So over to you guys, if you can offer any help or info I'd appreciate it. I've collected it from the workshop now and thinking of getting into it myself. The next step the workshop suggested was to fit a new carb, but to be honest at £100 +VAT, this is likely to make it uneconomical to repair, given the time and parts already put into it. Brand new snap in air purge pump primer bulb assembly for many brands of chainsaws and trimmers that have the snap in primer assemblies. Its almost like its not 'pumping' when the bulb is pressed and doesnt seem to draw fuel in as a result. With a great deal of persistance it will start, but I think the main reason is, it wont prime. The saw has also been fully pressure & vacuum and compression tested.

WALBRO : WA, WT, WY, WYJ, WYK, WYL, WYP and WZ carburetors that require a 3/4' OD x 9/16' HT primerbulb. I have a MS192t that was running fine, was left on the shelf for a month or so, then wouldnt run up properly.Īs my dealer had just sorted out a 200t of mine very well, I thought I'd pass it over to them rather than me having a go and struggling along.Īfter two full days of the carb being in the sonic cleaner, replacing all fuel lines, input line, primer bulb, full carb kit and many hours building and re stripping it, its no different. Not compatible with greater than 10 ethanol fuel. Hoping someone can help me out with this one!
