Friends grandpas tractor, again and again.

Postby LRiddle » Wed Aug 02, 2017 7:08 pm

I tried to drive the thing today and like I figured, it has no power. I can get it to idle smooth and sweet, but I was suspicious of how it would be under load. I can only get it to drive in 3rd gear if I start in second downhill and then double clutch into third (I know I know, you aren't supposed to shift on the fly).

So the question before the jury is...
I took the fuel line off the carb and I have good fuel flow there. I put the fuel line back on the carb and pulled the plug at the bottom of the carb bowl, viola, no where near the same flow. So should I see the same amount of flow through the carb bowl as I do from just the fuel line itself? If so that would mean something with the needle and the float isn't jivving I assume. The float is adjusted correctly (thanks to Bob McCarty for the knowledge and tool) and there is no fuel inlet screen and, if you've been following this headache, you know it has a fresh needle and cage and other inards in it. Also has spent plenty of time in a carb bath to eat up all the crusties lurking inside. Help me before I tell my buddy to come drag this heap out of my shop.

First off, what is the overall shape of the engine? What are the compression readings? Has the timing been set correctly?
If you think it's problem is fuel related my guess would be a partially blocked main jet.

I haven't done compression tests, but I'm pretty confident that the engine has the power, I just can't seem to find where it's hiding it.

Ok, it seems I may have it figured out. After having the carb apart, again. :roll: I put the old all steel needle back in with the old cage, readjusted the float (thanks Bob) tinkered on this and that, and then my slow brain finally caught up to me eyes and noticed that the yoke on the govenor to carb rod seemed way shorter than that of the one on my beast. I decided to goof around with that for a minute, lengthening the rod 1 turn at a time until I seemed to hit on a sweet spot. I got it to where I can go to high throttle quickly instead if babying it like before. I took it for a spin and was able to start off in third gear up the same hill I had to roll down in second earlier today. So it would appear that I am on the correct path, I just didn't realize how much that govenor adjustment meant apparently. I'll tinker some more later and hopefully get it dialed in. Fingers crossed.

To be continued...

Sounds like you're onto something there. Glad to hear it's running better for you. :coffee:

I guess it just threw me off because it was running smooth, so the govenor wasn't something I had suspected.
