1  Mower Building / Setup Help / Chassis / Re: 1 off Chassis building jig ideas??? on: January 28, 2015, 09:01:41 PM
The problem I see with your idea, is that here in the states, any thickness of plywood will have some crown or be warped as it is taken off the stack.   It is only flattened when nailed or screwed to a frame that is straight and strong enough to hold it.  Another issue would be from the heat transfer during welding which could ignite the plywood.  Do you have a concrete floor level enough to lay it on?  Maybe a thinner piece of sheet metal on the floor to tack the frame to?  This would be a lot of stooping and working from your knees, but less cost possibly.

The jack shaft turns the same rate on each end.  You have already figured that half of the ratio when you get the engine to jack shaft.  When you then multiply by the secondary ratio, you get the final drive.  You can always check you figures by engaging the clutch and turn the flywheel, counting the revolutions, until the rear tire has completed one exact revolution.

Just because the jack shaft has two different sized sprockets or pulleys, doesn't mean they turn different speeds.  The ratio is calculated based on the change in revolutions between the shafts.  i.e crank to jackshaft = ratio #1.   jackshaft to rear axle = ratio #2.   #1 x #2 = final drive.

Any clearer?

6  Engine Help / Briggs OHV & Vanguard / Re: 2 barrel carb inlet tube question on: January 05, 2015, 10:56:38 PM
Do you have the black spacer installed that goes between the elbow and the carb?  All of the inlet tubes I have seen are on a 45 degree angle with the throat of the carb.  With the spacer installed, you will have room to connect your fuel line.

I actually turned my elbow around as Tyler said, and used a short filter to clear the side of the hood.  I did not hone the elbow or the intake to match, just drilled and tapped the middle bolt and went with it.  I think the engine runs just fine.
8  Engine Help / Briggs OHV & Vanguard / Re: 30 cube vanny 2 barrel elbow question on: December 06, 2014, 10:54:20 PM
Yes EC sells a KN style filter to match their filter adapter, I believe it is 2" filter height, same oval diameters, call the sales desk and tell 'em ya want the short one.  Same price as the taller one if I remember right.

Grubdiggers response is true for ARMA.  Unless the rules for USLMRA change for 2015, the only mod allowed for G/P is aftermarket exhaust.  Carb and air filter are supposed to be as delivered from the factory, according to my conversations with Kerry Evans.

You might also look at the "timing marks" on the flywheel again,  I had one to spin because I didn't torque the bolts well enough.  It will act just like a sheared flywheel key.
11  Engine Help / Briggs Flathead / Re: Sp motor worth what??? on: September 30, 2014, 12:10:49 AM
It could still have the weights.  I had the eccentrics milled off of that style of crank in a 28 series, used the brass weights, and it is still running after 4 years.
12  Mower Building / Setup Help / Driveline / Re: Ap class questions??? on: September 22, 2014, 03:22:05 PM
So the answer would be to run a 6 or 7 on the engine with a 4 or 5 on the tranny.

I am glad that got cleared up.  I was wondering what color he wanted the other 1/2. lol

Drop your axle sprocket to 44 and you will have a gear ratio of 4.85   Your ratio as it sits is 5.02:1 which might be a little steep.  Race in 5th gear, your 25/25 gear set, top speed about 35 MPH depending on tire size (16") and RPM of engine (3650)
