Fuel system and pressures HELP!!!! Please !!
I switched engine builders and was told to update. (private builder) Sold carb and bought new high volume fuel pump with a newer K&B carb. After like 10 nights and two engines I had to call it a season with no money to keep going.
Started out with a 2nd but the air cleaner started on fire a little so I had to adjust some things. Everything I tried just got worse. Had a rebuilt CV pump on and it made too much pressure at a dead head. I tried a new regulator and by passed fuel back to the cell and was told to run like 7/8 pounds. To make a long story short.......I tried a different CV pump. I tried different regulators. Went back to a cheap holly/ carter low volume pump. bought new fuel lines. pulled fuel filter apart. Pulled (top feed) fuel cell apart. Sent the carb to K&B to look at and rebuild. Ran fuel in and out of carb and regulator every way you can to have nothing but problems.
At first, engine would die trying to put heat in tired. Fell on face. Floats too high ? Then the car wouldn't start without 3/4 throttle wouldn't idle. Than after getting heat and get in line up it would quit. a mother to get started and wouldn't run unless it's at 3000 rpm. fuel pressure would drop as it got hot. dripping fuel out the top of carb. Tried turning fuel floats down. I mean the whole season/ all 10 nights was fighting fighting and more fighting fuel problems. The only thing I couldn't do was put old carbs on that I sold and I was broke. (Blake and Braswell)
So if anyone can help me with the newest and greatest with these cars rolling over on the right front and messing with the carb or not would be greatly appreciative. I some how cracked one block behind a cylinder and pushed water pass the cap and burnt a hole in a piston pushing (not a nice word)(not a nice word)(not a nice word)(not a nice word) loads of oil out the rear main on #2. Both engines are alum dart blocks and 18 degree heads. I'm running vp 114 racing fuel. Been at this for 16yrs and I've never been so frustrated!!!!
