    The redneck method:

    Bring your CEN piston to "true" TDC. (using a dial indicator to verify)

    Then take a new pencil or dowel rod and drop it down the MAG spark plug hole. Mark the pencil with a razor blade laying flat across the head.

    Now drop the pencil/dowel rod down the PTO plug hole and mark it.

    The marks should be identicalm or within a couple thousandths of each other.


    PROPER method is to use a dial indicator and degree wheel.

    Using the dial indicator, find "true" TDC of each piston and mark it on the degree wheel placed over the engine coupler.

    Each cyl should measure exactly 120* degrees apart.



    What diaphragms do you speak of?

    Yes, put a fuel pressure gauge between the fuel pump and carb. Should read around 1-2 psi at idle and 4-6 psi at WOT.

    did the pencil test.. they were perfrect there.. fuel pump is fine. where is the engine coupler and do i have to add a degree wheel to check like you said?

    Coupler is under the plastic cover on the back of the engine. To properly check your crank index, you need the deree wheel. But if the pencil method checked out, you are prob good.

    What was your fuel pressures?

    Have you checked the fuel tank for debris?

    Have you checked/replaced the fuel hoses?

    Have you tried bypassing the petcock?

    Did you go through the carbs?

    Have you checked your carb settings to the manual specs?

    That piston failed from a fuel issue or timing is too advanced.

    Was there any work done to the elec stator?

    Does the engine race on it's own when idling?

    fuels prseeues were fine. all hoses replace carbs adjusted and cleaned, fuel tanks clean, getting plenty of gas. the engine does change idle a little when idling.. only running 2 cylinders and sometimes i see a flame in the carb of cylinder thats not running. how do i inspect and check timing?

    Did you inspect your reeds?

    Need to get your hands on a manual for timing check procedure.

    i looked at the reeds.. they look fine..how do you check them? what do i look for?

    also.. how much ft lbs do i tighten the cylinder nuts and then the head nuts to?

    You inspect the reeds for cracks, chips, and excessive gaps in the petals.

    If you're seeing a flame at the bottom of the carb, you have to have a faulty reed in that cyl, an ignition timing issue, or a crank that's out of phase. (index)

    Do you see alot of fuel spitting out the carb at idle?


    Head nuts 18 ft lbs.

    Cyl base nuts 28 ft lbs
