The Multi-Fuel Timing Conversion Kit Installation & Setup Instructions 1. Remove the flywheel shroud from engine, uninstall the recoil pull start unit from the shroud. 2. Remove the valve cover and the spark plug. 3. Rotate the flywheel so that the intake and exhaust valves are both closed. This is 360 degrees in the 720 degree cycle of the four stroke engine. 4. To find piston TDC, you will need a degree wheel attached to your crankshaft, a degree-wheel pointer, and a piston stop. Install the degree wheel on the nose of the crankshaft and position your pointer- often just a piece of wire-over the degree wheel, as close as possible without touching it. Your piston stop can thread into the holes or simply be a strap that pulls over the deck of the block. It doesn't matter as long as spark plug it keeps the piston from reaching TDC. 5. Slowly spin the crank clockwise until the top of the piston contacts the piston stop, and check the position of the pointer on the degree wheel. Count up from the zero mark on the wheel and make note of it. Now, slowly spin the crank counter-clockwise until the piston makes contact with the piston stop again. And once again, make note of the degrees on the degree wheel in the direction closest from the zero mark. In other words, both of your readings should be less than 180 degrees. Now, find the average of those two numbers. For example, if your readings were 36.75 in the clockwise direction and 35.25 when turning the crankshaft counterclockwise, the average is 36 degrees. 6. With the engine at TDC, paint a vertical white line on the flywheel from center crank shaft to the upper fins of the flywheel. This can be used later to verify the the timing with a timing light. 7. With the cylinder at TDC, mark the flywheel and the engine to establish a TDC reference. 8. With the flywheel shroud removed from the engine, set a square up off the mounting base of the engine with the flat side of the square facing the
motor. With engine set at TDC, mark a vertical line at the center of the crank shaft, holding the square steady rotate the flywheel 180 degrees to ensure the line you made is centered on the end of the crank shaft. This needs to be Spot on center. 9. Drill out the center hole in the end of the crank shaft with a (3/16 ) drill bit to a depth of 3/8. 10. Utilizing the center line you marked on the end of the crank shaft, cut a 1/8 deep vertical slot in to the end of the crank shaft. Make sure you start on the line you marked, cut to your depth, then grind out from the center on equal sides so that the pin fits snug and is centered into the end of the crank shaft. 11. Next bevel the hole in the end of the crank shaft so the Multi-Fuel Timing Conversion Kit (MFTCK-100) center shaft with the cross pin fits hole and the cross pin fits securely in to the slot that has been cut earlier (step 9) in to the end of the crank shaft. The center shaft with the pin attached to the 20 tooth gear must be centered with the crank shaft hole and pin slot. 12. IMPORTANT NOTE: At this point, if you have made a mistake, you can adjust (shorten) the standoffs that attaches the MFTCK-100 plate to the flywheel shroud, this will allow the MFTCK-100 plate to be drawn in towards the engine. Now you can grind down the end of the crank shaft and repeat step 8 thru 10 again. 13. You can now remove the existing ignition (coil and wiring) system from the engine and tape off any exposed wire leads that you have disconnected. 14. Reinstall the flywheel shroud. At this point you will need to determine where to drill the mounting holes in the MFTCK-100 plate that match the existing mounting holes on the shroud from the uninstalled recoil pull start or make new ones (depending on your engine). Insert the MFTCK-100 thru the opening in the shroud and seat the 1 gear shaft with the pin into the slot you cut into the end of the crank shaft. Once the MFTCK-100 is firmly inserted into the end of the crank shaft, rotate the MFTCK-100 to the desired position and transpose the hole from the flywheel shroud to the MFTCK-100. Center punch the marks you just made and drill them out. 15. INSTALLING THE MAGNETIC PICK-UP HALL SENSOR & MAGNET - Before installing the MFTCK-100 on the flywheel shroud. Remove the retaining
clip from the 2 gear shaft and remove. Remove the Hall sensor holder bracket. Pull the bracket and sensor holder out of the hole and install the Hall sensor from the MSD 41510 Kit on to the sensor holder (screws included). (Once you have the MSD 41510 wired to the engine and powered up, you can pass the magnet over the sensor and watch for the led to flash, the magnets north side with trip the sensor and the south side will not). Utilizing JB Weld Recommended, Epoxy the magnet that came with the MSD 41510 kit (north side of the magnet facing out from the 2 gear) and install the magnet in the hole provided on back side of the 2 gear. Before reinstalling the 2 gear, make sure the pin installed on the end of the 1 gear is in a vertical position. With the magnet facing the plate (away from engine) reinstall the 2 gear with the small hole on the backside of the gear in a horizontally position to the outside, so it lines up horizontally with the two gear shafts. Make sure the gear shafts and the hole in the 2 gear are lined up horizontally. Now reinstall the bracket and sensor holder, brass shim and retainer clip. Set the timing on the MFTCK- 100 to 0 and tighten the set screw on the end of the sensor holder to lock the gear shaft in place. 16. Before removing the shroud from the engine. Level out the MFTCK-100 so that it is at equal distance from the shroud all the way around, then measure the distance from the front of the flywheel shroud to the back of the MFTCK-100 plate, this is the length that the standoffs (included) need to be cut to. Remove the flywheel shroud from engine and install the MFTCK-100 utilizing the new holes you drilled into the fly wheel shroud and or the MFTCK-100 plate, depending on the engine you are installing the MFTCK-100 on. Insert the screws (included) thru the holes in the MFTCK-100, install standoffs on screws and bolt the MFTCK-100 to the existing or new holes (depending on you engine) in the shroud. Reinstall the flywheel shroud securely on to the engine. Make sure the center shaft and pin fits properly into the slot you have cut into end of the crank shaft. 17. ADJUSTING THE TIMING Rotating the Hall sensor clockwise RETARDS the timing, rotating the Hall sensor counter-clockwise ADVANCES the timing. If you set the engine at TDC = 0 mark on the timing marks on the timing plate, you get about 35 deg. advance and 35 deg. Retarded. So if you wanted the timing to be at 45 deg. ATDC, you would need to set the engine at TDC and set the timing on the MFTCK-100 to 10 deg. when first installed. At this point you can verify your timing with a timing light by shining the timing light thru the MFTCK-100 to view the white line that you painted on the flywheel earlier in step 6.. If you installed everything properly, the timing marks on the flywheel and MFTCK-100 will coincide, the white line should be in the vertical position and the timing on the
MFTCK-100 should be at 0 deg.. If the white timing line painted earlier on the flywheel does not coincide with the timing marks on the MFTCK-100 you will need to re adjust the gears on the back of the MFTCK-100 as was done in (step 14) to match the 0 deg. timing marks on both the flywheel and the MFTCK-100 timing marks. For fine adjustments un tighten the set screw on the 1 gear and rotate the 1 gear to the desired position and re tighten the set screw on the 1 gear. Recheck with a timing light. This will allow you to make fine adjustments in the timing as needed to obtain a true 0 degrees. 18.
