GX670 24hp worth saving???

[DaCajun]

I was able to pickup a GX670 over the weekend for $50. The problem is it had a dead cylinder. Well I pulled it a part and it threw a rod. It's going to need and new crank and a set of rods. So I looked up all the parts to rebuild it; crank, rods, pistons w/ rings along with gasket and seals. It looks like the parts will be just under $700, my question is, is this motor worth the investment? I do have a very clean and nice Vanguard 18hp in my possession. Which is the better motor between the two. I personally think the 18hp Vanguard appears to be a better motor. I have a Yamaha 36 volt cart that I'm putting together the stuff to do a big block conversation. All ya'lls help is much appreciated.

BTW, here's a few pics of the 18hp Vanguard and rearend I've collected.











Thanks,
Dave

if it were me id rebuild it you should search the internet and try to find use parts crank rod etc. If not drop it by and i'll get you your 50$ back

I think you should send it to me If you have the skills to rebuild, add a rev kit and timng advance key while your at it and for less than $900.00 you have a great motor. I think it's worth it

Is the GX670 better than the Vanguard?

[essness]

I dont know that I would say that. There is a lot more after market parts available for the Vangaurd than the Honda.
I'm partial to the Honda's only cause, I have one

With that being said, should I be able modify the 18hp vanguard to somewhere in the low 20hp range?

I'm kinda hoping some of the smart guys will come along but as I understand it, gaining 2 hp should be very easy with the briggs.

yeah, put a free flow breather/exhaust on and re-jet it, that should be good for 3 or 4 hp. Not enough.... get a cam an rev kit.

toss the honda out back and wait till you get a bunch of them, then you may have enough parts to put one together. as it stands you'll probably end up spending as much in new parts as a new one costs.

for the 18hp -add a two barrel carb and intake and get 2 hp right away. add rev kit, header, rejet carb, timing advance and should be at 25-28

Yea I was thinking of using the two barrel carb off of the 24hp honda along with maybe a cam and for sure a rev kit. All tho the 24hp is a bit bigger in cubes. Heck I can always build it latter on. Or should I sell the 18hp Vanguard to fund the honda build? Or, looking at the BIG picture with the Vanguard I have more options with all the aftermaket parts that are available? Decisions, decisions, decisions!!!!
