45 B

[soldiertom]

Last August I was given a 45 B that was semi converted to an electric start tractor. After fixing everything I saw obviously wrong and putting it back together from parts gathered and given, I was ready today to try and turn the engine over and see if I could find anything else obviously wrong. We belted it to a 51 VAC and rolled it over without plugs to just get everything freed up. It had been at least 10 years just sitting in a ware house in Nashville following a refurbishment at some time in the last 15 years or so. After a while of rolling the engine over, and verifying that oil was indeed moving around to the rocker arms etc, we added gasoline and spark plugs to the equation and tried it to see if it would fire up on its own. Well it did fire and it would run; but not smooth at all. The engine would just about die then pop pop pop, then just about die then pop pop pop.
Im thinking the gov'nor needs attention. Am I correct? Or could it be a carb issue? I had the carb rebuilt about 4 months ago, and it was put on the tractor in the barn but never ran till today.
What are your thought folks? I appreciate your expertise.

Could be governor, but is the linkage between it and the carb ok? No binding, on anything else odd? Odds are it is in the linkage or carb.

 

[soldiertom]

I didn't see any binding points, and the governor kicks in strong when it catches, so I was thinking Carb'rator as well. Any suggestions on what to do first? Like I said, about 4 months ago I had it rebuilt, should I do that again rekon?
Walk in peace

Carb still has passages plugged. They have to be drilled out.

Sounds like an idle circuit passage is plugged, the governor is doing its job by opening the carb to keep the engine running. Do a thorough job of cleaning all carb passages and I bet your problem is gone.

Unhook the governor linkage at the carb and control it with your hand. Is the governor linkage adjusted correctly? They are pretty sensitive to length changes

Have you tried opening up the idle jet. Open it a half turn or so and see if it improves.

First thing I would do is run a compression check on it. If the compression is down then so is the vacuum that pulls the fuel to the cylinders. You don't say whether it's smoking when it's running or is it starving for fuel. Might want to check that. What is the condition of the valves? They could be burnt or not seating properly due to carbon buildup. Hope this helps. RW.

Well, in my world, when one pays for a service and said service didn't get performed or performed correctly, provider gets a visit and either rectifies situation or returns money for said service. Request he show you how the carb runs on an actual tractor. If he won't/can't then that means he never run it before you got it. In that case get your money back because that should be part of the service. It's your money, give it away if you want but that's where I would go next. A reputable builder shouldn't have a problem re-installing it and running it even with you there if in close proximity.
