Hoping to get some opinions on the accuracy/reliability of using a simple TDC timing tool such as this one: https://www.ebay.com/itm/Bultaco-Os...e=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649
I installed a powerdynamo ignition on my '92 360, the timing procedure is relatively simple: mount stator plate, set piston to correct position (1mm/.040" BTDC in this case), align magneto timing mark with stator timing mark, hold flywheel and torque. I used a very rudimentary method to set the timing consisting of inserting a wooden dowel down plug hole, mark TDC with razor, measure up 1mm from TDC and make another mark.
It got the job done for all intents and purposes, bike starts easily and runs pretty well. Although I'm hesitant to really hammer on it because I'm skeptical of how accurate my timing method was. Inspecting the plug reveals an asymmetrical ignition pattern (uneven light brown only partially coloring plug), an indication of detonation/pinging perhaps? As mentioned the bike seems to run well to me, perhaps my ear is not trained well enough to identify detonation?
I surmise using a dial indicator to set the piston position then somehow holding the piston in place would be the ideal method to set timing. Problem is that there is no room for a dial indicator with the motor in place, at least not any that I have attempted to use. My question is: What tool(s) do you folks recommend I use to reliably set my timing with the motor in frame? Also: Anyone in close proximity to Asheville, NC with experience in this matter who's willing to barter their assistance/knowledge for beer/food/gas money would be more than welcome...ha!
