still working out the "bugs"

Got the oil leak fixed from the front of the motor. It took getting a new timing cover, straightening the front motor plate, new seals (again) and a speed sleeve. A bit of over kill perhaps, however, NO MORE LEAKING FROM WHERE IT IS NOT SUPPOSED TO!!!! :smile:

Now to the fuel issue. Has anyone had any problems with the new fuel tank from ebay?

I know that I have a richness issue. Still trying to set the carbs. Replaced fuel pump (elec.) fresh line from the tank to the pump. I just don't know???

It is as if the car is starving for fuel. It happens intermittently. No real rhyme or reason. I can set the regulator up to 3 lbs and it fixes the problem for a bit. I have still had the problem at 3 lbs. Thoughts???? If I run 3 1/2 lbs I get fuel in the oil.
 
Re: still working out the "bugs"

Certain new fuel lines seem to dissolve with gasoline.
I had chain auto store 1/4" fuel line that was melting from the inside and clogging up my fuel pump and carbs.
This happened in the first 100 miles, it took me 300 miles of aggravation to finally figure it out. VW 5mm cloth covered fuel hose made in Germany, it's not cheap, but the cheap stuff wasn't worth the aggravation.

I had high end braided line on her during the problem. :frown:
 
Re: still working out the "bugs"

What volume are you getting at the carb? How many gallons per hour?
 
Re: still working out the "bugs"

Don't know. Was thinking about putting an inline gauge on before the carbs just to know what was going on.
 
Re: still working out the "bugs"

Was also wondering. I have 5/16 hose running from the tank to the pump. 5/16 hose running from the pump to a 5/16 steel line. 5/16 hose running from the steel line to the regulator. And then I step down to 1/4 line from the regulator to the carbs. Could this be causing problems?
 
Re: still working out the "bugs"

I'd be among the least to know. FWIW, I had a Weber 38/38 on my last toy and suspected fuel volume issues (was wrong in the end.....) but I moved the fuel pump back to the tank area (where they belong) and ditched the OEM fuel line (1/4") in favor of 3/8" all the way up, ditched the pressure regulator (pump was doing 4ish which is fine for a Weber) and then I had 23 gph (started with 16). Easy to check (if you have an electric pump) pull the line off the carb and let it pump into a container, time how long and how much and do some math. I may have to do this same routine to the Midget as she's being fuel starved occasionally (for some reason) I'm getting about 7 gph right now with the same pump that was on the last toy, but in the engine bay and pulling through the stock line. 7 gph is probably not enough under high load conditions and there's no harm in suppling as much as you can so long as the pressure stays low, as I understand it.
In the end, I probably would have been fine with my original set up (16 gph) since in that case it was a loose venturi tube in the weber that had rotated 180 degrees and was then shooting fuel up instead of down on one barrel. Weber 38s are more sensitive to fuel supply they say since the demand can be more but the fuel bowl has a relatively small volume.
 
Re: still working out the "bugs"

hello, just a shot in the dark, but could you just put a 5/16 line in place of the 1/4 just to see if it makes a difference.
 
Re: still working out the "bugs"

The inlet to the su is 1/4. I can do the fuel test, just for fun, if need be. How many gph should I be getting for twin SUs?
