Started my sled

[tator]

Might be a stupid question, but might you have fouled one spark plug?

ya, was wondering if it was running on all cylinders. hopefully nothing major like yamadogs.

I need to check all that. I have not ran mine hard enough to cause engine issues IMO. Gems, air fuel spot on boost gauge. Only run high octane pump fuel with boost additive.

Fuel was in sled for about a month before noticing it on a trip to munising. Same fuel still in it yes with stabilizer. What is the iacv?
