Better do a seal test.
Start it up and spray some starting fluid behind the clutch [at the crank stub] and if it revs up, you have a bad seal.

I sprayed some starter fluid as you suggested and the revs stayed the same, should I take it for a spin with different plugs?

Take it for a spin with NEW plugs. Also make sure the plug cap has clean contacts and the wire is tight onto the coil.

OK i just took it for another spin and same thing with the plugs, one fouled and one clean. It seems to run fine, but one thing i noticed was a sound kinda like sucking air that I'm pretty sure wasn't there before.

Crank seal could be sucking air making that cylinder run lean

I noticed there seems to be abit of sludge leaking from my exhaust gaskets, could an air leak there cause issues like this? Also what about a blown head gasket?
Thanks!

Re: Engine bog

I also had some sludge coming out of my gaskets. I resealed them with high heat gasket silicone and REPLACED THE PLUGS!! It wasnt burning everything and was letting fuel/oil into the exaust

OK i got the sled going well (finally), replaced intake and exhaust gaskets then i tried running it without the air box again... Turns out the airbox was clogging it up abit Has way more power and no bogging
Now i have a question regarding the temps the engine should run at. It has 2 rings that fit under the spark plugs to get the temps. I've had it read as high as 500f when i was pushing it, is that alright or too high?

Head temp gauge!
That's about right, watch and see where it stays most of the time and if it starts climbing out of that range it's time for a cool down.
