Ron Hartil lived close to me when I worked in Duncan in 1989,he used to stop by the shop. I went in Sayward competition in 1989,didn't win but my brother video taped it and when watching it later he had taped one of Hartl's runs,THEN he played it in slow motion and viola-in the slo-mo I finally saw a trick Ron used to be so fast on the starts,I adopted and practiced that trick and it made my starts much faster! Bob Walker was a great guy ,his wife nice too. Most of the Pro competitors were well sponsored,I wasn't of course and Stihl never sponsored anyone but the B.C. Stihl rep supplied me with saws and parts under the table,my goal was to beat the kart engines in hotsaw with a Stihl saw(090),it was a fearsome saw,it was faster than the McCulloch kart motors,but of course my lack of experience was a detriment,but it was fun.

I built a 090 running a 34mm alky carb and pipe in the early '80s. But went on building myself a YZ125 bike saw because someone else built a 400cc Husqvarna bike saw.
 My YZ and my brothers Mac 101 kart saws built by Bob Walker beat the 400 almost every time in our local small wood.
In 1989 Bob Braden a Stihl dealer from Regina, Saskatchewan bought a 090 built by Stihl rep John Curry from London, Ontario head office. It was fast beat the Macs no problem and gave me a good run for my money.
It had a cut off head expoxied external tranfers and a wicked pipe and carb setup. Fastest 090 I ever seen.
Making a living with a saw since age 16.

Yes you really had 2 well modded 090's. On mine I designed and installed a billet cyl. head,5 transfer ports,7 windows in the piston,full race port timing,mx bike reed valve assembly,electronic ign. from another saw,and the huge HR carb,I was wanting to put a 34mm Mikuni on it but it ran well and I had no time with 3 other competition saws to build,044,100cc 064,and an 084 which was actually a pre-production test saw,no serial #,just #14 stamped on the crankcases,that one the Stihl rep gave me. I designed all my pipes.
I'm just glad I never injured myself running those things with so little experience. I sold all my saws to a nice American guy in 1992 who continued to run them for over 20 years on the pro circuit there, he won quite a few trophies and they never quit or blew up!
I can see you really were involved in racing.
