I have a chance to buy a nice 318 with a blown motor.

My question is what are my options for a replacement, try to find a used motor or would new be best, what should I expect cost wise. I'm mildly mechanically inclined so I feel I could do the instal with a little guidance from some people on here.....

The 318 is an Onan B43G, right? I had a 316 so I know a little about this.

I think you might be able to convert over to a B&S with some work. I remember a thread on that somewhere..........

I think there are "kits" you can buy to convert to Honda power, and there are guys selling Onan long and short blocks if you want to rebuild the one you have.

What do you mean by blown...as in rod through the side of the motor, engine won't start and stay running, it burns allot of oil and runs ruff?

Machines made before mid 1987 had the Onan B43G (up to s/n 420000). The 318's made thereafter, until 1992, had the P218G. The difference is point ignition vs electronic. Neither are in production any longer, though parts are available as long as you have an intact engine block (cast aluminum). If the block is bad, look on Craigslist for the occasional opportunity, though they are getting rarer and rarer. There are also Honda replacements on eBay for around $1700-1800 or something, but I understand it's not a perfectly smooth swapout. Some parts of the tractor have to be modified.

I know of a brand new P218G sitting on a dealers shelf (last time I checked). As I recall, it was going for $2200.

I don't have a bad thing to say about the P218G.

$2,200 seems a bit steep, no?

You can have a price that seems steep to 299,999,999 people in the US as long as there's the one who says, "Awesome, I'll take it!".

I agree, that amount is over my limit too. But to someone else who can't cope with losing their 318, it might be worth it.

Thanks for the input, too much money to fix so i'm gonna pass on the 318. It has a rod through the side of the block.
