What timing do i use?

[xtreme_karts]

I have a genuine honda gx200 and have the Long billet rod 3.313 (.10inch longer) and was wandering if i still use the 8 degree advance? Or would this be less due to the size of the rod?

On one of the engine i will be using a honda aluminium flywheel so i take it that would need a 4 degree?

Also im going to try the engine without the headgasket and seal it this sealer, Has anybody used this before?

Try it as is, if it pings then retard the timing.

As for eliminating the head gasket, look here.

Your compression ratio is going to be ridiculous, I hope your going to run this thing on some nice fuel. There is such a thing as to much compression.

Welcome to the forum.

Are you sure you don't mean advance the timing?

You say if it "pings" do that mean backfires from exhaust?

Thanks for the post

No, retard the timing as in less degrees of advance. By pings I mean detonates, as the engine runs it will go pink, pink, pink, pink, pink ect. That's really bad, don't run your engine if it does that. That will be caused by having to high compression and/or timing advanced to far.

It'l do it more whilst under load and when warm so listen carefully when you first take your kart for a serious drive. Sometimes you can barely hear it, other times it will be very clear.

Also referred to as a knock sometimes. Higher compression is going to heat the gas before the spark plug detonates it. Use a high octane gas.

If your going with that rod mod it'd be worth your while spend some time researching here: http://arcracing.blogspot.com/
There's good info you should know in all those pages but I'm pretty sure one of they're blogs has a good writeup about using that rod.

Dont run an advance key with that flywheel. The Honda aluminum one has 4 degrees advance already built into it. You shouldn't have to go 8 degrees until you are into cams and carb work.
