of course this happens right when I need power. Seemed to run fine 2 days ago. I've got about 100 hours on her with this exact set up - nothing has changed.
I have been cranking all morning and can't get her to catch. I run WVO, but always run store-bought diesel the last 5 minutes before shut off, just to clean things out. Still, I pulled the injector and cleaned off any carbon build up. I check it by hooking it up but not bolted down, and can see the mist coming out properly. I can HEAR the injector doing the 'squeech' when it is bolted in.
When I pull off the valve holder in the 100th attempt to start it, it almost seems like the compression isn't as strong as it should be. Could I possibly need to change the distance of the rocker touch points?
I've made sure store bought diesel is running all the way through, from the filter to the pump to the injector. Valves are rocking. I have used that 'seafoam' stuff as an additive in the store-bought diesel, and I have used old gas as a thinner for my WVO. In fact, I guess that could be the only change in my set up - I used some DIFFERENT old gas - like 2 months old 87 octane to thin out the WVO.
Went out this morning, in the cold (45 F, not really cold) and wet and cranked for a while and couldn't get it to go, I did do one squirt of starting fluid in the air intake and it got going! Then, when I wasn't around... it STOPPED. again, all fuel lines have been checked, but even so, I have now bled the line enough to know it's not a fuel problem.
HELP. What I'm hoping for of course, is for someone to suggest some simple thing like "throw some HEET in" ... but I'll take any suggestions.
