Briggs Flathead / 12.5 Opposed questions
« on: September 08, 2008, 02:13:10 pm »
Hi all,
This weekend we had races in Princeton BC. It was a whole lot of fun. All of the races were super close with just about everybody competing evenly with others in the field. It was pretty sweet. This was the first time I have got to chase my dad and his 8hp with my new briggs 12.5 IC. His machine is set up really nice for corners, and the light machine combined with his 140-150lbs makes him an 8 that can give most 12 hp's a run for their money. I weigh in at about 200lbs, and my machine is a good 100lbs heavier when compared to his due to the fact I run a tranny (He is just a belt and jackshaft) and the heavy opposed. But the opposed proved to have the torque to give my dad a run for his money. We are pretty evenly matched now. We run pretty evenly now, and the only passing happens on mistakes, or when my dad lets me past because he figures I have a better chance of catching the guy in front.
Anyways, one of the things I have been fighting with is our club seems to have forgotten the fact we run classes . Because we only have 3 guys that run the above 12hp class, it always ends up that I run with them. I am just fast enough that I bump up to the B-main and miss the C-main. The problem is I am just fast enough to give the guys running 16hp a difficulty passing (not that I am blocking, but I definetly cant let them get the inside line), but once they are past, I just don't have the power to keep up.
One of the problems I am having is that the thing coughs and sputters when you hit bad bumps. Does anybody have any idea why it would do this? I put a vent in the side of the float bowl, but I haven't had any luck on getting the thing to not cough. If anybody has any ideas of what else it could be I would appreciate it. Any advantage I can get to help me compete against these larger mowers is a big benifit. Thanks
