I was looking at some other forums about trying to determine the year , My

990 doesn't have any model number or nothing , i don't even have the

original dash witch sucks , im looking around for one and cant find any

where , but anyhow , i wondering if there any other way of determining the

year / model , by whether it has 4 bolt pattern or maybe the muffler style or

some other way ?

Based on the fact that it has C-Clip front hubs dictates that it is a 1978 or newer. The engine does not look like the original engine based on the fact that it has a starter instead of a starter-generator and also the gas tank is not the one that came with the 990's. I am thinking that some time in your tractors past it had a crate engine installed. This will not tell us the year of your tractor if that is the case.

Around 1980 MTD used a different style 4 bolt hub rear wheel. See in link here.

Your tractor has the earlier style rear wheel. With that said your tractor was most likely built between late 1977-1979.

Thanks for the info

the guy that had it before me said it was the original motor but he said he had cut into the metal that covers the fly wheel and put that starter in cause he couldn't find one like the original one and he said the gas tank had holes in it and he replaced it with that one

Thanks for clearing that up. I say use what works. What threw me off is that most 990's use a flywheel with out teeth. I think yours is the first one I have seen with this set up. Maybe there was a certain year Briggs and Stratton went with a geared starter over the starter-generator.

Arob, the manuals and data on these are sketchy at best sometimes.

Though I have seen a 1978 (engine was a 78 anyway) with the c-clip front wheels, the 1978 manual lists a front wheel hub. At the same time, it lists only a starter/generator engine.

We don't see the starter plus c-clip wheels until 1980 according to what I could find in the manuals. Looks like you are missing your heat shields, BTW.

Hmmm it could be a different motor, it has the pto hook up in the front but has no pulley on it, there's threads on the shaft where one could be put on , but i'm not sure , im just going by what the fellow before me , had told me ,

Are starter- generator's easy to find ? if so it would be so much much convenient, because the starter that's on there now has a plastic nut thing which turns the fly wheel not sure what its called, i have to replace every month cause it just strips it

Starter-generator's are some what easy to find. The only problem with the starter-generator is that you need 990 specific start-gen brackets. Also your engine has to have the large diameter pulley on the front for the start-gen belt. From what I can see in the pictures your engine does not have this pulley. This pulley can be found on just about all B&S engines from this era. Many garden tractors used this set up.

You would have to get a used starter-gen but they make rebuild kits for them. These starter-gens are easy to rebuild. I can get you a picture of what the pulley looks like tomorrow and the starter-gen.

My 1980 Farm King has c-clip front wheels and just the starter. It appears to have a stator behind the flywheel for charging, and it is original.

I also see in your pics that it looks like you have the bolt on steering wheel instead of the one thats held on with a roll pin, It also looks like you have a chrome air filter cover, these are a couple of changes that were made around 1980.
