After more than a year working on our project I finally tried to start it today - with no luck. Installed ovhl carb, new harness & plugs, ovhl Bendix SF4 mags, new fuel hoses and refurbed the gascolator - actually a fuel strainer.
Tried hand propping today until I gave up, didn't seem to get a spark or in the least bit interested in starting. My real question is on the hand-propping, not sure how much prop it takes to start this thing...
I have enough compression that with a full hard swing of the prop - it stops after about a third of a rotation??? It seems in my limited experience with continentals that I got quite a bit more arc out of a swing but its been a while. I start this one in about a 10 o'clock position and it stops by 6'oclock usually with a slight rock back. Trying to figure if this is normal? I'm no light weight (210 lbs) but that's all the rotation I get out of a swing putting everything in it trying to get as much prop speed as I can get - which isn't much.
So is this normal? I'll start trying to verify mag timing and spark when I get back to the airport this week also. By the way, there are 4 hash marks on my prop flange about an inch from the TDC mark. The last and furthest one away from TDC has a dimple put in it with a small needle punch. I did all my mag timing off of this mark as all the numbers around the hash marks (lines) are long gone and I assumed this one was marked as the one to use by someone through the years. Does anyone know what degree each mark actually represents?
