how do i set my timing.

It is a 62t/61x setup ported cases and cylinders and a lightned flywheel. i am in the assembling stage and have never assembled this assembly before. i have searched and will continue to search but figured someone might chime in with a quick answer. i am wanting to advance it 3* and i am running a ADA with 35cc domes. thanks.

also the flywheel and stator came out of a 6m6 so can i still use the marks on the cases and sator to set my timing? or since they are different setups would this matter?

pull your flywheel cover, their should be marks on the flywheel itself. each indicating a degree. its as simple as turning the flywheel to the pre-marked degree wheel and bolt it on their tight.

What compression are you at currently?

i am mostly concerned about the fluwheel mark and case mark are from two different setups. and i dont know if they are all the same? o yeah and there is one one mark on each i think i can eyeball it with a ruler and get close to 3mm though.

Im posting some pics in about 10 minutes of my setup ( i tore it down today)

you can get an idea how to line up the stator plate with the marks on the case.

Just line them up @ the stock mark in the cases w/the line on stator plate, then check with a timing light when engine is running.
To do this, remove coupler cover, make a coat hanger pointer to mount off the cover stand and over to engine side coupler, next remove sparkplug and install a dial indicator set to a spec height for the *21 degrees (STOCK) or *24 if you want *3 degrees more advanced timing, make a line on coupler for pointer, then hook up a strobe timing light and start and rev to 5000 rpms and see if your pointer marks line up, If they don't, then move stator plate until they do.

:scratchchin: Stupid question, but what's the specific height of a dial indicator at 21 degrees and wouldn't this change with different size stroke engines and piston compression heights?

I think it would be a lot easier if you had one of those timing lights that are 2-stroke compatible with the adjustable advance feature and just mark the coupler at TDC.

Well I have a Moroso huge degree wheel and have made my own timing charts for all different combination of strokes, rod lengths, and piston heights.

Degree Wheel, Steel, Blue, 18 in. Diameter

Measure timing functions accurately.
These Moroso Pro degree wheels are designed for the professional engine builder. They accurately measure camshaft centerline, valve timing, TDC, and BDC. Made from heavy-gauge metal with a silkscreen finish for long-lasting use, they include an adapter to fit virtually any engine.

I don't have my charts with me @ home....PM me if you need a specific degree height of a piston, stroke and rod combo.
