Triple timing

[Mixedangased]

Right I’ve been trying to check the timing on my h1E put it to ted on left piston with dial gauge rotated crank 2.94mm to check the timing mark and had to bend the pointer to align,gapped and checked the lower pick up alignment to the rotor .question this times the left cyl what about the centre and right ? As what crank setting is the north pickup aligned ? I put a timing light on the left side and was pretty much spot on at 4000 rpm but the right side cyl is off ?? What am I missing or doing wrong? Surely the upper pickup should be set up to something as well and how come we have three cylinders and only 2 pick up ?? The right cylinder is allways misfiring and plug is allways wet, carb have been gone through and rejected new float valves etc gen,new cdi,coils rotor brushes ,plugs leads caps etc,running higgspeeds,just seems misfiring mid range top end is fine and on song,been on a dyno so know the mixture is spot on through the range.at a loss now ????

Both pickups work in parallel to trigger the spark. I assume that at the time, they struggled to generate enough juice with one small pickup so doubled them up. They are triggered each time the rotor projections pass, so every 120 degrees. It's not like say a KH400 where one projection on the flywheel passes 3 different pickups. This is 3 projections passing one (in effect) pickup. Confusing, granted, but think of it as one single pickup. As the rotor is a precision part, if one cylinder is correctly timed, they all should be. This assumes that your crank is correctly phased of course, which 99.9% of the time they are.

Looked at Glenn’s manual ,even more confused now a pics showing h1 d has 3 pickup coils mine has 2 so do I set the timing at 2.94mm or 3.45mm? . .when I first looked at it the pointer was miles out at the 2.94 setting so will check what it’s like a 3.45 and try that .thanks for all the help

I think that you are looking at page 199 of the PDF and not page 199 of the manual. Go on a bit further and look at the actual page numbers.

Ah ok will have another look thanks

So you lined the Pinter up with the cut out on the rotor?
Then checked the alignment of the SG rotor with the marks on the pick ups
Checked it with a strobe.
The SG rotor you lined up has 3 points one for each cylinder, so if one lines up the other 2 will automatically line up there is no adjustment per cylinder
Hope this helps

You may find setting timing at 3.45 (early H1 setting) will offer better performance than spec 2.94 setting.
Setting timing via LH cyl will set it for all cyls. The only way cyl timing will differ between setting is if the crank is not properly assembled.
In any case the small timing difference that may exist will not cause the problem you are experiencing.... timing is not your problem.
Spark is generated from the same source for all cylinders. The only difference between cyls is coil, wiring to plug, plug, and brush connection at rotor.
I'd suggest swapping RH & Ctr carbs to see if problem follows carb.
