This is for the Experts to diagnose. I brought a 184 Lo-Boy home last night to work on for a fella. He seemed to be pretty knowledgable when I asked him things he's done to it. Anyways, it won't start and hasn't started for nearly a year. It's been setting in his barn. He used to mow grass with it and states: I could mow for nearly an hour, then it would just up and die and wouldn't start till a few days later, then mow again for awhile then die again and no start. I brought it home to trouble shoot it. Now it has me scratching my head after 4 hours of tinkering with it.
1) It has great compression on all 4's, nearly 120psi.
2) I installed new plugs
3) Changed condensor
4) filed and set points
5) checked and rechecked timing. no 1 on compression TDC mark aligned on the pulley
6) I found alittle play in the dist shaft at the point end, thinking maybe it was causing the gap to fluxuate. I installed the whole dist out of the trencher Cub(also 12 volts). No Go, still won't start
7) switched carbs, installed the carb off the trencher Cub that runs perfect, still nothing
switched caps and wires and rotor, still no start.
9) checked firing order 1,3,4,2 clockwise rotation for dist setup.
10) plenty of gas flowing through the sediment bowl and into the carb, both carbs that I tried.
When I pull the plugs, they are slightly wet. After I'm done cranking, gas runs out the carb weep hole for about 10-15 seconds and quits.
I dried off the plugs and plugged the wires on each plug, layed the plugs on the maniflod loose, then cranked the engine. Each plug has a nice blue spark.
I've rechecked the rotor several times bringing number one up to TDC(compression) and each time, it's right on.
The last thing I did was pull the intake/exh manifold. The outside nuts weren't very tight but the center nuts were. After pulling it off, you could tell the center of the manifold was leaking. It just seems the engine should have popped, spit, backfired, at least did something, but nothing, just spin fairly fast with no signs of a fire.
Any suggestions would be greatly appreciated. I thought I could figure this thing out in short order, but the jokes on me
I have to order the manifold gaskets before I can continue.
