1  Engine Help / Briggs Flathead / Re: OPPY TIMING QUESTION on: August 28, 2015, 07:15:49 AM
External fuel pump, yes pulse is pulled from the side of the intake. I read somewhere that the pulse fades at high rpm. I thought of running  T in the pulse line putting one line where it is on the intake, and a second one tapped into the top of the velocity stack. My only fear is losing pulse with a T. Has anyone ever tried something along these lines?

BIG AL that was my first thought. I played with gearing first, but whats leading me to timing is that Im a cannon off the corner, but flat at the end of the straight and our straights arent very long. Flat at 4000rpm. Plugs are a nice ash brown color so I believe my mixture is good. I do have a velocity stack and my carb is honed out and opened up. Lots of work to the carb. You guys are great and I know most of you have been there and done that so Im all ears!
REDLINE does it sound like a carb problem to you? I havent ruled that out either. If so Ill go that route in a heartbeat lol. What degree should the timing be?
I should most definetly be turning past 4000rpm with the work done to this mowtor.

Yes air gap as in coil to flywheel. My valve lash is set to Mikes specs.
8  Engine Help / Briggs Flathead / OPPY TIMING QUESTION on: August 26, 2015, 10:14:39 PM
Quick question.....I have a 46ci oppy with billet rods, billet flywheel, precision 212 cam, EC double valve springs, ported to the hilt. Stock appearing carb lol. I have heard and read mixed opinions in the past about where to set the timing along with air gap. Where Im set now is  air gap 15, timing is 5 marks advanced on flywheel. I run a 1/10th mile track and Im around 4000rpm. Very aggressive off the corner but flattens out at end of the straight. Like I mentioned, Im not breaking 4000. Any tips on what timing and air gap with this cam? Thanks in advance!

ARC rods your stock pistons will not work. Model 28 pistons or I believe, someone please correct me, but they might make 31avs pistons to fit an oppy stock bore. Not 100% sure on that one. But model 28s fit.

Your absolutely right! There are 4 buttons from top to bottom: max rec, power on, mem min, and mode. Now to set you press and hold max and min down until bottom number flashes. Here was my mistake....I thought the first setting was the max rpm. It is NOT.  First setting is the cylinder temp you set to alert you of temp getting hot. Using the max button as up, and min button as down, set desired temp and hit MODE. The top screen will now flash. Using same max and min buttons set desired max rpm. Keep in mind the number you see is x1000. So if you set it at 4 it is 4000rpm. Set desired rpm and press MODE again. Bottom number will flash. This is calibration mode. My 46ci opposed twin I set at .5.  (YOU WILL HAVE TO PLAY WITH DIFFERENT CALIBRATION SETTINGS FOR DIFFERENT ENGINES) After setting this press MODE again and then hit the tiny red button on the right side of the tach. This is the STORE  button. This stores your settings. NOTE: ENGINE MUST BE OFF TO SET YOUR SETTINGS!. After pressing the STORE button, start your engine and your in business!!

I have an old Digatron I used on my nephews race kart. I mounted it on my race mower and Im having trouble calibrating it. The motor is a 46 opposed twin with a precision cam. Everytime I set the calibration (be it .5, 1, or 2) it reads around 2.40. Looking at the front of the motor, the wire is attatched to the left plug wire. I even have about 3" of the green wire taped to the plug wire, and it starts about 2" from the boot. Am I missing something with setting it? Any help is GREATLY appreciated. Thank you!!

Does anyone have the link to Roosters post on oiling mods? I found it once last year and now I cant. Been typing different things in the search bar but just not coming across it. A link would be great. Thank you!
