Need Help I can’t get Johnson 55hp Motor to run right at all

[brodyg201]

ok so i need some help . i have a 1977 Johnson 55hp 55el77d and it wont idle right . it will idle now but in gear i have to push the choke every so often. but it will idle in gear when i run it around full throttle for a bit but as some as it is off for 5-10 mins it starts acting up . so i rebuilt the carbs and also put a new feul pump on . nothing different and when i pump the primer gas comes out the carb . and i just found yesterday the the motor isn’t charging the battery now so any suggestions that would help thanks .

Might as well get together all the info you need to get answers....first, need an accurate compression test in each cylinder with real numbers. Then check the spark jump distance with a spark jump gap tool from auto store.
When you rebuilt the carbs, did you actually do a complete rebuild with the proper factory rebuild kit and set them to factory specs or did you jyst take them apart and clean them ? Once you get this info posted, others will jump in with more suggestions.

Gas leaking out of the carburetor means that float / float valve need attention.

i replace the needle and seat and float and tested it by blowing into it

I can not see your carburetors !----If gas leaks out there is an issue with float or float valve.----Did you install factory carburetor kits?---Or a " good deal " from Amazon?

it was a kit from amazon

And those include no information on adjusting and setting up your carbs for that particular motor.....factory kits do......

old style carb clean all orifices see misc utubes on how to clean old carbs
use carb cleaner and blow out with air compressor. check side channel passage leading to the top IDLE circuit and under the dime size plug
reassemble air should blow IN upside and N o air should blow in with carb held upside down !

Get an OEM or Sierra kit and try agin.
I have seen many cheap amozon kits with miss matched needles and seats which would explain your leaking carb. And follow Crosbymans instructions when cleaning.
Best

Amazon kits appear to be junk.----Marketed by----hooflungdung----company.

side question while i was working on the motor i am replacing the impeller . because i have no idea what condition its in. but the lower unit is stuck i triple checked all bolts are out . and the front has a gap, but the back won’t come apart any advice ?

You removed trim tab ?--Hidden bolt there perhaps.

Maybe the driveshaft is jammed into the crankshaft with rust.----Shift rod is disconnected ?

If your sure everything is free wooden wedges can be your friend. Sometimes these this can be a bear but patience pays and then sometimes they win the fight.
