Today I got word of another loose carb bowl (MA4SPA). It appears that aircraft with long "snoot" air boxes are Loosening some carb bowl screws.
The bend over locking tabs just don't hold very well. When I was building, I was warned of this "common event?" The fix... Keep the distance between the FAB and the cowling air intake at least 1/2" and replace the screws with 10-24 X .750" allen cap screws, drilled for safety wire. and wire em up.
The screws are a tad hard to find. I found some at McGuckin Hardware in Boulder co. They are also online
Them "other planes" and our cool EXP. planes have both been affected
