I have a (860 Tractor 172 gas engine) I am trying to figure out why I can not get it to start. It had a blown head gasket, pulled head, had head reworked, new head gasket, good compression now (125 psi). Installed new points, condenser, replaced coil, new plugs wires solid core, new Autolite 437 plugs, have hot blue spark when tested. I rebuilt the carburetor (marvel schebler TSX-813) master kit rebuild, all new parts, float set a 1/4" and idle jet set at 1-1/2 turns out, load jet set at about the same.
The engine was running before, it had a miss, and there was water in the oil, and compression was low on #2 & #3, but it did run.
I checked to make sure my timing was correct,(Used a vacuum gauge and line off compression tester with schrador core removed, lined up dead on with mark on flywheel) found #1 was 2 terminals over, reset distributor to #1 on cap.
I am thinking my problem is within the fuel system, I think for some reason I am flooding. My plugs smelled strong of gas, and there was raw gas where the air inlet hose (Choke Section) attaches to the carburetor when I removed it. I shut off the gas valve on the tank, and removed the drain plug on the carburetor, pulled the plugs, cleaned them.
How should I try to start it tomorrow? Before I pulled the head off, I had to just bump the throttle a little, and pull the choke just a little and it would fire right up, (Even with blow head gasket and Carburetor leaking from everywhere it could)
I am new to this type of setup, I am sure it is something I am doing wrong.
Thanks for any help
