new restrictor (return line)
on the original attempt at a return line, this was before getting it at the bowl, I found this check valve in a vacuum line. Gas proof of course. works on low psi. less than a pound. Car ran with it. the error proved to be return line needing to be after the float bowl gains priority, not before.
I thought it may be too big of an opening. not acting as a regulator enough. I added some piping I found in the chevette carb. pressed in, then quickly lit with a bic. this should restrict it to just right..been messing with different sizes. A .035 mig welders tip is in the return line now, and the bowl gasket told me it is still getting quite a pile of fuel in a hurry...freakish.
this will do it. Still no regulator needed.
seems as though, I am tuning this into a two barrel with no needles on the jets. more than a coincidence. that is what kind of carb was in it.
this will also add one way into return..can't surge back at the carb.
This photo captured all the intersections of the fuel lines going by each other.
check valve restricted, installed into return line. I found it acts like it is starving more than before. although a whiff of fuel goes with it when the hesitation happens. An emulsifed odor, not a straight shot leaky one. This is good news. my carb tuning nose tells me. I am assuming it is choking on aerated lines. I blew into return line and found that the .035 did not fill it, it gave it an air bubbled spray. Not check valved, it sucked this back into engine when it needed to. I am forcing the hard line fuel now. Something is much tighter with the gasket for float bowl..just going to force a runtime. I wonder if this tortured monojet ever ran proper, tight into its channels. the float bowl gaskets are freaking terrible. it is all there correct now, plenty of fuel. engine sounds terrible. needs an oil change. the front side of carb has control valve for vent can hooked up at carb, and the top vent that would normally return under full vacuum into the air duct (slow that crazy function down).
I will feel bad if I blow it..but a sacrifice had to happen. the gewkster hooked it up carzy. I am just getting it right the american way 25 years later. it is useless describing how tough that really is. if a chunk of valve breaks off and pulverizes the whole thing, I will laugh.
I got it to pop, biggest ever..this means moving more than ever. the vent can having a real function must be full of a change temporarily right now. the hesitation seeming a bit more elongated..but the engine climbs it. Something familiar about this..it will come to me. I know to just drive and run it. get some good oil in quickly. clean the reusable filter out...
edit: this did work. quick snap of reality in these retarded city streets.
Since this posting, I have found the brake booster is very strong.strongest I have ever felt. The guess about air holes for idle were correct,old bowl gasket could not do its job...for years and years. the hitachi was the same..but intermittent. the lucky seat to air loose must have been the lack of venting getting its way. So that is how the original setup did not become a complete bomb..only became a little one. An error got its way to correct when it needed to. I guess I deciphered the past with a current problem, building it on your own can do that. generalize 100 other cars with just one.
I got a whiff of the old gasket. that is some kinda power getting kicked out. off-idle to partial is existing. I give it a thumbs up..I am real curious about the other end. top end runout. Seems it is all there, thinking the needle over as much as I have. I am in a place that has 3 nanoseconds for error. People climb out of the woods to go through these streets of the only city. the accidents are funny when no one is hurt.
hesitating throttle is not an option. diesel thump of an old boxer to a scream not much heard of in the northwest USA woods wth lift kits and dangling EGR fungus.
how in the hell did they not see F1 in a self balanced short stroke, liquid cooled all aluminum boxer?
no rocket scientist needed.
just going to let it sit around, give it another long run again in coming weeks..funky thumpy sound the little engine makes... I love it.
