Chased a gremlin down on this Compkart I recently picked up. Couldn’t get it to run worth a hill of beans. Threw my backup motor on it and experienced the same problem…running pig rich and dying. The VP on the bench that came on the kart has less than 3 hours on it. I had a brand new backup carb sitting next to the grinder just in case.
After swapping carbs I fired it up and hadn’t put the drain/vent line back into the catch bottle and it was running perfect….until I put it in and it immediately started running really rich again. That’s when I realized the single hole the previous owner drilled in the cap was creating back pressure in the bowl and flooding the motor. Drilled a bunch more and viola…problem solved. May go to dual catch bottles like my Praga even though this is now working.
Pulled it out of storage and wow, it needs a little TLC
Injured my back/ribs a week or so ago so I’m a little lazier than usual with tidying and placement of things.
These bad boys? Just frame protectors you put on the bottom of the frame to keep it from contacting the ground. Keeps your frame from getting chewed up. These particular ones were made from aramid fiber (aka Kevlar).
As some of you might know im a driver and a parttime mechanic for myself… that includes me cleaning my kart after every testing and doing everything i can when im not on track. So i took apart my whole chassis after a big crash last weekend and turned out i had a bent steering columt, tie rods, and pedals. I sorted that changed to a soft axel from a MR to S and i got a new setup: 5mm camber (2.5mm/side) 2°caster
And a ackerman on the lowest position! Testing in senior today
