I did as you advised Norm K and fuel came out the tickler alright -non stop. So I removed the brass stub once again and repositioned the needle -I pushed it in too far. This time the fuel came out only with the tickler down and after a few pops it came to life. Now only a few small things to sort like the kill switch, the loud exhaust, replacement blades, front axle shims to arrest the awful loose play and replace the front left wheel and it will be ready for work on the front patio.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
