Hey All thanks for the replies! Sorry, it’s been this long since I’ve been on. This is a managable issue but it’s mainly annoying and in the dirt/rain it’s a one-tire-fryer since I have to over-rev for the clutch, but don’t want to burn the clutch at the same time.

Ragragtimetime: I have used RockAuto for most of what I’ve gotten so far. Except I get a killer discount at Napa so will usually get common items there. But the shocks and filters I did get there. Also many parts for my other projects. To answer your questions this little beast blows no smoke at any RPM or speed in any weather. Runs like a complete champ. By “flat spot” it seems as if during the power band it either leans out or runs rich for just a little bit until I throttle through it. Due to no smoke I believe it’s a lack of fuel at that rpm (also no tach).

Ratesheet: I hadn't driven it for a while (motorcycle season) but
drove her today for the first time in a while. And I decided that with the upcoming oil change and checking of the rest of the fluids I’m going to check timing and inspect the distributor. I did change plugs & wires but know timing can be a PITA. So will grab the old timing light and see what happens.

Geezer101: I’ll be doing this tonight…..I truly believe it’s an issue with a vacuum line but have no knowledge, but I’m going to print off this thread and take it home and give it a shot tonight. I do have a rebuild kit for the carb and if the lines don’t fix it I guess I’ll take a thousand pictures while disassembling because I’m afraid I’ll cross a line while re-installing. But my other thought is if this vacuum line doesn’t do it then I’ll slowly dis-assemble while on the truck and inspect diaphragms and such. I hope it’s a line though!

But since this post I have additional done the following and none has helped the issue:


  1. Muffler was disassembled and the bearings checked out. Didn’t forget the horn bearings either!
  2. Blinker fluid was flushed out and replaced.
  3. Took an exhaust sample and sent it in.
  4. Fed the hamsters in my differential that keep the thing rolling. Can’t let them starve!
  5. Put my 17month old boy in coveralls and a gas mask with a K-bar and sent him under the truck to find the gremlin who I think is responsible for this issue. Boy came back, mission failed…..
  6. Filled my tires with helium hoping to lighten my overall weight allowing for better MPG and efficiency
  7. Installed a red “GO FAST” Button on my dash. Couldn’t figure out what to hook the wires to, but it looks cool
