Hi Norm,
Speaking of those handlebars, I just used that machine for the first time today after 3 years or so of it sitting under blankets in the shed.
Wanna hear a funny story about it ? after 15 minutes of using it the brand new Briggs motor on it started to knock rather loudly. I thought WOW ! WTF is going on here ???
Pulled the engine off the machine and opened the crankcase only to find both cap to conrod bolts had come adrift and the rod was flopping around on the crank. Unbelievable !!! only that would happen to me over the Xmas break wouldn't it.
Anyway rubbed out a few marks on the cap and reassembeled it and did up the bolts tightly using some Loctite and put it all back together. It ran flawlessly for 3 hours after that.
Cheers,
BB.
