Here's my F up. People across the street come over asking if I can look at their yard vacuum that won't start, he's already had his next door budy help him and it still won't start. He knows I work on stuff and he just had shoulder surgery and needs a favor. Leave it with me I'll take a look at it. O confirm safety switch and spark are good, priming with external fuel source makes it run till the prime runs out.. so it's a fuel delivery issue. I pull the carb, bowl is full and clean, I check float level and needle and main jet and air bled circuits,, with wd-40, Iam out of carb spray.. all apears ok.. the floatbowl bolt has small passages that seem clear. I put back together and still won't run..well at this point a carb issue is indicated.. the unit is fairly new and service info says 12 month warranty.. so I msg them about my findings and to check date of purchase, looks like we got a plugged carb circuit... well Thinking further, I can verify my diag if I put my carb from my vacuum on their unit, if it runs normal again. I'll know fir sure the issues in the carb. So I do it and sure enough it runs like a champ now... so I pull their carb apart again and recheck with carb spray and jet drills, I find the float bowls bolt passages are the lowest point within the carb and smaller than all other passages, so any dirt had to pass thru it first, plug could be here.. so I start sticking jet drills in it before I try to re-verify flow. This screws me because after the jet drills it's bonified clear.., but its condition prior is not exactly known, Iam inferring it was actually plugged... so I blow thru the carb circuits one last time and out pops the needle seat and it flys like a foot ball being kicked into the end zone. It land on a jeep in my stall and makes no noise.. 1.5 hours later and complet sweep of shop and jeep, all I can come up with is it went into the cowl vent of the jeep and could be in the hvac unit... who knows dam thing is tiny..
So I buttoned up their unit with my carb and gave it back fixed... they were grateful not having to deal with sears and the BK filing... and made a peach cobbler pie..
I ordered a new carb and a needle and seat so I can get mine running, I just had to know where the issue was, kicked myself for a few days lol.. cost me about $65
