ok..here we go again. Had scott(scuffy) do a bottom end rebuild(replaced pistons and rod bearings) and ended up with a hard start problem. Would crank like hellfire, catch then immediately die..crank, catch, die then finally stay running. Well, this evening, at the Flying J in Ft. Pierce, Fl, went to start her up and nothing but crank. Through a process of elimination, changed the CPS(had a good one)..no change. Checked fuel..plenty of fuel so that wasn't it. Then, just for schyts and giggles, I took the plug out of the HPOP resovior(ok..so I can't spell it..sue me..LOL) and lo and behold it was BONE DRY! Filled it up using a make shift paper funnel and waa la! after just a few cranks, the ol beastie fired right up! Any idea what would cause the resv to drain out over a few hours?(When she's running, she stays running and will fire up if I shut her down for just a short time). Also..no apparent oil leaks in the gallery or on the ground. I'll be calling Scott tomorrow, actually later this morning as I look at the clock.. for his input but since its now 1:22 in the morning and I'm wired on coffee, figured I'd give Ya'll a shout.
