Six Pack issues and rebuilding by tommyg29

3 minute(s) of a 193 minute read

after sleeping on it I think one of the carbs (probably the front because some fuel did come out when I removed that sight plug) was stuck, and the electric pump just filled the cylinders and then then the intake manifold and into the vacuum line to the brake booster, and probably some if not a bunch into the crankcase.

Correct me if Im wrong but what I will do next is remove all spark plugs, drain the oil, try to suck any fuel out the brake booster with a tube, and then put some cheap oil in the engine, and then turn the engine over a few times without plugs (and maybe check compression while Im at it) with the ignition disconnected and electric fuel pump off to circulate a little oil with some flushing action. Then put plugs back in, reconnect everything and try to start it up. And VERY soon after change the oil again.

Of course, I need to also check and repair the carbs.

Sound OK?

Thanks for the great advice. Will be picking up some new champion plugs (RJ12YC) and having a busy weekend.

Hopefully I didnt break or bend anything.

Oh yeah,

probably at least a gallon of gas came out the uncapped opening in front of the booster.

Now Im trying to figure out how to get a micro fuel line down into the booster to try and get fuel out. Its probably full and maybe ruined.

Will be draining my oil tonight also.

PS

Just drained it and the first couple quarts were oil so I figured, ok, cool. and then a torrent of the lighter than oil fuel started gushing out. Easily more than a gallon, so far. Stuck the plug back in for now before it overflowed my 3 gallon oil bucket.

Checked the brake booster and it seems dry so I should be lucky there.

And another update, there was probably 2 gallons of fuel in the case, and then I pulled the front carburetor and will take a close look at it. 

Will put some cheap oil in it and a quart of an engine "flush" oil, put the new plugs in it and run it lightly a few minutes and drain again and put the good oil back in.

Im using a mallory pump, and yes when I just let off the gas the engine seemed like it was only running/loping on about 4 cylinders as I coasted home.

I read online more than once that even the holley kits typically have gaskets that have extra holes or sometimes you have to punch them yourself.

Never done a full rebuild on any carb other than for a small engine (lawnmower/trimmers)

I have all 3 carbs sitting on my workbench and have the float bowls pulled. Everything looks fairly clean...no gunk or varnish.

Local parts stores dont have the rebuild kit so now looking online.
