AC-816 (MTF Newbie!)

Hey guys, brand new to MTF!!! This site rocks! My father and I are trying to get my grandfather's 1984 Allis Chalmers model 816 tractor up and running. We are running into a few issues maybe anyone can help?

1) In order to start the tractor we need to "jump" the solenoid. We tried to replace the solenoid but still didn't help. I know that there are three safety's on the tractor (Neutral, PTO, and Clutch). We tried to bypass that Neutral safety.... How exactly would we do this? I think when we were trying to bypass this safety we might have also shorted something out because one of the leads accidentally his something it wasn't supposed to hit and sparks were flying.

2) The other issue the tractor is having is that it runs OK in 1st gear, but anytime you throw it into a faster gear it will choke out and stall. We are going to take the carburetor out and clean it out. Would this help? Might it be another problem?

I can't imagine much is wrong with the tractor, it was only used to cut grass, and stayed in a shed 100% of its 24 year old life.

Any help or hints would be great!!!!

Your tractor is a twin to the Simplicity 6216. If you don't already have them, you can download the manuals at http://www.simplicitymfg.com/manuals/index.cfm?rd=1http://www.simplicitymfg.com/manuals/index.cfm?rd=1

You can bypass the safety switches by taking a piece of electrical wire about the same gauge as the wiring harness about 6" long, strip the ends, form it into a U shape and plug one stripped end in each connection of the terminal you remove from the safety switch.

Cleaning the carb can't hurt. How long has it been sitting since it was last used and are you using old gas or did you put fresh gas into it? If it has an inline fuel filter, replace it with a new one. They are cheap. Run a product like SeaFoam through the 1st tank of gas to help clean everything out. Marvel Mystery Oil is also a great product to get everything working in the fuel system again. Make sure the governor is working properly. A new spark plug would also help if it has been sitting for anytime.

Does it accelerate ok in neutral and 1st gear? As far as the starting of it, check for any inline fuses or circuit breakers. Check and clean all wiring connections. If you have access to a multimeter, you can quickly run down the problem of why you are not getting current to the solenoid switch. Just a few thoughts on places to look for your gremlins. Keep us posted.

Wow thanks for the info! I found my project for tomorrow! I tried looking up the manuals on the website you suggested but the Model #6216 is getting any results. Maybe the Simplicity website doesn't supply manuals for tractors from the early 80's?

Thanks I will keep ya'll posted on how we do!
They use the mfg. id number, which in your case would be 1690688. Sorry, I thought it would transfer on the original link. Just plug in that number and the available manuals should come up.
