Service advice needed...

[stoveguysford]

Hi. I'm servicing my '42 GPW and have hit a snag. I have found a mouse nest above carb. Cleaned system out to the air filter but still have debris in the intake manifold. I have vacuumed the carb while turning the engine, no plugs, yet I can still see debris. I fear the carb mounting bolts are frozen. This girl hasn't been started in years. On another note, do you suggest diesel as a rinse in the crankcase? Thank you all for the advise, in advance.

Best to remove the carburetor and try to suck it out or remove carb , PCV and all plugs in the intake in order to blow in some high pressure air. If it were mine and the engine appeared to be in good shape, I would remove the manifold and peek at the valve ports. Turning the engine over may jam debris into the valves, which is not a good idea. Attempting to start it with the nest in the manifold most likely will not be successful due to disruption of atomized fuel flow.
It is doubtful that the nuts attaching the carburetor will be frozen.
Use your best wrenches.

I have soaked the carb nuts with PB Blaster for two days. Have not put my best wrench on it yet as the aft nut has an accelerator bracket under it and is in the way. Don't want to bend anything. More later...

Got it off...I'm into the manifold and i have quite a pile...Isn't wildlife wonderful?

Get some high pressure and don a dust mask, you might want to blow thru the spark plug holes first to keep the mess at a minimum from entering thru the valves. Turn the engine over slowly while blowing each cylinder. The goal is to keep whatever enters the valves to a minimum. If it were mine, I would be doing it differently and probably remove the manifold. I've started a lot of equipment that has sat and have witnessed a lot of cooked acorns and singed chipmumks come out of mufflers.

Okay then. I shall be looking down stream as well. Thanks again. Any input on the diesel rinse? An old chainsaw buddy suggested it...

I would avoid the rinse.....sounds on the bubbarish side. Just change the oil and filter. If its been sitting you may want to drop the oil pan and clean the sludg that settle. Another place sludge likes to settle is the oil filter housing. Diesel is a solvent and may do more harm than good. If you insist on a rinse use seafoam or MMO....but still really don't see that it's necessary.

I too know about the acorn machine gun. Nothing like starting up a project bike only to have years of acorns and sunflower seeds get blasted out the exhaust pipe......does smell pretty good though it also makes a hell of a mess in the garage!!

It is best to see if it is going to start up and run, then you can change the oil hot. Flushing is not really necessary as it may not cut thru old sediment that has hardened, that is best removed by removing the oil pan. The hot oil circulating thru the lubricant passages at operating pressure will do a sufficient job.

Hats off to The G! She started yesterday. I am so excited, I could pop... I wish you could have seen the glow in my wife's face when she saw it running. This jeep is 70 years and one week old. I hope I run that good at 70...
I vacuumed out through manifold and collected quite a pile of stuff. No troubles in the exhaust except for a hole to mend. I found a pinhole in the tank and patched that. The sump under the tank was full if sand, rust, a wrench (Canadian Crome), a table knife and two tank strap nuts. It took me a bit to get fuel to carb as I have no prime handle on the fuel pump. I found a bit of fuel in the filter and filled the cup to speed the process. Off she went with a full cranks; what a wonderfull sound.
To me, there is no sound quite like a jeep. I always look when I here one coming.
Today, we will DRIVE out the barn door and take a lot of pictures. May be I can get Mother to come along...
Thank you, G.
