Have now stripped the top off the pump as the only thing to my mind is the governor assembly must be somehow stuck on both pumps. Well, on opening one up it's full of nasty dark waxy deposits in all the nooks, crannies and pivot points so guess that's the problem then! I think this is due to having sat with veg oil in the pump over time although what came out of the original looked/felt like red diesel to me so not sure why that one gummed up, if it has.
Anyone else experienced similar issues with a VE pump that's sat without it's fuel supply hooked up for years? Glad I was ready with a CO2 extinguisher since depending where the governor had jammed it has potential for runaway, perhaps something to be extra cautious of when resurrecting long-sat diesel projects, have a means of starving the engine for air handy before you even try and crank it up.
Main thing I'd like to question here, is could the gummy internals account for the smoke also, in the form of way out-of-whack injector timing? I've left the pump body full of 2 stroke petrol mix tonight, to help free it up & the "lid" is in the dining room getting cleaned out. Attached is a short video of how it behaves (ignore the dancing engine, it's not properly mounted yet)
Can't be much else other than governor right? and the smoke looks/smells like timing out
Oh, and thank you to Evilally, you can just see the inlet manifold in the video haha, that and injectors for Black arrived this morning cheers
