Default Os Cvx12

I have a problem here. i can start it easy. but once the glow warmer is away from the plug, it stops.

could it be the cod rod problem? or i have change another plug, still the case.

Sounds like its rich. Have you tried idleing it up or leaning the LS needle?

now, it is running ok, the temp is only 80-90. very strange.

Hi Franky,
When you are tuning your OS are you winding the mixture screws in then counting the turns out?
If so incorrect,they need to be level with the screw holders then you wind them in.
My favourite hopups are,cen head,A5 os plug and flowing the manifold+ internal work.

it depends on your car or truck, two speed or no two speed and gearing, these are all factors that will effect your speed.

Maybe so but rear and side exhaust motor's are two different things......
Nice feeling when you run a cvx against a cvr and other side exhaust tourer's and pass them on the main straight......
