Home again... and none too soon

[Merle Coggins]

As I was rolling into town my truck started acting strange. I pulled away from a green light and all was well until I shifted into 3rd. When I continued to accelerate through 3rd the truck started bucking and acting like I had hit a rev limiter, but I hadn't even reved it that high yet. So I short shifted into 4th and it ran good from there. At the next light it did the same thing. Hmm... After that it seemed to be OK, but I didn't need to run through the gears the same way after that.

When I arrived at home I backed up into my driveway, and just as I was getting to where I wanted to park to unload "the TV" the engine stalled. "No problem", I think... I'll unload everything then fire it back up and finish backing it into it's parking spot. When the time came it wouldn't fire up no matter what I tried. It would pop and try to fire, but never would run. I finally gave up and decided to give it time to cool down. I'll go out again in a few minutes, after it's had a little over an hour to cool off, and try it again.

I wonder if it's time for a new coil. I just happen to have a new on on hand that I got "as a spare".

I may be off track, but I'm thinking this may be a fuel pump or supply problem. Maybe a fuel filter clog or begining of a pump failure or crud in the fuel. Doesn't sound electrical even though I don't know enough about failing coil symptoms to give an opinion. I would switch to your spare coil as a simple first step of eliminating causes, then check out the fuel flow. Let us know what you find.

Well, it refired after sitting for a little over an hour. But I had to hold it wide open while cranking. So I suspect that it maybe flooded too. I had to do the same thing last night after unloading the TV at our Eau Claire shop. Ususlly I just have to give it slight throttle when I crank it up hot, but last night I had to hold it to the floor to get it to start.

I may have multiple things going on. I'll put in the new coil, and lower the float level. I need to fiddle with the accelerator pump again anyway. So while the top's off I'll lower the float level. I'm getting a slight cough under acceleration again, maybe a clogged jet. I also know that I need a new spring for my heat riser. It moves freely, but doesn't work properly. I suspect that it may be staying open and over heating the carb. I'll wire it shut for now until I can get a new spring. Anyone know of a source for them besides Bernbaum?
