It's been sitting 5 years. I started some work way back, and well, one thing led to another, as is how sometimes things go.
Didn't do any real major work on it, except to replace the halfshafts and front wheel bearings.
Everything is back together now and I did the following:
. changed the oil / oil filter
. installed new spark plugs (squirted some oil in cylinder before install)
. sprayed carb cleaner in carburetor to loosen up some of buildup - choke plate was a little sticky at first
The engine won't start. At this point, I can get it to start up, but it won't stay running. Here's what I've determined so far:
I can see a stream of fuel entering the carburetor with each pump of the accelerator (or via the linkage at the carb). The vehicle starts on this, runs (sometimes as long as 30 seconds) but stalls I'm assuming after it burns this fuel off.
The vehicle utilizes a mechanical fuel pump. I disconnected the fuel inlet line from the carb and directed the line into jar. It pumped a lot of fuel when starting/running, so I don't think there's a problem with this. I know this fuel is old, but it looked very clean.
I disconnected the fuel inlet line at the fuel filter and plugged this line. I then routed a long piece of fuel line from a container of good gasoline to the fuel filter. Upon trying to start the vehicle, fuel was being drawn from the container fairly rapidly -- I'm assuming most of it was being returned to the fuel tank (two outlets on the fuel pump, one to carb (actually, to another canister, then to carb), and one back to tank). There was no change in doing this; car starts with some pumps to accelerator, then quits.
Now, I did get a long running start from the engine by directing a continuous spray of starting fluid into the carburetor, while someone turned it over for me for ignition.
I think I'm definitely dealing with a fuel problem here; I'm wondering if I should dismantle the carburetor and clean it all out? Also, I know the gas is old, but it looks clean and I didn't get any change in this problem when routing new gas to the fuel pump.
One more thing, when the vehicle starts off starting fluid/fuel poured in carb, and it runs, if I throttle it, it immediately stalls -- I'm not sure what this indicates??? Also, the vehicle will not start with the accelerator pushed to floor (only pumped prior to starting).
I appreciate any comments - thanks...
. I did check (and do have) spark on each cylinder
. oil pressure guage does indicate oil pressure with each brief start/run
