ARC Billet flywheel

[brookbank85]

I am in the process of adding a 6626 ARC Billet flywheel to my hemi predator 212. But when installed I can't get go kart to start up. Started off by pull rope breaking from compression and adjusted valve lash to help with that. And there is spark I pulled and checked. It just doesn't do anything. Anyone have a clue to what it could be?

Did it run immediately before you installed the flywheel? What I am asking is, did you do any other modifications at the same time?
Is your flywheel key installed and flywheel torqued?
My guess based on what you have already posted is that you have a timing problem.

 

[brookbank85]

Yes it was using with stock flywheel before and it ran. The flywheel finally came in and I put on. Flywheel key is installed and good and it is torqued.

ARC website says that wheel has 32 degrees of timing advance.
I think the original timing was 24 degrees.
Have you changed anything else, or is it all stock? (Camshaft especially?)

 

[brookbank85]

everything is upgraded flywheel was the missing piece I had to wait on but drove it easy until I got a flywheel

how did the valve lash change by installing a flywheel?

 

[brookbank85]

I didn’t but I checked it to verify .003 intake and exhaust

Airgap should be bigger between newer coil and flywheel.

 

[sparkwizard]

Minimum gap .030

 

[ole4]

so after fixing the broken starter which you say broke from compression was it still hard to pull? You said you checked the .003 lash and it was OK so you did not adjust anything but now it pulls over ok but no start is that a correct statement?

Coil gap?

 

[sparkwizard]

He stated he does have spark.

Was your spark at the plug gap, or in a spark tester?

 

[JimN]

I would put in new spark plug just to take that out of the equation and if it still doesn't start after a few pulls either, put the old flywheel back on and test or retard the new one about 4*. With the minimum coil gap required for either one.
He doesn't mention if he verified his actual timing.
