Help!! Weak or intermittent spark?

[Roz]

New to this sight but need help.  Was wondering if anyone has a way other than swapping parts to check for intermitten or weak spark?   Have 135 psi compression and everything else obvious checks out but won't start without starting fluid and left side exhaust is cold

Yep. OHM meter and visual checks. Check the pilot jets and make sure the float bowls are on the right carbs

remove spark plug, place penis in spark plug hole, then kick over

Could be pilot jet size

Get inline spark testers. Ohm out caps, coil, stator , check pickup gap, sync carbs with vacuum gauge . It could very well need more fuel or idle circuits could be clogged, they are a needle sized hole
