Walbro WT526 Trouble
Working on an MTD 31cc tiller - which is a good engine from my experience.
Replaced fuel lines, purge bulb, pickup.
Rebuilt carb with K10-WAT kit. New diaphragms, gaskets, needle assy. Screen clean. Replaced big welch plug but not small one.
The trouble: Cold starts are awful. 50 pulls with choke- gets flooded. 50 pulls no choke - no fuel. 50 pulls half choke - no fuel. Priming cyl with mix gets it to start after 5 pulls. Once hot - starts REAL easy with a half pull. And runs great on throttle up and WOT. Resarts great every time until it cools for 15 mins.
I tried a makeshift high idle setting and no difference.
What should I try next?
