TORO TECH:
THERE ARE STILL A FEW THINGS THAT THE COMUNITY CAN HELP WITH.
WHAT MM CARB THROAT IS WORKIN FOR YOU?
ANYONE ELSE FIND THESE MAGS HAVE 10 DEGREES OF TIMING BUILT IN?
HOW MUCH MORE CAN WE GO ON THE PORT TIMING?
.025 COMPRESSION HEADSPACE
98 ATC EX PORT
108 IN. PISTON SKIRT
58 TRANSFER PORTS ALL 4 SAME TIMING
PISTON SKIRT ON TRANSFER SIDE RAISED .100 FOR A RPM INCREASE OF ONLY 400RPM. THE BIG RPM CHANGE WAS THE TRANSFER PORT CHANGE FROM 41 TO 58 DEGREES.
I DONT WANT TO BORE YOU GUYS THAT ARE HIGH TECH INTO ENGINES NUTS AND BOLTS BUT LET ME TECH SOME OF YOU ON HOW TO CHECK THE IGNITION TIMING WHILE RUNNING!?
FIRST YOU NEED TO FIND TDC
USE A PIECE OF 1/8 SOLDIER WIRE BENT 90 DEGEREES AND INSERTED INTO THE SPARK PLUG HOLE.
TURN THE ENGINE C.W UNTIL IT STOPS, PUT A PIECE OF TAPE ON THE FLYWHEEL UNDER THE COIL MAGNET PICKUP ABOUT 2 INCHES LONG WITH THE 2IN. PART HANGIN OUT TO THE LEFT OR CCW DIRECTION. (OR JUST MAGIC MARKER THE FLYWHEEL ITS EASIER)
NOW HOLD THE SOLDIER IN THE SAME PLACE IN THE PLUG HOLE AS BEST YOU CAN AND TURN THE FLYWHEEL CCW UNTIL IT STOPS AND MAKE ANOTHER MARK UNDER THE COIL ON FLYWHEEEL OR TAPE.
NOW PUT A MARK IN THE CENTER OF THOSE 2 MARKS A CLOSE AS YOU CAN AND THIS IS TDC.
NOW FROM THE TDC MARK WHICH SHOULD BE RITE UNDER THE STATIONARY COIL PICKUP WHICH WILL BE YOUR TIMING MARK POINTER, MEASURE 5/16 TO THE LEFT OR CCW. DIRECTION AND MARK THE FLYWHEEL THERE. THIS IS 10 DEGREES ADVANCED
NOW DO THE SAME THING 2 MORE TIMES WHICH WILL BE 20 AND 30 DEGREES ADVANCED.
NOW GET ANY OLD KIND OF STROBE TIMING LITE (WE ALL HAVE 1 FROM OUR HOTRODING DAYS) OR BUY 1 AT A GARAGE SALE FOR CHEAP BECAUSE NOBODY USES THEM ANYMORE.
IM OUT OF SPACE ILL DO ANOTHER POST TO FINISH
