j150txesb (1990) sneezing

[elhombre]

first run this season. Overhauled carbs- disassembled, cleaned, installed kits. I just ran it on the hose and it started "sneezing" at idle. Seemed like it was coming from the bottom carb. Appreciate any input - Mike

Re: j150txesb (1990) sneezing

did you remove and all the jets, and spray out the ports?


handling hose increases chances of this, re contamination carbs.
Ethanol and fuel lines
replace all fuel line with Alcohol resistant lines. Ethanol deteriorates, the rubber lines, then they start to sluff off on the inside, going directly to the carbs. Settling to the bottom of the bowl. Contaminating the carbs high speed jets. clean a rebuild carbs, flushing fuel line before connecting to carbs.

Thanks Tashasdaddy, I found the pulse limiter disconnected. sneeze is gone, I'll put alcohol resistant hoses on the list of things to do. (Yes,I removed all the jets and cleaned them). Thanks again - Mike
