"Champion makes a lot of diffe

"Champion makes a lot of different type spark plugs.

You should be using Champion QL77JC4 plugs, gapped at .040 . Mixture should be 50/1 (1pt 50/1 oil to 6gal gas).

Compression psi on all cyls = ??

Spark jump a 7/16" gap with strong blue fire ??"
 
"I believe you may have got so

"I believe you may have got some 'crap' from the work shop!

Read what Joe states above:
Champion QL77JC4!!!!!!
If those plugs gets 'crapped', you most likely have other problems.
Temp? (Thermostats)
Over fueling/oiling? (carbs and VRO)
Not reaching correct rpm at max? (propeller)
It may be more, but let us start with this."
 
"'So how many ounces per g

"'So how many ounces per gallon would that be'

LOL - I love the metric system, makes things easier!

'I have been putting 1quart fir 12gallons if gas is that to. Much'
That makes it about right.
If not mistaken -recalculated - it is 0.95 Liter oil to about 45,43 liters of fuel.
Slightly over-oiling."
 
50/1 = 1 pint to 6 gallons

50/1 = 1 pint to 6 gallons

1 pint = 16 ounces

16 ounces divided by 6 gallons = 2.66666666 ounces per gallon
 
"Joe:
How does you calculate

"Joe:
How does you calculate (mathematically) x% oil/fuel mix in 'your' system?
What does the formula look like?
