I will try to keep this first post updated with all the race info for this GTG.
Build off rules are at the end of this post as well.

Chinese Build-off MS440 Races
will be in 20x20 poplar, no entry fees. The timed runs in the build off challenge will start when the chain touches the wood and end when the last cookie drops. At least two timers for each competitor.

440 class 1 - fuel and bar/chain provided.
440 class 2 - fuel and bar/chain provided.
440 BB/Hybrid Class - fuel and bar/chain provided.
440 class 3 - competitor can use their own fuel and bar/chain.
Class three stock chain shootout (no prize just bragging rights)
HLSupply will be supplying gift certificates for the winners in these 4 classes.

In Poplar 8x8 cants, no entry fee or prizes
Stock Saw Race - same gas saw for everyone, will run a new round chain on a stock saw with 20" bar picked at random from whatever shows up so nobody has an advantage, everyone is encouraged to compete in this class.

Farm Saw - bring your own saw up to 65cc and your own bar and chain, meant for inexperienced and new competitors, experienced guys are encouraged to help the newbies with technique etc...non ported saw up to 65cc with round chains, muffler mods, gasket delete, and hand filing OK, gas


0-140cc saw fun run any fuel, pipes OK, might even do cold start on this race for fun.
Vintage under 61cc stock appearing**, gas
Vintage 61cc and over stock appearing**, gas

In 8x8 poplar, $3 entry fee, prize is entry fees plus $25 each class (provided by CCC Racing)
0-3 cubic inches (rounded up to 51CC) stock appearing*, any fuel
0-4 cubic inches stock appearing*, any fuel
0-5 cubic inches stock appearing*, any fuel
0-100cc stock appearing*, any fuel
Unlimited stock appearing*, any fuel

THE MIGHTY DOLLAR RACE
In some nice long round 12-14” log any species that isn’t too ugly - $1 per cut and any saw used is open to all competitors, winner takes all.

*stock appearing means all covers are in place and it started life as a chainsaw and still looks like a chainsaw
**vintage stock is first produced before 1975 (according to acres internet).

I will bring along two cant stands this year so we can keep the races moving on Saturday, and have a practice log for new guys to practice on as well.

Hopefully this provides a chance for everyone to get in on the action :)

Class 1
This class is for guys that don't want to do any machine work. Any aftermarket 50mm 044/440 top end is allowable. You are allowed to use any aftermarket rings......OEM rings are not allowed. You can use any circlips, or wrist pin bearings you deem necessary.....AM or OEM. You must use the piston, and the wrist pin that matches the cylinder that you choose. If you use a FarmerTec jug......then you have to use the FarmerTec piston as well. You can use any gaskets or seals that you choose......AM or OEM. OEM fuel lines and filters are legal. All other rubber bits (intake, impulse, etc) must be AM. You must use the AM carb that comes with the kit. The carb must be the one that came with the kit unless your carb is complete crap. If that is the case, then only another AM carb that is a replacement 1128 series carb can be used. The kit muffler and cover must be used. You can mod the muffler any way you see fit, except to create a tuned expansion chamber type of unit. The bearings and crank that come with the kit must be used. The oil pump can be modified to increase flow, and the worm gear can be AM or OEM. The coil and flywheel must be AM. Recoil parts can be changed to OEM with the exception of the cover. Starter rope, and handle can be OEM or AM. No machine work of any kind is legal in this class. No sanding, milling, filing, lathe work, non, nada. Base gaskets can be AM or OEM or homemade or non-existent. No external transfer ports can be used. No finger ports or bridge porting allowed. Working choke is required. Airfilter must be from the kit, or the white AM HD2 style replacement. No MaxFlow setups allowed. Air filter cover must be installed. No modifications can be made to the covers. Chain and fuel will be supplied at the event. I reserve the right to add to these rules if I forgot something, but the meat and potatoes will not change.
Edit: Carb mods in Class 1 will be limited to spring and jet changes. Jet meaning if you gotta drill a welch plug or whatever to get it working good then that's ok. Just no boring the carb throat or venturi.
Edit: Just to clarify. Port work is allowed in this class. No finger or bridge ports. No external transfers.
Machine work to increase compression is not allowed in any form.
No BB kits.

Class 2 :

Same rules as Class 1 with these exceptions.
Machine work is allowed to the squish band, cylinder base, and piston.
Finger ports, and/or bridge ports are allowed.
No two piece heads.
No external transfers.
OEM carbs are allowed as long as they are intended for the 1128 series. Carbs can be modded for flow, but a working choke is still required.
OEM intakes and impulse lines are allowed....but must be intended for the 1128 series. No intake blocks. No 084 intakes, etc.
Fuel filters can be gutted for more flow.
MaxFlow, or OEM air filters can be used, and covers are optional.
OEM coils and flywheels can be used.
Edit: Just to clarify. No BB kits in this class.

BB/Hybrid Class
Same rules as class 2 with the exception of displacement. Any aftermarket 1128 top end can be used.

Class 3
Same rules as the first two classes with these exceptions.
You can use any aftermarket top end. Period. Fit one from a 090 if you can.
Two piece heads are legal.
External transfer ports are legal.
Use any carb you like. WB....HL.....whatever.
Use any coil/flywheel combination you like.
Methanol, Nitro, Oxidized fuels are legal.
Make your own chain.
Tuned pipes are legal
Air filters are optional.
Fuel filters are optional.
In other words....in this class anything goes as long as you use the kit parts for the bottom end, and an aftermarket top end of some kind.
EDIT TO ADD CLARITY: Any aftermarket pistons and jugs are legal. The piston does NOT have to match the jug.

Used to be some shows that ran the 6ci SA class. Thinking in KY TN AL LA.
Not sure on all of them anymore.

We always had 6ci class at my gtg's.

Guys asked me about fuel in some PMs and texts - for the build-off saws below class three the fuel is provided regular gas mix and for the Stock saw, farm saw and vintage classes we will go with regular gas and open season on the other classes. INFO AADDED TO FIRST POST.

On a saw less than 45cc?
Yes, on fuel and gas. LP chain too makes it dicey :)
R&D. A juiced up 260 with LP and 10 seems scary too. Not sure I want to try that, yet. A lot of work in just cutting and thinning bars down. The small saws should be done at 10. The case or crank is going to pop if you stuff it.
