Well, this is my second post here. I am not unfamiliar with OPE, as I have been an active member over on SBF for sometime. But this machine is giving me fits..... It is a friends machine, that has handed off to me to resurrect.
The details:
What I found when it arrived:
After getting things back together:
Other observations:
Am I headed in the right direction? I'm more knowledgable with the old "L" heads, these OHV's seem to be more finicky.
The details:
- Briggs series 12000 (12S912-0121-B1)
- Attached to a Troybilt pressure washer, but I have seen, and worked on lawn mowers with this series of engine.
- What has been done, Oil change-due to fuel in oil, Carb- ultrasonic cleaning, due to fuel in oil, added filter and fuel shut off, valves adjusted
What I found when it arrived:
- the machine would only backfire, thankfully after find gas in the oil.
- no fuel shut off- resolved
- sheared flywheel key- resolved
After getting things back together:
- would not fire with out dripping in some gas into the intake
- Backfired, and sheared the flywheel key, again.
Other observations:
- it appears to have reasonable compression (pull test approximation)
- valves were not not far out of adjustment.
- as far as timing, the only other thing that I have not checked, is that the camshaft is synced with the crank, I have not done so to preserve the gasket. But I guess this may be my next step.
Am I headed in the right direction? I'm more knowledgable with the old "L" heads, these OHV's seem to be more finicky.
