I'm cleaning my equipment getting ready for the 2k3 season. I clean the carbs and air filters on my BR400s . My help always complain how hard it is to start the stihl br400 blowers. It usually takes 3 pulls in choke mode. It starts to fire. Then 2-3 pulls off choke and it starts and runs. My question is for any tips or adjustments I can make to improve ease of starting? If the blowers are hot enough they will start right back up but even the 15-20 min between startups cools them down enought to require choke mode. I haveNOTreplaced the sparkplugs!
