1  Engine Help / Briggs Flathead / Re: 10.5 hp carb question. on: June 12, 2014, 07:56:37 PM
Thanks rooster. I don't have my machine here with me to just go and get the numbers off it. (long story). After lots of digging and a couple calls i finally found the right numbers and then, looked up the parts mnual. Sure enough my carb is stock with that engine. I race in central ontario with a club called grass hogs.
2  Engine Help / Briggs Flathead / 10.5 hp carb question. on: June 10, 2014, 09:08:29 PM
How do i determine that the walbro carb on my 10.5 hp is the stock carb that came  from the factory? The class im racing is telling me it is not and i have to run the 1 piece flowjet. The rules state i must use the stock carb. I am certain it is the stock carb, i just cant prove it. Any ideas would be appreciated. Thanks.

Cyclone is right, read read read, if this is your first build it will not be as easy as it sounds, but don't get discouraged, it's alot of trial and error until u find the right formulas for pulley ratios, belt guides, clutches etc. And most of all build what YOU like. Figure out if you might actually want to race with a club, (its safer) talk to that club and build to their rules the first time. It saves having to go back and redo stuff later. Use good quality parts and u will end up with a better machine. U can use things like hydraulic disc brakes and stuff from those little Chinese fourwheelers etc. to save a couple buks here and there, its not cheap its just less expensive. Lol.

Of course finishd is a relative word as you. Have never really "finished" one yet. Lol.
5  General / Coffee Shop / How long to build on: May 25, 2014, 09:18:37 AM
Ok every1, heres the question. How fast do u think that u could build a competitive machine for a stock class using stock parts with budget of about 100 buks. U have a welder and a fairly equipd shop. Im on my third tractor and my average i figure would b about 40 hours start to finish. Thats including freeing siezed wheels and axle widening etc. With a crappy paint job lol.
6  Engine Help / Honda and Clone Engines / Re: Gxv 390 flywheel on: April 07, 2014, 06:40:03 PM
Got back to the flywheel thing again today and as I mentioned earlier the ring gears are NOT the same. I thought they may be the same inside diameter and I wud just be able to transfer one from the other but that is not possible because the diameters are different. weird. dunno
7  Engine Help / Honda and Clone Engines / Re: Gxv 390 flywheel on: April 05, 2014, 05:56:58 PM
Okay,  I have an answer now. I took a stock flywheel from a gx 340 generator and set it on my gxv. It fits fine. BUT, the ring gear is NOT the same. So I wud have to say that yes the arc big block flywheel will fit BUT u would have to mount your original ring gear to it in order to still have electric start. I don't know if that's possible but I'm sure arc could answer that question.
8  Engine Help / Honda and Clone Engines / Gx 340/390 valve springs. on: March 29, 2014, 06:07:59 PM
Hi all. Just throwing it out to any1 who is upgrading the valve train on 340s, the installed height of each valve spring are not the same. The intake valve height is about .060" taller than the exhaust valve due to the casting of the spring seat in the head being that much lower and the use of a stock shim on the exhaust side.  So if your looking into valve springs keep in mind u will need about .060" of shim for the intake side so they are both set at the same seat pressures. Can any1 tell me if the same is true for gx 390s?
9  Mower Building / Setup Help / Chassis / Re: help with spindles on: March 17, 2014, 07:54:35 PM
I'm not sure what's negative and positive but I found out the hard way u must lay your spindles back. I went with 10 degrees on both sides with great results. I set my my camber so the tops of my wheels were laying in toward the mower. IMO this helps put the center of the tread on the ground when going hard in the corner with low airpressure. Low airpressure causes the tire to try to roll off the rim thus moving the outside tire tread to the middle. I run bigger front tires at a lower pressure to soak up some of the bumps cause I'm getting old. The camber is not the important and your choice, but u will not be able to steer without the caster angles. There are sum great write ups for these angles and more on this forum. Read them then read them again,lol

Thanks alot to all of u. This site rocks. I currently have a pull starter on it right now and thats all i wud use anyway so looks like i should b in good shape. Cheers

Ohhh ok. Ddnt know that. Thanx.

Perhaps he will catch wind of this post and add his knowledge or Mabey I cud send him a message direct? O ya since I'm chatting with you any way I should ask u if u have seen any reason y I can't get shipping rates from ec to Canada. I tried to order the 700 trans input shafts bushing the other night but got held up in shipping.
13  Engine Help / Honda and Clone Engines / Re: Gxv 390 flywheel on: February 23, 2014, 07:17:31 AM
I certainly will. I've read a few old posts from here that are the opposite of each other. Lol. 1 says yes they will fit as well as the valve train and reciprocal assembly, and the other says the crank tapers are different. I believe their names were Chuck and Ferris?
14  Engine Help / Honda and Clone Engines / Gxv 390 flywheel on: February 22, 2014, 06:53:10 PM
After much research and hours scouring part numbers, I still can't find a definite answer whether the billet gx390 flywheel will fit the gxv 390 vertical. Anyone know for sure from experience before I buy 1? Any info would be appreciated. Thanks. confused
15  Mower Building / Setup Help / Chassis / Re: bell crank style steering on: March 19, 2013, 05:09:34 PM
