment. Has facts about the governor and vacuum things but looks like I couldnt find what you wanted. Maybe a carb specialist?

No doubt you already have the information by now, but for those who don't the flat part on top of the floats floats should be 5/32" from the top of the bowl when the valve is closed.

As of last weekend I still had not found the float setting so I adjusted the float top parallel with the bowl top. Even the Holley manual for the 885 series just mentions to set the float using the gauge. The picture in the manual shows what looks like the typical cardboard gauge. There is no mention of what the measurement is. Apparently the older kits must have included the gauge. I've reassembled the carb and the truck seems to run great.

I've been under the gun to get the truck running right for two events I will be attending this weekend. The truck was suffering from water in the fuel tank which also messed up the carb. Drained and cleaned the tank, blew the line out and rebuilt the carb and she runs great.

After this weekend I will pull the carb top off and readjust the float to 5/32".

Thanks for the replies!
Jim

Page 20 of this manual just does like you mentioned, "check with gauge." But, the picture shows the float angled a little.

On my OA331 with the same carb, I set it level and noticed a burble every 20-30 seconds after long time idles. I lowered the float just a touch and the burble is gone. Sorry I can't be more scientific than that.

Sorry guys I did not give a reference in which I should have, your right it's not going to give a true measurement in the {Disassembly and Assembly} section of the manual. As with MOST (and I use the word lightly) of the maintenance manuals all the true measurements are in the {Description and Data} sections. In this 885-ffg manual its on page 42 table 4 and will give the float setting in inches in the open setting as well as the close setting.
